Snow Lake Water Control Structure

The Bureau of Reclamation and the U.S. Fish and Wildlife Service (Service) have issued a final Environmental assessment (EA) and Finding of No Significant Impact for the proposed removal and replacement of the Upper Snow Lake water release control valve. The water control valve structure is located on land owned by the Service surrounded by the Alpine Lakes Wilderness Area in Chelan County, Washington.

The existing valve has exceeded its expected 10-year service life and cannot reliably meet the 80 cubic-feet-per-second release capacity needed by the Icicle and Peshastin irrigation districts and Leavenworth National Fish Hatchery (LNFH) in the late summer, when cool, high-quality water is necessary for fish production and to meet irrigation demands. The new valve also will make it possible for the Icicle and Peshastin irrigation districts and the LNFH to use their respective water storage contract and water right in Snow and Nada lakes to meet their mission and provide additional water to benefit fish, wildlife, and habitat resources in Icicle Creek. Reclamation and the Service have prepared this EA to evaluate the environmental impacts of the proposed action ─ removing and replacing the valve, including the means to transport materials, equipment, supplies, and contract personnel to the remote location ─ and reasonable alternatives.

The activities of the preferred alternative described in the EA will occur in fall 2019.
