Fish and Aquatic Conservation

Projects

The National Fish Passage Program has a strong record reconnecting our nation’s rivers. The Program has resulted in the removal of over a thousand barriers, restoring more than 20,000 miles of stream access and 155,000acres of wetlands. NFPP project types include culvert replacement, dam removal, build bypass, construct low-water crossing and install fish ways and fish screen in cooperation with State and Federal agencies, non-governmental organization, universities and individuals.

Dam Removal

Marshfield Dam Removal, Winooski River, Marshfield, VT
In 1999 a fish kill eliminated the brook trout community for five miles upstream of the Winooski River. This will reconnect the 4 miles above the derelict dam with the 15 miles of downstream of the dam.

Culvert Replacement

Replace Prosperity Road crossing on Little Niangua River to benefit threatened Niangua darter. This location is a key component of improving fish passage and habitat stability in a significant portion of federally designated critical habitat.

Fish Screen and Water Diversion

BQ diversion and fish screens on Twin Creek in Wyoming. This project benefits water users as well as providing fish passage and saving 10's of thousands of fish annually in the system. During 2008 Trout Unlimited operated a fish trap , a total of 402 fish (all native species), including 1 Bonneville cutthroat trout, 15 northern leatherside chubs, and 2 bluehead suckers. In addition we captured 5 longnose dace, 132 redside shiners, 178 mountain suckers, 23 speckled dace, 45 Utah suckers, and 1 sculpin.

Fishway

Red River Fish Passage at Christine and Hickson Dams in Minnesota and North Dakota

Fish passage was identified as a major component to the success of lake sturgeon restoration in the Red River watershed and on the White Earth Reservation. Christine and Hickson dams were 2 of 3 remaining mainstem dams that prevented fish from freely migrating upstream to access spawning habitat in the upper Red River.

Dike and Levee removal in the Lower MS River - Kangaroo Point

The project will directly reconnect 41 acres of active floodplain habitat to the Naches River and will reconnect 2 side channels that were cut off by the original levee construction in 1974.
