Pot Grows Destroy Fish Habitat

Brad Job: Rapacious Grows Destroy Habitat, Undo Restoration Work – January 29, 2012

I’ve been fascinated by water and the organisms that live in it since I was a child. When three years of sea duty made me fall in love with the ocean, I decided to pursue a degree from HSU in Environmental Resources Engineering, which I completed in 1993.

Since then, my career has focused on water quality and water resources. For the past 10 years I have had the honor and privilege of being part of a team of professionals that steward some of our nations’ most spectacular public land. In this occupation I have also been witness to many environmental sins that have occurred as a result of marijuana cultivation.

As a pragmatic environmentalist, it is not my job to deride marijuana or its use. But, similar to the environmental effects of logging, the problem is not necessarily that one grows pot, it’s about how one grows pot.

Regardless of how one feels about marijuana and its legal status, anybody that understands just a little about aquatic ecosystems has to admit that widespread cultivation has bad consequences for fish. It degrades the quality of our rivers and streams, which to me, are the core of what makes northwest California special.

In reference to one of last week’s cover stories about illegal excavation and un-engineered fill(‘Shocking’ environmental damage from outdoor grows, Eye, Jan. 18) I can attest that the additional input of sediment eroded from grow-related excavations permanently damages habitat for imperiled salmon and trout populations and undoes the benefits of millions of dollars’ worth of watershed restoration work.

However, increased sedimentation is not the only or necessarily the worst environmental consequence of rapacious pot growing out in the hills.

The giant hunk of failing fill is located right above Bear Creek where it exits the King Range NCA could not be in a worse spot as far as fish habitat goes (notice the clear creek in the upper right corner).

Recent research has shown that 80 to 90 percent of the nitrogen in coastal watersheds historically came from the ocean, much of it in the form of return runs of salmon and steelhead. However, dwindling fish populations and environmentally oblivious pot growers have turned that dynamic on its head.

Now, growers dump hundreds of tons of excess fertilizer into these watersheds annually. The most obvious consequence of fertilizer overuse is increased algal growth, which is most likely why toxic concentrations of blue-green algae have been observed in the Eel River in recent summers. Excessive algal growth kills fish and the organisms that they feed upon.

In addition, outdoor grows frequently discharge rodenticides, insecticides and fungicides into the environment; divert springs and creeks for long distances; and leave vast quantities of trash and black poly-pipe behind.

And then there are the diesel dope grows. These operations often improperly and illegally store large quantities of diesel in plastic tanks that are prone to failure. And those that do use metal tanks almost never have secondary containment and often have leaks and spills.

It is worth noting that fuel distributors that dispense fuel into such tanks are also committing a felony. If anyone wants to observe the environmental consequences of petroleum spills in aquatic ecosystems, they need only to travel to an urban stream to witness the reduced abundance and diversity of invertebrate species, which are the base of most aquatic food webs.

Then consider the water diversions, air and noise pollution from inefficient generators, and the random dumping of fertilizer-laden potting soil. And I can hardly bear to ponder the sad irony of burning fossil fuel to make light to grow plants in a manner that is literally 99 percent inefficient, all while it is warm and sunny outside.

As long as the marijuana status quo and large profit margins remain, it appears inevitable that some of the worst crimes at marijuana gardens will be environmental ones.

The citizen’s suit provision in the Clean Water Act might be a big enough hammer to change some landowners’ behavior if a motivated team of attorneys and environmental scientists were to respond to a specific incident.

However, the sad fact remains that the underground economy is creating really bad consequences for the increasingly fragile ecology of our rivers and streams. But, if this letter makes only one grower reduce their fertilizer and agricultural chemical use or cause less erosion, the time it took to write it will have been well spent.

Sincerely,

Brad Job, P.E.

Conservation effort sets priorities for habitat

By DOUG WARNOCK

For the Capital Press

Forest resources, arid lands habitat and Puget Sound health were the areas selected as priorities for the Washington State Coordinated Resource Management program.

Washington’s CRM Executive Committee and CRM Task Group met together to establish program priorities. Reduced funding and loss of a full-time program coordinator precipitated the need to streamline activities and focus on high-priority needs.

The three areas deemed of greatest need were:

* Forest resources, emphasizing water issues.

* Arid lands habitat, focusing on sage grouse and endangered fish.

* Puget Sound health, emphasizing improved water quality.

The CRM Task Group is implementing a plan to assist new groups organized to address issues in the three priority areas, while continuing to support existing CRM groups across the state. The Task Group is led by Kevin Guinn, Natural Resources Conservation Service range management specialist, and facilitated by Ray Ledgerwood, Washington Conservation Commission Program Facilitator.

Coordinated resource management is a collaborative approach to resolving issues and improving management of land and water resources. The approach has been in existence in Washington state for over 50 years and has resulted in improved health of soil and water resources across the state.

A group in the Tenmile Watershed of Whatcom County stabilized stream banks and improved fish habitat. It involved local dairies, poultry producers, fruit and vegetable farmers and many community members.

A program in Klickitat County resulted in the development of 30 springs as water sources for wildlife and livestock, installation of 50 miles of fence to protect riparian areas and trees planted on 100,000 acres for forest renewal.

These are just two examples of successful programs. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

Planning for any program is done by the local people who are responsible for managing the land and who have the best knowledge of the situation. Resources of the State CRM Executive Committee and the state CRM Task Group are available to support local groups as needed.

The program planning process empowers local people to solve land use and natural resource issues through collaboration. It brings people together, enhancing communications and reducing conflicts, to help find common ground while working toward the achievement of mutual goals.

Consensus is the basis for success in planning. The approach works because planning together across ownership lines and management boundaries results in better resource health, helps people meet their objectives and minimizes conflict among participants. While there may be a difference in how individuals view a problem or situation, all have an interest in the land’s well-being and can find mutual objectives for its benefit.

The CRM Executive Committee is composed of the heads of the state and federal agencies associated with land and water resources. The CRM Task Group includes representatives of the same state and federal agencies involved in the Executive Committee, as well as several members at large. All are dedicated to enhancing the health and well-being of natural resources in the state.

Doug Warnock, retired from Washington State University Extension, now lives on a ranch in the Touchet River Valley where he consults and writes on ranch management.

New reefs for fish habitat in Maryland

Artificial reefs for fish habitat
fish attractors

The new fishing season might seem like a long way off but we’re really only a couple months away from when folks will begin extracting fishing rods from attics and sheds, pulling winter tarps from their boats, and reviewing their charts, just to make extra sure they’re set and ready for the fun times ahead. The natural optimism found in most anglers may foster aspirations for a new fishing season filled with beautiful weather and stringers full of big fish. But in these times when it seems fishermen are so often hampered by political, environmental, and economic issues, even the most optimistic angler can sometimes have trouble keeping a smile on their face when the winter news carries so many headlines of “doom and gloom.” So it’s always refreshing to hear some good news about positive developments within the fishing industry. On that note, let me reintroduce to you the Ocean City Reef Foundation and MARI. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

Its activities may not always capture front-page headlines, but since 1997 the Ocean City Reef Foundation has been busy creating and enhancing offshore fish habitat through an ever-expanding network of artificial reefs. From boats to barges, cable to concrete, tanks to trains, in recent years Reef Foundation administrators have strategically submerged so much material off our shores that give fish traveling through Maryland waters a reason to reside and reproduce off our coast.

There have always been artificial reefs off Ocean City. But, until the Reef Foundation got to work, offshore structure was restricted to a small handful of boats and ships that accidentally sank, or structure that was intentionally put down by a few well meaning anglers on a very limited basis. Consequently, local wreck fishing used to be practiced by a relatively small segment of local anglers who, through years of trial and error, acquired the coordinates to the bulk of offshore structure. Since no one wants to schedule their day around fishing a certain wreck and then find someone else already anchored over it, once obtained these coordinates were very seldom shared with other fishermen. With such limited opportunities, local wreck fishing was destined to remain one of Ocean City’s best-kept secrets.

Not any more. The OC Reef Foundation has been so successful at seeding the waters that fishermen no longer have a need to keep a good thing to themselves. There’s plenty of places to fish, and plenty of fish once you get there.

When structure goes down it immediately begins to provide safe habitat for aquatic life. In relatively short order, entire living communities can establish themselves on, in, and around the structure. In areas where the ocean floor was little more than smooth bottom there becomes a living reef and complete food chain, from tiny microscopic plants and animals to large predators. The Reef Foundation is just getting warmed up; they sink structure all year and have lots more on the agenda.

A few years ago Maryland also got into the reef building business when they kicked off the Maryland Artificial Reef Initiative (MARI), which includes over 60 private, state, and federal partners, and acts as a funding mechanism (using private and corporate donations) for reef development in Maryland. It’s a volunteer organization dedicated to preserving, restoring and creating fish habitat in tidewater Maryland. Funding for MARI comes from the Coastal Conservation Association, Maryland Department of Natural Resources and the coalition of donors and partners. MARI brings together a coalition of diverse stakeholders to accomplish meaningful and measurable goals that not only benefit the sport fishing industry, but also provide priceless marine habitat. Last summer, MARI had a hand in the offshore sinking of the 564-foot warship Radford which is now in striking distance of Maryland, Delaware, and New Jersey fishermen.

Though spring is still few months away, sooner or later it will be here and happy anglers will once again put to sea in hopes of enjoying their best fishing season ever. Fishermen should take comfort in knowing that the Ocean City Reef Foundation and MARI are working hard to ensure that such hopes can indeed become reality.

Recreational Fisheries Award to Kamloops

Minister Shea Presents 2011 National Recreational Fisheries Award to Kamloops Volunteer

KAMLOOPS, BRITISH COLUMBIA–(Marketwire – Jan. 19, 2012) – The Honourable Gail Shea, Minister of National Revenue and Cathy McLeod, Member of Parliament for Kamloops-Thompson-Cariboo, on behalf of the Honourable Keith Ashfield, Minister of Fisheries and Oceans and Minister responsible for the Atlantic Gateway today presented Mr. Mo Bradley with a Recreational Fisheries Award in their home community of Kamloops.

“Mr. Bradley has contributed to Canada’s world-renowned recreational fisheries,” said Minister Shea. “It is important to recognize the hard work of volunteers who are committed to building sustainable fisheries in their communities.”

For over 30 years, Mr. Bradley has been developing and promoting recreational fishing in the Kamploops/Shuswap area of British Columbia. He is passionate about fishing and about teaching others how to fish, particularly young people. In teaching others, he never emphasizes the catching of the fish, rather the whole experience of fishing including observation of the natural world.

He has been an active member of local fishing clubs, contributing to expansion of programs to provide more fishing opportunities and educational experiences. As a board member for the Habitat Conservation Trust Fund, Mr. Bradley lent his expertise and understanding of the needs of the fishery to ensure that fisheries projects would be of long term benefit to the resource.

A master fly-tyer, Mr. Bradley donates more than 3,000 flies each year to conservation groups to raise funds; flies tied by Mr. Bradley are much in demand. Passing on his knowledge and expertise to the future generation of anglers is considered by his peers to be the best aspect of his accomplishments overall.

“As Mr. Bradley is committed to ensuring that recreational fisheries are preserved, so is our Government,” said MP McLeod “We are proud to honour the efforts of such dedicated volunteers who make such an important contribution to this important tradition.”

Canada’s National Recreational Fisheries Awards were created in 1989 to recognize outstanding contributions by individuals and organizations in areas such as recreational community leadership, restoring and enhancing fisheries and fish habitat or promoting conservation and sustainable recreational fishing.

Fraser River fish habitat threatened by gravel extraction

  Fraser River fish habitat threatened by gravel extraction

Approximately 280,000 cubic metres of gravel accumulated in the active channel of the river, this was largely offset by significant losses (4 million cubic meters) of over-bank sand on islands and river edges, resulting in little net gain of sediment. (Credit: janheuninck via Flickr)

B.C.’s Fraser River has become the battleground for the gravel industry and conservation groups fighting to protect one of the world’s most productive fish habitats. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

The Fraser has been a source of gravel for B.C. construction for decades. However, Fisheries and Oceans Canada (DFO) placed a moratorium on gravel extraction in the mid 1990s due to concerns about fish and fish habitat. Not long after the freeze, the B.C. Provincial government began to argue that gravel removal from the Fraser was necessary for flood protection as “massive” gravel accumulations were, allegedly, causing the river bed to rise. A series of public meetings was held to debate the issue and experts were called in to assess the scope of the problem.

Dr. Michael Church, a professor of Geography at the University of British Columbia, provided the most compelling testimony on how gravel and sand enter and move through the gravel reach. He estimated that while approximately 280,000 cubic metres of gravel accumulated in the active channel of the river, this was largely offset by significant losses (4 million cubic meters) of over-bank sand on islands and river edges, resulting in little net gain of sediment.

The B.C. government and proponents of the gravel industry incorrectly interpreted this to mean that 280,000 cubic meters of gravel and sand entered the gravel reach each year and merely “piled up” in the river causing a rise in riverbed elevation that would, over time result in increased flood risk. These groups argued that lives and property were at risk and pushed for DFO to lift the moratorium on gravel extraction.

In 2004, a five-year federal-provincial agreement was reached to allow removal of up to 500,000 cubic metres of gravel in each of the first two years and up to 420,000 cubic metres in the following three years. The agreement was touted as a long-term plan for reducing the flood hazard risk in the lower Fraser River.

Critics argued that gravel removal was only taking place in areas where it was easily accessible to industry and that removal from the targeted areas provided no flood protection benefits whatsoever. In addition, fish and fish habitat were paying the price. In one case, at a location known as Big Bar, removal operations undertaken in 2006 resulted in the de-watering of thousands of salmon redds (nests) and the demise of possibly millions of young salmon which were just about to emerge from the gravel. There was evidence to suggest that similar losses of fish had occurred at other sites as well.

The Fraser River is also home to the white sturgeon, listed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as endangered, with gravel removal identified as one of the key threats affecting this species.

Tweed river fish habitat in good hands

Jim Ryan, a state river scientist, surveys a restoration project on the Tweed River in Pittsfield on Friday, Dec. 2, 2011. Floods triggered by Tropical Storm Irene sent the river shooting into a new path that threatened a mill downstream. Road crews seeking gravel further altered the river, making it more unstable. To restore the Tweed, river scientists redesigned a 1,800-foot stretch of the stream, to make it more stable, protect private property and restore fish habitat. Ryan stands on gravel used to fill in the Irene flood channel. That area will be the river's new floodplain -- a relief valve during heavy rains and spring snowmelt. The river flows in its new, more stable channel farther from houses and Vermont 100.

PITTSFIELD — Jim Ryan stood with Ray Colton on the banks of the Tweed River on Oct. 7 and shook his head, more in resignation than disbelief. He’d seen too many places like this in the last month.

“What a mess,” he said. He made a note in his notebook: “Colton’s mill site: Site is hammered.”

The river running past Colton’s firewood mill looked more like an abandoned gravel pit than a babbling brook.

On Aug. 28, Tropical Storm Irene had ravaged this stretch of the Tweed, a scenic stream that borders Vermont 100 between Killington and Stockbridge. Highway crews compounded the damage. Desperate for gravel to repair the washed-out highway and its broken bridges, they drove excavators and dump trucks into the river and scooped out tons of stone.

The tracks of heavy equipment could still be seen as ridged indentations on gravel bars. Much of the river’s water ran in a stony ditch gouged out by the road crews, but the rest trickled in multiple threads through the gravel islands.

Just upstream, the river had jumped its bank, eating up the field behind Sarah and Gordon Gray’s house and carving a new channel that barely missed Colton’s mill. More than 100 feet of riverbank snowmobile trail had disappeared.

Colton was worried about what would happen in the next high water.

“I’m afraid the river wants to come right through the yard,” he said, referring to his millyard with its stacks of logs. He’d spent the night of Irene sleeping in a camper at the mill to keep an eye on the river.

Ryan shared Colton’s concern about damage from a future flood, but had other worries as well.

“From a water quality and fish habitat perspective, the conditions were just horrible,” he said later. “Think about fish trying to stay cool in the middle of summer. Instead of deep shaded pools, they would have this shallow, braided stream.

“Yes, the river might have healed itself, but it could have taken decades. Something needed to be done,” he said.

Irene had jerked Ryan, a stocky, soft-spoken man, from his job as a state watershed coordinator to join the state’s lightly staffed River Management Program. He had spent the weeks since criss-crossing the White River watershed to survey river damage and to provide guidance to towns about rebuilding bridges and culverts in more flood-resistant ways.

Before the arrival of Ryan and his peers, road crews had torn up river channels across central and southern Vermont. Vermonters were treated to the surreal site of excavators, backhoes and dump trucks chugging through trout streams to remove whole shoals of gravel.

Much of this post-Irene emergency work did not just destroy fish habitat. It left rivers unstable — prone to severe erosion of their banks and sudden changes in course during high water — and thus potentially dangerous.

The challenge facing Ryan at Colton’s mill and elsewhere was: What do we do now? How do we restore a river? How do we resolve the conflict between the laws of physics governing a river’s natural behavior with the need to protect homes, roads and businesses on the bank?

And how do we do all this given shortages of money, manpower and work days before winter?

‘Don’t fight the river’

The traditional Vermont response to flood damage has been to dredge out new gravel deposits and to keep water moving past private property by digging out a straight river channel with banks armored in stone.

Over the last 20 years, river scientists have learned that such “solutions” come with a cost and often do not work. At best, a channelized, armored river will need frequent maintenance. At worst, the river’s potential for damage will simply move downstream.

“The idea is you don’t want to fight to create a river channel that the forces of nature will constantly work against,” says Shayne Jaquith, the state’s river restoration scientist.

After looking at the Tweed, Ryan persuaded Colton not to insist on a quick, Band-Aid fix that would be unlikely to last. Then he won agreement from Colton, the state Transportation Agency and the town of Pittsfield to share the cost of some restoration.

Ryan hoped to resculpt 1,800 feet of river, giving it something close to the form, slope and dimensions the river would find, in time, if it were left alone.

If the design worked, the river would be stable, that is, powerful enough to move sediment downstream — one of a river’s jobs — but not so powerful it cut a deeper and deeper channel or collapsed its banks.

But “stable” in a river system doesn’t mean unchanging. Rivers naturally migrate across a valley landscape, eroding earth from the outside of bends, depositing dirt and stones on the inside of bends where water moves more slowly.

Compromise would be necessary. Here, as farther downstream, the Tweed could not be allowed to migrate willy-nilly because that would endanger the highway and buildings on its banks.

Meanwhile, across Vermont, river management engineers were facing dozens of similar situations — rivers used as gravel mines, landowners calling for new river channels to be moved away from their homes, anglers complaining about the destruction of fish habitat.

Winter loomed. Towns, already facing million-dollar road repair bills, were unable to undertake expensive river restoration projects. The state lacks sufficient staff to design and carry out multiple complicated restorations.

Compromise was required everywhere. Mike Kline, director of river management for the state, compared the dilemma to the building of a new home on a limited budget: The first priority is to get the superstructure right; interior details can wait.

“The basic work we could do was to get people to stop digging — stop digging an 80-foot-wide channel in a 30-foot-wide stream! We would redirect them to fill back in to get the dimensions of the channel right. Get that superstructure right. With that, the river can rebuild over time,” he said.

Resculpting a river

On the Tweed, Ryan had commitments for funding that he hoped would allow him to do a more complete restoration.

He and Jaquith assembled a survey crew to spend a day creating a topographical map of the river, measuring the width, depth and slope of the post-Irene channel.

They compared their measurements to what river science, and data about the Tweed watershed, indicated should be the stream’s natural dimensions. They also used U.S. Geological Survey data to determine how much “bedload” — gravel and sediment — the river should have the capacity to move downstream.

It was clear that big changes were needed.

At the point in the watershed where Colton’s mill sits, the Tweed’s channel should be about 45 feet wide and 2.5 feet deep, as measured from the top of one bank to the top of the opposite bank.

The post-Irene, post-dredging, channel was more than twice as wide and half as deep. The river had lost some of its bend, so it flowed at too steep a slope.

In the end, Jaquith designed a new path for the Tweed much like the one the river had chosen for itself in the years before Irene.

He called for the new channel cut by the river across the Grays’ field to be filled in. The ditch excavated post-Irene would disappear. Mathematical formulas determined the radius and frequency of three new bends that would send the river past the Grays’ house and Colton’s mill in a series of lazy curves.

Those meanders decreased the slope of the river, slowing down the force of the water. In one place, a bend would bring the river against immovable ledges on the far side of the narrow valley, a place where a good fishing hole might develop. Where another bend curved toward Colton’s mill, riprap would protect the bank from erosion.

The newly carved river channel would be 45 feet across. The rest of the 150-foot-wide gravel bed left after Irene would become the river’s new floodplain, a pressure relief valve to hold water during spring snowmelt and moderate floods.

At the tail end of November, the excavators went to work.

‘We’re 80 percent there’

As the heavy equipment finished its work on Dec. 2, the river landscape looked raw, as though newly scraped by a glacier. A wide expanse of gravel, the new floodplain, stretched up-river in the place of the Irene flood channel.

Out beyond the gravel plain, the river meandered gracefully back and forth across the valley within well-defined banks. Driftwood tree trunks had been anchored in the riverbank, their root systems sticking out into the water where they would absorb some of the force of the water and thus protect the banks from erosion. Rocks protected the stretch of shore beside Colton’s mill.

“In the end, I was satisfied,” the mill owner said last week, although he said it had been necessary for him to rein in the river scientists’ plans to import boulders to place in the stream to dissipate more stream energy and create fish habitat. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

“I paid my share, it got done and the river looks pretty good,” he said.

Jaquith and Ryan were satisfied they had done the best they could, within the constraints of an $11,000 budget and — ironically — a shortage of gravel to better define the channel edges at the far end of the 1,800-foot reach. Too much gravel had been dredged out of the waterway.

“What I saw there, that first day, was an ugly thing — I remember thinking, ‘How can someone do something like this to a river, even though it wasn’t done in malice?’ — but what came out of it I hope can be a model,” Ryan said last week.

“We restored a river in a collaborative way. All the parties responsible for the damage came together and did the right thing. We didn’t have to fine anybody or go through environmental enforcement. We have a better stream for stability, for protecting infrastructure, for fish.

“It wasn’t a perfect fit, but it was a good start,” he said.

Project aims to show crops, marshland can coexist for fish habitat and flood control

Paul Chinn / The Chronicle

A flock of birds flies over the Yolo Bypass near Woodland, where conservationists hope to restore ancient floodplains.

Woodland, Yolo County —

Five acres of mud and rice stubble doesn’t look much like fish habitat, but the rectangular patch of summertime cropland is in the process of being converted to a teeming marsh filled with young salmon.

The conversion to wetland of the rice paddy at Knaggs Ranch, north of Woodland next to the Yolo Bypass, is an experiment that conservationists hope will eventually lead to the restoration of ancient floodplains all along the Sacramento and San Joaquin River corridors.

The small piece of soon-to-be-flooded cropland is an attempt to combine agriculture with habitat restoration, flood prevention with the creation of more floodplain.

“There is a real push to just build levees higher and bigger rather than really taking into account ecosystem functions,” said Jacob Katz, a biologist with the Center for Watershed Sciences at UC Davis. “We are hoping to say, ‘Look, this is how you do it. You can protect against flooding this way, too.’ ”

Breaching levees

The experiment, which involves the breaching of levees protecting the lower 5 acres of a 1,700-acre rice farm, is one example of the kind of innovation that conservationists hope will be inspired by California’s first ever attempt to create a systemwide plan to manage floods.

The $4.9 billion FloodSAFE initiative, which was created by the Central Valley Flood Protection Act in 2006, involves an ambitious program to increase public safety, promote long-term economic stability and improve environmental stewardship in the areas that have historically flooded during winter rains.

The state Department of Water Resources will issue a draft of its flood protection plan on Dec. 30, to be followed by a public comment period and hearings. The Central Valley Flood Protection Board, a panel of experts appointed by the Legislature, will have until July 1, 2012, to adopt the plan.

Salmon and rice

The document will set guidelines for flood protection and funding along the Sacramento River and around the Yolo Bypass, which was built almost a century ago as a relief valve for Sacramento River flood water. The specific programs will be developed by local and regional governments and communities.

The Knaggs Ranch study is being conducted by UC Davis, the state Department of Water Resources and rice paddy owner John Brennan, with support from Cal Trout and Trout Unlimited.

The plan is to trap the floodwater over the next month and, on Feb. 1, introduce 10,000 to 20,000 juvenile chinook salmon captured from the Feather River. Marshland habitat, including native grasses, is being restored inside the 5-acre plot.

Biologists will study the fish, waterfowl and nutrients in the water to determine the health of the wetland and to see how well the rice straw breaks down. One concern, Katz said, is that too much rotting rice straw could suck the oxygen out of the water and kill the fish.

Testing the waters

The researchers want to determine the right biological mix and, in collaboration with the owner, expand the off-season wetlands project to cover the entire 1,700 acres.

The hope, assuming all goes well, is that access points would eventually be designed so that migrating salmon in the Sacramento River could enter restored floodplains throughout the 59,000 acres of agricultural land in the Yolo Bypass and elsewhere along the Sacramento-San Joaquin River Delta.

It is important because the delta, built to funnel water through the 1,300-square-mile confluence of the Sacramento and San Joaquin rivers, is the heart of California’s vast water network. The system of levees, dams, channels and pumps funnels snowmelt from the Sierra Nevada to 25 million people in the Bay Area, Central Valley and Southern California.

The network was designed not just to provide drinking water, but also to prevent the kind of epic flooding that once occurred regularly in the Central Valley. Flooding was so bad in the winter of 1861-62 that the entire Central Valley became a vast lake.

Flooded rice farms

The Yolo Bypass was approved in 1917 as an outlet for floodwaters every couple of years when the Sacramento River overtops what is known as the Fremont Weir. The land beneath the bypass, which is reserved for agriculture during the summer, becomes an inland sea during heavy flooding.

See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

Migratory waterfowl regularly visit the flooded rice farms and a small area of restored wetlands called the Yolo Bypass Wildlife Area. Sometimes juvenile salmon spill over the weir into the bypass, but the area is not designed for fish, which often become trapped, when the water subsides, and die in evaporating pools.

Staggering fish migration

It is one of many reasons fisheries biologists believe California’s once vast population of chinook salmon has been declining despite an enormous yearly infusion of hatchery-raised fish. Only about 5 percent of the original Sacramento floodplains still exist, Katz said.

The creation of a statewide flood management plan is an opportunity to restore the floodplains where migrating fish historically rested, foraged for food and fattened up before returning to the river, Katz said. It would also stagger the migration over the course of the winter and spring season.

“Floodplains are important for foraging fish and for creating a more diverse portfolio of life histories,” Katz said. “By taking away floodplains and channeling them into rivers, we have taken that diversity away.”

The original idea behind the FloodSAFE initiative was to shore up the system of levees in the delta, which have failed 166 times over the past 100 years. The danger of flooding is now worse than ever, according to experts, who point out that the sea level is rising and land in the Central Valley is subsiding.

The state’s flood management plan, which could cost as much as $16 billion to fully implement, is expected to include a major expansion of the Yolo Bypass.

“By expanding the bypass we open the door for increased ecosystem restoration while getting the dual benefit of reducing flood risk,” said Michael Mierzwa, the supervising engineer and flood policy adviser for the Department of Water Resources. “The caveat that I put on that is that it is going to take decades to implement.”

Commitment in spotlight

The level of commitment to ecosystem restoration is the major concern among many environmentalists. Many local community leaders are vehemently opposed to converting farmland into wetlands. One big reason, Mierzwa said, is because both the agricultural land and the product grown on it are taxable. When you take a rice farm out of production, he said, you reduce the tax revenues which are, in turn, used to maintain the flood system.

The Knaggs Ranch experiment, Katz said, is designed to show how floodplain and habitat restoration can be accomplished without taking agricultural land out of production.

“We’re really talking about a paradigm shift in the way we push water around the landscape,” Katz said. “It’s going to be much cheaper to invest in a system that incorporates floodplain restoration now than it will be in the future. It will be better for ducks, better for fish and better for farms.”

Lake Fork sportsmen and state work together to help create fish habitat

Members of the Lake Fork Sportsman’s Association partnered with the Texas Parks & Wildlife Department’s Inland Fisheries Division staff in making fish habitat improvements at Lake Fork last week.

They took advantage of drought-induced low water levels that have exposed shorelines and they planted 400 buttonbush plants around the lake.

Buttonbush is a native woody shrub commonly called “buckbrush,” and it was chosen to establish woody cover for fish.

When covered by water, it helps provide great bass fishing, a TP&W press release said.

Michael Rogge, president of the Lake Fork group, said approximately 15 members of the association and 15 members of the TP&W, spent approximately three hours planting 400 of the plants in two separate locations.

Rogge said the shrubs are adapted to “wet environments” like willow trees and that they will grow to about six to eight feet and be quite “bushy.”

“They will sprout new plants as seeds drop off,” in the future, and “become pretty dense,” which in turn creates fish habitat, he said.

Rogge said 200 of the plants were introduced in Glade Creek and another 200 in Big Caney.

According to a parks and wildlife spokesman, Lake Fork has had a long history of relatively stable water levels. This has been advantageous in that it has mostly translated into stable aquatic habitat and fish production. However, during the recent drought the disadvantage of this stability became evident. The lake elevation has dropped to an all-time record low, exposing shorelines and reducing cover which provides young fish shelter from predators.

The state said Lake Fork will likely be subject to more water level fluctuations in the future as the City of Dallas increases pumping operations on the lake, especially if the current drought persists.

In lakes where there are prolonged draw-downs, plants will grow in the newly expanded shoreline.

These include aquatic plants such as smartweed, sedges and rushes, along with a variety of other plants including shrubs and trees. Woody plants such as willows will grow rapidly along the shore, and when it rains and the lake elevation rises enough, the plants can become partially or totally covered.

The plants provide shelter for fish and for the establishment of many organisms that fish eat.

Some of the woodier plants are persistent and will survive for many years and provide benefits to the ecosystem.

The first step in this habitat enhancement plan materialized in March when the association purchased 1,000 bare-root buttonbush plants from a local tree nursery and planted them at selected locations throughout the reservoir. Survival of these small plants, most less than two feet in length, was low. At some of the planting sites they were trampled by feral hogs.

The second stage in the Lake Fork organization’s habitat project began to take shape this past summer. The opportunity to purchase larger plants presented itself when a fish farmer in Columbus, Texas, approached TP&WD looking for potential customers for 400 two-year-old buttonbush plants.

The TP&W press release said these larger plants should experience better survival. The LFSA agreed to underwrite the majority of the $1,900 purchase price, and TP&WD contributed $650. Bushes were planted at different elevations to hedge against future water-level changes.

The Radford Becomes a Reef Creating fish habitat

What was once a 553-foot Navy destroyer has become the East Coast’s largest artificial reef. This summer, as tourism and natural resources officials from Delaware, New Jersey and Maryland looked on, the new “reef,” slowly sunk to the bottom of the Atlantic Ocean. The Del-Jersey- Land reef, (named for the three states involved in the project) took about four hours to make its 138-foot descent.

The USS Arthur W. Radford’s final resting place is roughly 28 miles northeast of the Ocean City inlet, midway between the Indian River and Cape May. The Del-Jersey-Land reef is a cooperative venture between the three states to enhance fisheries habitat through decommissioned and retired ships, and railway and subway cars.

“It’s going to be a huge economic boost for Ocean City,” says Erik Zlokovitz, the artificial reef coordinator for DNR. “It is expected to attract bluefish, sea bass, weakfish, sharks and tuna, and that will attract charter fleets.”

The Radford was commissioned in 1977 and held a crew of more than 300. It patrolled Venezuela, Panama, Argentina, Brazil, Senegal, Oman, Bahrain, the Azores, Nova Scotia, Italy and Turkey. One of its final missions was deployment during Operation Enduring Freedom. The Radford’s homeport was Norfolk, Va.

The ship was named for Admiral Arthur Radford who served in three wars. He was onboard the USS South Carolina during World War I, in the Office of the Chief of Naval Operations during World War II and was Commander in Chief of the U.S. Pacific Fleet at the outbreak of Korean hostilities.

Taking nearly four hours to sink, the USS Radford is the largest ship to become a reef.

Montana gets $131,000 for fish habitat projects

Montana is among the states receiving funding for improving fish habitat. The U.S. Fish and Wildlife Service will provide more than $3.3 million to support 68 fish habitat projects in 36 states. An additional $9.9 million in partner contributions will go toward restoring and enhancing stream, lake and coastal habitat, as well as to improving recreational fishing and helping endangered species. The funding is provided by 15 Fish Habitat Partnerships. In Montana under the Western Native Trout Initiative, the state will receive $61,000 in Service funds and $70,000 in partner funds to restore 9 in stream miles in Four Mile Creek to benefit Yellowstone cutthroat trout.
