Eyak lake weir culvert replacement

The Federal Highway Administration (FHWA) awarded The Eyak Corporation a $3.49M project grant under the Highway Planning and Construction program (CFDA 20.205) on June 16, 2025, for the Eyak Lake Weir Culvert Replacement project in Anchorage, Alaska. The project is scheduled for completion by September 30, 2028, and focuses on redesigning and constructing a stable, naturally functioning grade control structure at the lake outlet. The primary objectives include reducing downstream infrastructure risk, restoring aquatic organism passage to approximately 26 miles of anadromous habitat, maintaining lake levels to protect nearshore Sockeye spawning habitat, and improving Cutthroat Trout and salmon productivity within the watershed.

Project implementation and construction contract oversight and management are being conducted by the Copper River Watershed Project (CRWP), a non-profit environmental conservation organization based in Cordova, Alaska, which received a sub-award on September 5, 2025. The funding supports fish passage restoration through culvert modification, aligning with FHWA's broader infrastructure investment priorities that emphasize environmental compliance, ecological restoration, and multimodal transportation network improvements across the United States.
