The Greybull Valley Irrigation District proposes to construct an off-channel dam and reservoir to supply irrigation water to farmers in the lower Greybull River Valley. Three alternatives were evaluated: the proposal (Lower Roach Gulch Reservoir), the Blackstone Gulch Reservoir and the No Action Alternative. The Environmental Impact Statement discloses potential environmental impacts from implementation of the alternatives. The Draft Environmental Impact Statement (DEIS) was made available to the public in January, 1997 with a 60 day comment period ending on March 18, 1997.
