Environmental Impact Statement - Windy Gap Firming

Summary:

The Municipal Subdistrict, Northern Colorado Water Conservancy District (Subdistrict) requested a Section 404 (Clean Water Act) Permit from the USACE Omaha District Regulatory Branch to construct Windy Gap Firming Project Water Supply facilities for its customers and 13 other Front Range water providers located in Colorado between Denver and Fort Collins. The U.S. Bureau of Reclamation (USBR) is the lead federal agency managing the EIS for the project since 2003, and the Omaha District Regulatory Branch has been participating as a Cooperating Agency. The project captures water from the Colorado River, pumps it to existing reservoirs on the west slope and moves the water through a tunnel system (the Colorado-Big Thompson Project operated by Reclamation) to the Front Range of Colorado. The project proposes to construct Chimney Hollow Reservoir, west of Berthoud, Colorado.

The USBR is the lead federal agency managing the EIS for the project, documents related to this project are available at: http://www.usbr.gov/gp/ecao/nepa/windy_gap.html
