CX-035041: Elk Creek Bridge Replacement

Bonneville Power Administration (BPA) proposes to fund the Nez Perce Tribe (NPT) to replace an undersized bridge across Elk Creek and a concrete sill on the stream bed with a larger bridge and no sill. Elk Creek is a tributary of the American River within the city limits of Elk City, Idaho (ID). The existing bridge backs up flows during high waters and introduces high amounts of sediment into Elk Creek. The sill is a fish passage barrier at low flows for Endangered Species Act (ESA)-listed Snake River steelhead and Columbia River Basin bull trout.
