Lewiston Dam, Embankment dam in Trinity County, United States
Lewiston Dam extends 745 feet across the Trinity River, forming a substantial reservoir with a storage capacity of 14,660 acre-feet of water.
The United States Bureau of Reclamation completed the construction of Lewiston Dam in 1963 as part of the extensive Central Valley Project water management system.
The Trinity River system, modified by the dam, holds importance for Native American communities who relied on these waters for generations.
The dam operates a power station that generates 3,335,000 kilowatt-hours of electricity annually while supporting irrigation needs in the Sacramento Valley.
The facility incorporates specific fish passage solutions to maintain salmon and steelhead migration patterns in the Trinity River ecosystem.
