Key Projects Making a Difference
Northern Water is leading the way with cutting-edge projects that ensure a sustainable, reliable water supply for Colorado's future.
Colorado-Big Thompson Project
The Colorado-Big Thompson Project collects, stores and delivers more than 200,000 acre-feet of supplemental water each year. Melting snowpack in the Colorado River headwaters on the West Slope is diverted through a tunnel beneath the Continental Divide to approximately 1,064,000 million residents and 615,000 acres of irrigated farmland in Northeastern Colorado.

Windy Gap Project
Due to rapid population growth during the late 1960s, six Front Range communities formed the Northern Water Municipal Subdistrict in July 1970 to plan, finance, build and operate the Windy Gap Project. Windy Gap Project construction began in July 1981, was completed in 1985 and began delivering water to Municipal Subdistrict participants that same year. The project consists of a 255-acre-foot reservoir which collects water from the Colorado River downstream of the confluence with the Fraser River.
Northern Integrated Supply Project
Through the building of two new reservoirs, NISP will supply 15 water providers with 40,000 acre-feet of new, reliable water supplies.
Chimney Hollow Reservoir Project
As part of the Windy Gap Firming Project, Chimney Hollow Reservoir will provide water supplies for 12 water providers.
