Environmental Impact Statement - Northern Integrated Supply Project

Summary: 

The Northern Colorado Water Conservancy District (Northern) provides water and operates infrastructure that serves numerous communities along the Front Range of Colorado. Northern, acting on behalf of 15 municipal and rural domestic water providers (Participants), requested a Clean Water Act Section 404 Permit from the USACE Omaha District Regulatory Branch to undertake the Northern Integrated Supply Project (NISP). The proposed project would provide 40,000 acre-feet of new reliable water supply, which would meet a portion of the Participants' future water supply needs. The project proposes the construction of two new reservoirs, Glade and Upper Galeton, with capacities of 170,000 and 45,624 acre-feet, respectively. The USACE is the lead federal agency and has been preparing an EIS since 2004 to analyze environmental effects. More than 200 potential water storage facilities and 16 potential water supply sources were evaluated with four project alternatives being carried forward in the EIS.
