Environmental Impact Statement - Moffat Collection System Project

Summary: The Denver Water Board requested a Section 404 Permit (Clean Water Act) from the U.S. Army Corps of Engineers, Omaha District Regulatory Branch to enlarge the existing Gross Reservoir (near Boulder, Colo.) to supply 18,000 acre-feet per year new firm yield of water to its Moffat Collection System. The Corps is the lead federal agency and has been preparing an Environmental Impact Statement since 2003 to analyze environmental effects. Water supplied to the Moffat Collection System is proposed to be diverted from either West Slope tributaries of the Colorado River or from the South Platte River in the Colorado Front Range. Denver Water's preferred project is to enlarge Gross Reservoir in Boulder County to provide storage for the diverted water.
