Snow Lake Water Control Structure

The Bureau of Reclamation and the U.S. Fish and Wildlife Service (Service) released a draft Environmental Assessment (EA) for the proposed removal and replacement of the existing Upper Snow Lake tunnel water release control valve with a new valve. The water control 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 in the late summer, when cool, high-quality water is necessary for fish production and water is needed for irrigation. The new valve also will make it possible for the Icicle and Peshastin irrigation districts and the LNFH to use their 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 draft 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 December 21, 2017, through January 11, 2018 comment period for the Snow Lake EA has closed. Reclamation and the Service are in the process of compiling comments received during the comment period. Questions on the project may be directed to Mr. Stephen Kolk, Wenatchee Subbasin liaison, Bureau of Reclamation, 301 Yakima Street, room 319, Wenatchee, WA 98801-2966.
