Connecticut River American Shad Monitoring

American Shad

Massachusetts Division of Fisheries and Wildlife (MassWildlife) and the U.S. Fish and Wildlife Service (USFWS) recently completed a third year of cooperatively monitoring juvenile American shad in the Connecticut River.

Biologists collect data on abundance, length, and weight to assess the growth, survival, and productivity of the population.

This study is designed to help determine the impacts of dams on juvenile American shad. 19th century dams prevent adults from migrating upriver to find spawning habitat, contributing to the decline of the iconic species.

Young shad are a food source for smallmouth and largemouth bass, walleye, perch, and northern pike. Shad also provide food for birds and terrestrial mammals, as well as marine fish including striped bass.

While surveying the river, biologists captured an array of fish species. In addition to American shad, they captured a 25'' walleye, 35'' carp, and 19'' smallmouth bass.

Snake River Headwaters Restoration

Trout Unlimited (TU) and Jackson Hole Trout Unlimited (JHTU) recently announced the launch of an ambitious new initiative to restore and protect the headwaters of the upper Snake River and its fishery, together with a diverse group of community and agency partners.

 TU’s Snake River Headwaters Home Rivers Initiative will leverage the capacity of the active JHTU chapter and engaged membership in and around Jackson Hole by working with partners to develop and implement high-priority restoration projects to benefit native trout and their habitats.

The Snake River Headwaters HRI will reconnect native trout spawning and rearing habitat by installing fish screens and removing fish passage barriers.

Projects will also restore water quality, habitat, and healthy stream conditions by improving water use and restoring streamflows. Outreach and youth education will actively engage the community and partners in these efforts.

The Snake River Headwaters HRI has been funded by a $100,000 commitment from JHTU as well as the generous support of other private donations.

Idaho Dutch Flat Dam Removal Could Benefit Steelhead

Dutch Flat Dam was a 10-foot barrier built nearly a century ago to provide drinking water to Troy, Idaho. The dam spanned the West Fork of Little Bear Creek, which ran so dry in summer that nobody thought steelhead survived there.

About a decade ago biologists realized that steelhead do, in fact, survive in such streams. It turns out that steelhead are able to survive dry periods by moving into pools cooled by underground flows.

Over the summer of 2013, local leaders and the Idaho Department of Fish and Game worked with federal agencies to take out the dam so steelhead can again move freely up the West Fork of Little Bear Creek. Crews finished removing the dam’s concrete in early September and are now widening a new course for the creek.

An inventory by Idaho Fish and Game about 10 years ago surprised many locals by finding steelhead throughout the Potlatch River drainage in small streams such as Little Bear Creek that mostly dried up in summer. It turned out that the fish survive the summer in remnant pools cooled by subterranean water.

As word of the steelhead spread, so did enthusiasm for removing the dam and reopening the West Fork of Little Bear Creek, said biologist Bob Ries of NOAA Fisheries. Enthusiasm grew even more when a local resident found steelhead spawning in the creek.

Biologists salvaged almost 180 fish from pools below the dam before the removal began and about three quarters were steelhead, Johnson said. It was the most steelhead they had ever captured in that reach, he said, suggesting that many fish stand to benefit from removal of the dam.

Snake River steelhead were listed as threatened under the Endangered Species Act in 1997. Removing migration barriers and restoring access to high quality spawning and rearing habitat is considered critical for their recovery.

NOAA Fisheries and the Bonneville Power Administration provided $500,000 for the project. NOAA’s funding came from the Pacific Coastal Salmon Recovery Fund, a competitive grant program dedicated to restoring Pacific salmon and their habitat.
