(Healdsburg, CA) During the next week, construction will start on the first phase of a six-mile habitat enhancement project in the Dry Creek Valley. The purpose of the project, which is being conducted by the Sonoma County Water Agency (Water Agency) in cooperation with private landowners and by the U.S. Army Corps of Engineers (USACE), is to provide habitat for endangered coho salmon and threatened steelhead and Chinook. During the first phase of this multi-year project, an estimated 560 tons of boulders and 202 trees, root wads and logs will be used to create backwaters, side channels and shady habitat for the young fish that live in Dry Creek during the summer.

“This is a massive enhancement project that will provide big benefits for fish on the brink of extinction in our area,” said Sonoma County Supervisor and Water Agency Director Mike McGuire. “Dry Creek Valley farmers deserve tremendous thanks for their partnership and willingness to move this project forward.”

“We are excited to be starting construction on a project that should provide immediate help to the coho and steelhead raised at hatcheries at Warm Spring Dam and released into Dry Creek and its tributaries,” said Lt. Col John Baker, commander of the USACE San Francisco District. See the dozens of unique habitat models at fishiding.com

The habitat enhancement is required by National Marine Fisheries Service (NMFS) to help restore endangered and threatened fish to the watershed. The first phase of Dry Creek habitat enhancement involves two projects, as follows:

• The Water Agency Dry Creek Demonstration Project is centered on Lambert Bridge and is nearly one-mile in length. Construction in 2012 will take place at Quivira Winery and Vineyards. The Laytonville-based firm Bio-Engineering Associates is conducting the work at Quivira, which will be complete by mid-October. Work on the majority of the Dry Creek Demonstration Project will take place during 2013.

• The USACE project (known as the “Reach 15” project, for its location directly below Warm Springs Dam) is 1,400 feet long and is located on property owned by USACE. Contractor Services Group is overseeing construction which will take place through mid-October and during summer 2013.

Elements of the projects include bank stabilization to reduce erosion, boulders and anchored log jams to provide refuge and to slow the water, constructed backwaters and side channels to give the young fish places to escape summer and winter high flows, and native plants to reduce erosion and create shade.

“The habitat enhancements fit into Quivira’s holistic approach to grape growing and wine making. By improving Dry Creek, we improve the health of the land, helping both people and fish,” said Quivira Winery representative Ned Horton.

The majority of work on the Water Agency’s Dry Creek Demonstration Project will occur in 2013, and involves several landowners including Amista Vineyards, Dry Creek Vineyard, Rued Winery, Seghesio Family Vineyards and Yellow Dog Vineyards. The demonstration project also includes individual landowners Doug Lipton and Cindy Daniels, Carole and Geno Mascherini, Peter and Marian Van Alyea and Ron Wolmer.

When complete, the Dry Creek Demonstration Project and Reach 15 Project will serve as the first mile of habitat enhancement of the six miles required in NMFS’ Russian River Biological Opinion. The Biological Opinion was issued in 2008, and requires the Water Agency and the USACE to improve habitat for juvenile coho and steelhead in Dry Creek as an alternative to reducing summertime flows in the creek. (The high velocity of water flowing in Dry Creek in the summer was found by NMFS’ biologists to be detrimental to the survival of young coho and steelhead.)

“By breaking ground for this project the agency partners and landowners are reaching an important milestone on the road to conservation of our Russian River coho salmon and steelhead. This investment will not only benefit our fisheries, but is also an investment in the overall health of our watershed,” said Dick Butler, National Marine Fisheries Service.

Since nearly all of the 14-mile Dry Creek is privately owned, the required six miles of habitat enhancement is dependent on cooperative landowners. The demonstration project and the Reach 15 project will allow landowners, the Water Agency, the USACE, NMFS and California Department of Fish and Game to observe how enhancements work on a smaller scale.

“The coho broodstock program and stream enhancement projects in the Russian River watershed, including these important projects in Dry Creek, contribute greatly to coho salmon conservation. By enhancing and creating this habitat, we are improving conditions for coho and providing people more opportunities to enjoy and participate in coho habitat restoration successes,” said Scott Wilson, Acting Regional Manager, California Department of Fish and Game.

Dry Creek residents who notice any problems or who have immediate concerns regarding construction issues are urged to contact the Water Agency public information officer, Ann DuBay at (707) 524-8378, ann.dubay@scwa.ca.gov , or the USACE onsite engineer, Carlos Hernandez at (707) 431-4550 orCarlos.R.Hernandez@usace.army.mil.

Laytonville-based Bio-Engineering Associates specializes in construction of creek restoration and habitat enhancement features that also help reduce erosion. Several of the firm’s projects have been on major creeks located within vineyards.

Contractor Services Group, located in West Sacramento, is a full-service contracting company with experience in conducting large-scale restoration projects.

Dear friends,

I was recently contacted by J Harmon, President of the Protect lake Dunlap association in New Braunfels,Texas. He explained to me their struggle with the Guadalupe-Blanco River Authority over existing small diameter standing timber being hazardous to recreation use. Apparently, The GBRA has denied the cutting of these stumps to protect fish habitat and recommends marking these areas off to boat use which has the residents upset.

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

The PLDA’s plan is to draw down the reservoir and shorten the existing hazards about eight feet from normal surface elevation. I’m told there are hundreds of them and already have caused many accidents and property damage. J says the average depth is about 15 feet, so when cut, they would still stick up about 6-8 feet off the bottom, root ball intact.

After cutting, they plan to set one of our PVC habitat units on the remaining stump and fasten it there for good. This would increase the square footage of surface area approximately three times. The thinking is, with our units within six feet of the surface as water fluctuates, boats, skiers and water craft will be safe, including the fish. J and the group understand the benefits of not only keeping as much existing habitat as possible but to continue to add more habitat. The cut off tops would be kept and fastened to the remaining trunk too.

They have a full understanding of the science behind periphyton, nutrient removal and fish production and feel unwavering in their decision to work with only us in their efforts.

Senator Jeff Wentworth supports PLDA. With his intervention and the phone call from Gov. Rick Perry, GBRA’s action item #8 was tabled. The PLDA has been granted 30 days, (less now) to present their case for a final decision of what will be allowed. The General Manager and staff continue to meet with representatives of Lake Dunlap, enforcement officers, and fishery experts to evaluate the current no-wake area designation and alternative options to provide water safety and assure a balance of all uses including the preservation of fishery habitat and funding mechanisms, and to continue to review and develop alternatives that address congestion and lake boating conflict uses on Lake Dunlap and to report back to the Board at its next regularly scheduled meeting in August 2012.

What I’m asking of you once again is your opinion, hopefully your support. Can you find any adverse effects of removing these hazardous stumps as long as the habitat is replaced in other ways/forms? Can you comment on the benefits of the artificial habitat we produce and results you have seen? What can we expect to see in a 300 % increase in available cover for the fishery? With our help, the PLDA intends to present their plan for approval as a landmark decision for the state of Texas. Safety for the residents and fish is the priority of both sides, in that order. All parties involved want to save and increase fish habitat. Wood is good, just not where people get hurt. Send replies to either Jarod or myself at david@fishiding.com Thanks.

ES&E Magaqzine’s May/June 2012 issue

An enhanced floating treatment wetland (FTW) that incorporates air diffuser technology is under evaluation in an ongoing study at Floating Island International in Montana. The latest-generation system lifts and circulates water through floating streambeds within the FTW. This combination of FTW and improved water circulation/aeration is part of a product range called BioHaven®. The primary objective of the study is to determine whether biofilm-based microbes can provide nutrient removal, while increasing fish productivity.

This system, which is a new type of
constructed wetland, has been evaluated
for treatment of agricultural effluent and
municipal wastewater. Cost-effective treatment options for end users with limited
funding will be its greatest benefit. It can
provide treatment of agricultural-impacted
waters, municipal wastewater, storm water
and polishing of tertiary waste water, along with lake restoration.

Fisheries managers will be especially interested in the productivity potential afforded by a biological system, which can reduce algae and grow more (and bigger) fish. See the dozens of unique artificial fish habitat models, fish attractors and fish cover at fishiding.com, the leader in proven science based, fish protection.

Wetland areas have been reduced worldwide, while nutrient loading has increased
with growing human populations. Mass-production agriculture, as practiced in many developed nations, can contribute to hyper-eutrophication in water bodies that were previously low in nutrient concentrations. In fresh water, partly as a result of normal seasonal stratification, nutrient loading can deplete oxygen levels within the livable temperature zone for fish species.

Over the last 11 years, Floating Island
International (FII) has developed the Bio-
Haven FTW technology, which mimics
the ability of natural peat-based wetlands
to purify water. The Leviathan™ extrapolates
this technology by maximizing surface area and circulation, which are key components of wetland effectiveness. The islands are also designed to provide
optimal perennial plant habitat.

System background:
Dissolved oxygen and temperature measurements taken on Fish Fry Lake,
FII’s 6.5-acre research lake in 2008/2009 indicated that stratified water near the
surface was too warm to sustain a trout fishery. While temperatures below the
stratified warm water layer were sufficiently cool for trout, that zone contained
low dissolved oxygen (DO) levels. During late summer, no strata of water could
consistently provide the cold-water, high- DO environment demanded by fish, such
as rainbow, brown and Yellowstone cutthroat trout.
Groundwater containing variable nutrient concentrations enters the lake at an estimated average rate of 18 m3/hr. Surface water also flows into the lake with variable nutrient concentrations and flow rates. Evaporative loss and outflow are balanced to maintain the lake level, which is approximately 9 m deep.

As the lake was filled several years
ago, a series of BioHaven floating islands
covering 5,200 square feet (480 m2) of
lake area and providing over 9.3 ha of saturated surface area was installed. Several
islands were positioned next to the inflow
to maximize exposure to the highest nutrient concentrations.

These islands were designed to maximize production of biofilm (organisms attached to underwater surfaces), and to move nutrients into and through the food web.
After addition of the last 232-m2 FTW, floating islands now cover approximately 715 m2, or 2.7% of the lake’s surface area. Active treatment system with floating streambed Leviathan is an enhanced form of constructed wetland, and is FII’s latest effort to move excess nutrients into the food chain or harvest them. It integrates high volume, low-pressure circulation with matrix surface area constructed of postconsumer (recycled) polymer fibers, for maximum wetland performance.

Air-driven directional diffusers circulate up to 2,300 m3/hr, pushing it through the Bio-
Haven matrix and plant roots. The system’s floating streambed contributes to aeration and nutrient uptake.

The FPZ-brand air diffusers require 3 hp (2.2 kW) to operate, typically with 230V
single-phase power. Leviathan is designed to provide the  complete “wetland effect,” including aerobic, anaerobic and anoxic microbial nutrient conversion. This allows it to treat large, nutrient-rich stratified bodies of water, including “dead zones,” in both freshwater and marine settings. Removal of ammonia, nitrate, phosphate and soluble organic carbon has been demonstrated.

The system can move nutrients from
any depth into and through the islands’
biologically active substrate. In the
process, these nutrients are digested by
beneficial microbes and form periphyton
(attached plant and animal organisms
embedded in a polysaccharide matrix,
similar to biofilm), which is the base of
the freshwater food chain. As these excess nutrients transition into the food chain via biofilm/periphyton, both water quality and fish growth rates can be dramatically improved.
Leviathan can de-stratify water bodies, resulting in greatly expanded habitable zones for targeted fish species. As part of this process, high DO levels can be achieved and maintained, and water temperatures homogenized.

Results:
A 232-m2 Leviathan system, incorporating floating streambeds and grid-powered water circulation, was installed in the lake in April 2009. This system circulated up to 770 m3/hr through the stream channels within the island. Each cubic meter of Leviathan’s matrix, averaging 0.64 m in thickness, provided 820 square meters of surface area.

After 17 months of operation, water clarity had improved from a low of 0.36 m of visibility to as much as 3.3 m. Clarity is now at 5.8 m. Simultaneously, the
water temperature gradient was reduced, creating a larger zone of “livable” water for fish. Two age classes of Yellowstone cutthroat trout were introduced 13 and 14 months into the test. Through the summer of 2010, a favorable temperature/dissolved oxygen strata, ranging from the water surface down to a depth of at least 3.7 m, was maintained as potential cutthroat trout habitat.

One-year-old and two-year-old black crappie were also introduced two months
into the test, and naturally-occurring northern yellow perch were present in the
lake when it was filled. All three species have flourished.

The new aeration scheme in the lake improves water quality by incorporating
dissolved phosphorus and nitrogen into the aquatic food web, in the form of periphyton,
while limiting the growth of deleterious algae. Total phosphate concentrations
are reduced from about 0.04 mg/L to 0.02 mg/L, while nitrate-nitrogen
concentrations decrease from about 0.6 mg/L to 0.01 mg/L.
Fish Fry Lake is relatively unique in that it supports fish accustomed to cold
water (Yellowstone cutthroat trout), temperate water (perch) and warm water
(crappie). Montana officials have made two unsuccessful attempts at sustaining
cutthroat populations in an adjacent stretch of the Yellowstone River.
Fish catch rates and growth rates are now being monitored at the lake. Initial
data show that experienced fishermen catch an average of one perch every two
minutes. Visual observations from diving and an underwater viewing station indicate
that perch approaching or exceeding the Montana state record of 1.0 kg now
inhabit the lake.
The perch harvest at Fish Fry Lake averaged 12 kg of fish per week from May-
November 2011. With a phosphorus content of 0.9% in perch, phosphorus removal
from the lake via fishing averaged 0.10 kg/wk, or 84% of the estimated
phosphorus input to the lake.
In summary, Fish Fry Lake was poised to become another eutrophic waterway, until a new form of applied stewardship was introduced, which reversed the process.

A few weeks ago, my wife Renee’ and I took a trip to Shepherd Montana, headquarters of  Floating Island International Inc. We had been invited to stay on the ranch and to see for ourselves how Bruce Kania and his wife Anne, are growing huge fish fast with a woven matrix of inert substrates called BioHaven, or Floating Treatment Wetlands. I had been in contact with Bruce for some time, learning about how excessive nutrients brought in from runoff can be turned into fresh, tasty fish. Not only do the Kania’s grow fish, but frogs, minnows, pheasant, deer and all species of waterfowl prosper in their efforts. Even Yellowstone cutthroat trout flourish in this superior environment, along with crappie and perch and various minnows.

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

The setting was breathtaking, Mule deer and whitetail browsing on the thousands of perennial plants Bruce has planted for their benefit and soil stability. Over time these plants die off and return each spring, contributing to the rich organic soils being built up. Sprawling channels and wetlands run throughout the property, slowly beginning to filter and absorb the high levels of nutrients. When the water enters the property, it is dark and cloudy like chocolate.

Ducks of all varieties, geese, snipe, vulture, pheasant and more, have taken up residency in this oasis of prime habitat, with no intention of ever leaving. With Bruce being a veteran trapper, predators are being kept in check, protecting the desired species. With the Yellowstone River along one property line, this place is an outdoorsman’s paradise.

Stewardship of our natural resources is the core of the work being undertaken at Shepherd Ranch. We were there to catch and eat a bunch of these fish, helping them ultimately remove the phosphorus and nitrogen that causes excessive weed growth and poor water quality. Bruce and I dreamed big about someday soon, this concept of abundant, mass fish harvest to clean our Nation’s waters and beyond.

The data shows that over 50% of our Nation’s waterways are considered eutrophic and in trouble, meaning highly excessive weed growth and nutrient concentrations. Dark, stained and sometimes smelly water are all results of an unbalanced system. More information about our Nation’s waters are available on the National Fish Habitat Action Plan website, a wealth of details everyone is affected by.

When we began producing artificial fish habitat products made from reclaimed PVC siding called Fishiding, the ability to grow algae immediately on the inert surface area, appealed to the fisherman. Like myself, the average fisherman understands that habitat with good algae growth seems to hold more fish. It wasn’t until reading more and talking to Bruce that I began to understand the big picture of why this holds true.

These nutrients stick to surfaces underwater and create the beginning of the food chain called periphyton. Many forms of this wonderful natural, filter and food factory are present. Algae, bacteria, fungi, protozoa, zoo plankton and other invertebrates, function as a community highly efficient in capturing and processing nutrients. When I say processing, this means turning it into food of the highest quality found on earth. The more fish graze on it, it grows faster, decreasing bio mass and the fish grow at alarming rates, making the water clearer.

Numerous types of periphtyon are present, some require light to thrive and some do best in the dark. The more surface area available, the more periphyton can grow and work its magic. Pretend the floating island is a supermarket, the more shelves available the more food can be stocked for consumption. Small fish and fry eat this “super food” until about age one, when they begin to forage on larger minnows and bugs. Periphyton is the “mother’s milk” needed to start life full of nourishment.

This process has been perfected in second and third world countries. We are lacking in knowledge here in the states, but it’s improving with over 4400 of these floating treatment wetlands installed here and worldwide.

Think about all the ponds and lakes in your area. Golfcoarse ponds, retention ponds, private and public, there are many. Some are clear and deep with a balanced mesotrophic or oligotrophic eco system. The other 50% eutrophic waters, could be teaming with fish and every citizen is asked to help keep them clean…..by catching as many fish as you can eat, and removing them! The fish also reproduce faster than normal, so there is no worry of running out. Fish Fry Lake is living, thriving proof of this for all to see. Renee’ and I caught over 500 fish in less than eight hours of fishing. If your hook was in the water, it was being attacked by one or more gorgeous perch or crappie. From 6-8” one year olds, to 12-14” plus jumbos! Remember, this is in Montana not Lake Michigan, the only other place I have ever seen perch of this size. Perch and Crappie were abundant to say the least, with a perch containing about one percent live weight of phosphorus. The name “Fish Fry Lake” more than lives up to its name. Remember, this works with no chemicals, win,win,win…….

This natural cause and effect has other uses too. Bioswales also made by FII,  are used in ditches and swales to slow down erosion as water runs through it, similar to adding hay bales in a ditch after new construction. The difference in using the inert matrix, patented by FII, is that as the bioswales slow down the water, the periphyton forms and begins to consume the over abundant nutrients, cleaning the water as it passes through slowly. Unlike the hay bales, the matrix never breaks down, which would add to the nutrient load in the waterway. Same with weeds, as they decompose, they remove oxygen from the water and add fertile organic matter that acts like fertilizer. Inert substrates like the matrix material used in the Floating islands, never breakdown and keep working year round to feed the fish and clean the water.

One of the optimal ways that FTWs can transition nutrients from water to beneficial use is to grow bacterial biofilm rather than floating algae.  Bacterial biofilms grow faster than algae when their limiting parameters are satisfied, and when they have adequate circulation and surface area for growth.  With appropriate stewardship, they also are an improved primary food source for fish (Azim 2005).

Circulation increases bacterial efficiency by bringing nutrients such as dissolved oxygen, nitrogen and phosphorus to the biofilm.

A single 1000-square-foot BioHaven Floating Island can provide over 18 acres of strategic “concentrated wetland effect” surface area.

As demonstrated in field-scale case studies, waterways containing FTWs remove contaminants (pollutants) such as ammonia, total nitrogen, total phosphorus, Total Organic Carbon (TOC), Biochemical/Chemical Oxygen Demand (BOD/COD) and total suspended solids (TSS).  These studies have included municipal wastewater, storm water, lakes and agricultural runoff.  FTWs have demonstrated the ability to simultaneously remove all of these contaminants, due to their complex biofilms containing both aerobic and anoxic bacteria.

Dissolved oxygen (DO) levels are higher when inert substrate are used rather than organic substrates like wood, due to oxygen consumption during organic carbon uptake by biofilms.  Inert substrates like BioHaven polymer matrix, can provide a more precise ability to initiate movement of a waterway’s nutrient load up the food chain. Periphyton moves nutrients up the food chain better than does synthetic fish food.

The bottom line is this. To ultimately remove these unwanted nutrients, fish have to be harvested. Not all lakes have these issues, but in Eutrophic lakes, the fish contain these nutrients and have to be caught and eaten to keep up with the periphyton growth. A perch for example, contains about 1% live weight of phosphorus. By removing enough fish to equal one pound of this chemical which is safe for humans and needed for strong bones, about 700 pounds of aquatic vegetation never gets a chance to grow. No chemicals or weed harvesting just fishing and keeping them for the table. Would you be willing to help clean your neighborhood pond by catching and eating some fresh fish? It’s a reality and is being performed at an alarming rate at Fish Fry Lake. We flew home with only one checked bag, 50 pounds of fresh fillets.

Clean water  entering the Yellowstone River and ultimately the Mississippi, Stewardship is the lesson to be learned.
