(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.

KEENE VALLEY – At last. The Rivermede Project – officially known as the East Branch Ausable River Restoration Project at Rivermede – is essentially done.

For a long time, this half-mile stretch of river in Keene Valley was growing broader and shallower, filling with sediment and gravel as its banks eroded and fell in, eating the land of Rivermede Farm at a rate of several feet a year and losing habitat for fish, amphibians and reptiles.

Beginning in July, 2012, large trees were dug out of the ground nearby and imbedded in the riverbank, root wads facing into the stream as fish habitat, the trunks buried side by side to stabilize the bank.

Carl Schwartz, of U.S. Fish & Wildlife Service, leads a tour of the recently completed Rivermede riverbank stabilization and restoration project on the east branch of the Ausable River in Keene Valley Thursday, Aug. 16.

“Fish, llittle minnows and bigger fish, appeared immediately, as soon as the habitat was restored,” said Corrie Miller, director of the Ausable River Association.

At the toe of the bank, underwater, where they will not decay, logs are buried, covered with a layer of woody debris and fill, live cuttings, and then a sod mat of jute or similar material, for the cuttings to grow through. This constitutes a bench, which deflects water currents, preventing scouring of the bank.

As plant life grows, it will stabilize the bank further. Every boulder, natural as it looks, was scientifically placed to maneuver the current just so, preventing scouring of the bank and moving the water, and sediment, in a way that benefits the river and its environs.

Riverbank stabilization experts used to think it was all about water dynamics.

“Now we know it’s also about sediment being moved and deposited,” Miller said.

Flood plain room is allowed for seasonal overflow of water and sediment; floods cannot be prevented, nor can they be contained or controlled with straight channeling.

“We want to make it look as if we were never here,” Schwartz said.

Miller said that willow shoots were planted to stabilize the bank, and started sprouting leaves right away. Willows root easily and quickly along a riverbank. More plantings will be made next spring, she said.

According to Braico and Schwartz, this design has a better chance of holding than older, less natural methods. Everyone concerned seemed to be crossing fingers that another major weather event will not take place before this restoration settles in and takes hold.

Thursday, Aug. 16, two days after completion, tours were held at the site to explain what had been done to restore natural riparian (riverbank) equilibrium. About 80 people attended the tours.

Rob Hastings, Rivermede farmer, who has contributed time and money to the effort over the years, was present. He expressed his happiness that the project is done and that the river looks so beautiful, as well as his hope that it will hold.

Instruction was given by John Braico of Trout Unlimited and Carl Schwartz of F&W. Corrie Miller, Director of the Ausable River Association, Tonnie Sauca, standing in for David Reckahn of Essex County Soil and Water Conservation District, and Martha Naley, of F&W, were also helpful in explaining the project and the science behind it to participants.

The Keene Town Board, represented by Councilman Paul Martin, presented Braico with a plaque in recognition of his years of service and extensive volunteer work on this project.

Former Keene Supervisor Tom Both, who presided over the early planning days of the “Rivermede Project,” praised Braico at the August town board meeting, stating that Braico has “devoted thousands of hours to this project over 15 years.”

In 1998, Trout Unlimited began initial studies of the problem.

The Army Corps of Engineers became involved with the project in 2005, then finally withdrew in 2012 because the town could not come up with sufficient funding for the Army Corps plan. That same month, Trout Unlimited approached U.s. Fish & Wildlife Service, asking to partner with them to do a different version of the stalled 15-year project within a modest budget.

Between July 14 and August 14, 2012, inside 23 work days, under the direction of US Fish & Wildlife Service and Trout Unlimited, Ward logging LLC, under Michael Ward, harvested and staged whole trees, logs and boulders from the Rivermede area and performed active construction. Seeding and mulching was done by TU, F&W and Essex County Soil and Water Conservation District.

There is no riprap at this site. All materials are from the neighborhood, following a healthy, natural river model. According to Trout Unlimited information, extreme floods are increasing in frequency, and methods including dredging, straightening, laterally confining, vertically entrenching and overwidening stream beds are unstable and can cause destruction to roads, bridges and buildings in major floods.

As an example, containment of the Ausable’s East Branch at its present width of 176′ would entail dredging to 19.4,’ according to TU statistics.

With unpredictable weather patterns that have been bringing frequent “100-year storms,” probably everyone in town is, like Rob Hastings of Rivermede, thankful and at the same time hoping it will work.

Funding for the project was provided primarily by The Adirondack Chapter of trout Unlimited, U. S. Fish & Wildlife Service and Essex County. Additional financial support was provided by Trout Unlimited of Tri Lakes, Lake Champlain and New York City, as well as Rivermede Farm, the town of Keene and the Ausable River Association.MARTHA ALLEN , Lake Placid News

Fish from ponds and ditch now accounts for 41 percent of total yearly production of 30.61 lakh tonnes.

A decade ago, its contribution was 34 percent, according to the Department of Fisheries (DoF).

Contribution of fish caught from rivers fell to 34 percent in fiscal 2010-11.

Declining fish habitat, the ongoing destruction of juvenile fish by using monofilament synthetic nylon fibre net and mosquito net, and environmental pollution are the major reasons behind the falling supplies of fish from rivers.

“An increased production and availability of fingerlings and hatchlings because of growth in hatcheries has played a key role in expansion of fish farming,” said Krishnendu Saha, chief fisheries extension officer of the DoF.

Over the past two decades, private investors established more than 800 fish hatcheries.

Their interest grew due to a business prospect against the backdrop of falling catches in open water areas and rising demand for fish.

Initiatives by the government and NGOs to motivate farmers also facilitated farming for common carp, pangus, monosex tilapia and shing (cat fish) in regions such as Mymensingh, northern districts, Jessore and Comilla.

Saha said many people in these areas entered freshwater fish farming because common carps (ruhi, katla, silver carp), pangus and tilapia become marketable in a short time.

It enables the farmers to gain higher profit from fish than growing crops such as paddy and jute, he said.

“Many people in greater Mymensingh have started fish culturing by making ditches in crop fields,” said Saha.

According to the DoF data, total pond area under fish farming was 2.42 lakh hectares early this decade, and such areas rose to 3.96 lakh hectares in fiscal 2010-11.

Production also rose to 12.70 lakh tonnes in 2010-11 from 11.40 lakh tonnes a year ago.

In fiscal 1999-2000, total production of fish from pond was 5.61 lakh tonnes, according to the DoF.

Sajjad Hossain, managing director of Joyda Aquafarm Ltd, said many people are engaged in pangus farming because it needs low investment.

Technologies were also easy for the farmers to follow, said Hossain of Joyda, which produces pangus fries at hatcheries, cultures those and sells to market.

The company produces 2,500 tonnes of pangus a year, he said.

M Mahfujul Haque, a professor of the Department of Aquaculture of Bangladesh Agricultural University, said the country has a huge potential to expand fish farming as only 11 percent of its pond resources have so far been exploited for fish.

In the past, fish was cultured in ponds by collecting hatchlings from natural sources. But the main breakthrough came since the beginning of artificial propagation, he said.

“Large investments have come in fish farming and some farms have gone for vertical integration,” said Haque

He said expansion of fish farming created job opportunities for many and augmented incomes of farmers. Some 25 types of jobs have been created because of fish farming, he added.

“The socio-economic impact of fish farming is huge,” said Haque, adding that many educated people entered such a farming failing to get jobs in the formal sector.

However, challenges are increasing. See the dozens of unique artificial fish habitat models at fishiding.com, the leader in true fish protection.

“Fries are not growing fast nowadays like the past. Inbreeding is also widespread,” said Hossain of Joyda Aquafarm.

At the same time, productivity of ponds is declining because of continuous farming in the same ponds.

“But production costs are rising because of soaring feed prices and other costs. It reduces profit margins,” he said.Sohel Parvez
