Linderman Dam Restoration Project
In accordance with the National Environmental Policy Act, the Bureau of Reclamation has prepared a final Environmental Assessment for the Linderman Dam Restoration Project located within Teton and Fremont Counties near the town of Newdale, Idaho.
Linderman Dam was built in the late 1950s and was largely dismantled in 1972 for the construction of Teton Dam. After the 1976 failure of Teton Dam, the river resumed its previous course and the footings of Linderman Dam were exposed.
The structural remnants of Linderman Dam are composed of concrete that is eroded and vertical pipes that are exposed and protrude into the river flow. A horizontal concrete beam in the center of the dam still extends across the river at about the level of the water surface during average base-flow conditions. This feature creates a hazard to the recreating public floating on the river.
Reclamation proposes to perform construction activities necessary to ensure the safety of recreators on the Teton River. This project would consist of demolishing components of the Linderman Dam structure that protrude above the inundated concrete dam crest and constructing a natural riffle approximately 450 feet downstream of the existing structure. This would slow the flow of the channel and back water up to an elevation that would completely submerge the existing Linderman structure, effectively eliminating the hazard to the recreating public. Construction is tentatively scheduled for summer 2021. This project would eliminate the safety hazard, improve fish passage, restore the river to a natural environment and maintain upstream pool elevation for irrigation demands.
The proposal is analyzed and documented in the final Environmental Assessment issued in June 2020.
