About the Project:

The Numana Dam is a Pyramid Lake Paiute Tribe agricultural diversion structure structure
Something temporarily or permanently constructed, built, or placed; and constructed of natural or manufactured parts including, but not limited to, a building, shed, cabin, porch, bridge, walkway, stair steps, sign, landing, platform, dock, rack, fence, telecommunication device, antennae, fish cleaning table, satellite dish/mount, or well head.

located 8 miles above Marble Bluff Dam. The dam severely restricts migration of endangered Cui-ui and threatened Lahontan cutthroat trout from Pyramid Lake to historic spawning habitat upstream of the Derby Dam. The Pyramid Lake Paiute Tribe has supported modification to Numana Dam for over two decades in support of recovery of Cui-ui and Lahontan cutthroat trout. The reestablishment of the iconic native strain of Lahontan cutthroat trout in the Truckee River basin has garnered support from the Bureau of Reclamation, the Nevada Department of Wildlife, and the angling community, and is culturally significant to the Pyramid Lake Paiute Tribe.  BOR invested $37 million to construct a fish screen at Derby Dam that, for the first time in 85 years, will allow operation of a fishway to connect the lower Truckee River at Numana Dam to 65 miles of LCT spawning habitat. 

The National Fish Passage Program combines technical expertise with a track record of success. 

Implemented primarily through the Service's Fish and Wildlife Conservation Offices, the National Fish Passage Program provides financial and technical assistance to partners across the country. Since 1999, the program has worked with over 2,000 local communities, Tribes, and private landowners to remove or bypass over 3,400 barriers to fish passage and reopen access to over 61,000 miles of upstream habitat for fish and other animals. Staff have expertise in fish migration and biology as well as financial, engineering, and planning assistance to communities, Tribes, and landowners to help them remove barriers and restore rivers for the benefit both fish and people. 

Fish passage project proposals can be initiated by any individual, organization, government, or agency. However, proposals must be submitted and completed in cooperation with a Fish and Wildlife Conservation Office. (Please note that fish passage projects being used for federal or state compensatory mitigation or required by existing federal or state regulatory programs are not eligible for funding through the National Fish Passage Program.) 




The Fish Passage Program works with local communities on a voluntary basis to restore rivers and conserve our nation’s aquatic resources by removing or bypassing barriers. Our projects benefit both fish and people.
The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
