Horsetooth Reservoir (Natural Resources)

West of Fort Collins

Six and one-half miles of water beckon visitors to come out and play! Surrounded by 1,900 acres of public lands, this reservoir has it all: fishing, boating, camping, picnicking, swimming, scuba diving, rock climbing, and water skiing.

As part of the Colorado-Big Thompson Project to divert water from the west slope to the east slope for drinking water, irrigation, and hydropower generation, the reservoir is jointly operated by the Bureau of Reclamation and the Northern Colorado Water Conservancy District who manage water levels for irrigation, municipal, and industry use. Larimer County manages recreation.

Horsetooth Reservoir requires entrance and camping permits, and is open year round. It's located west of Fort Collins, Colorado, at an elevation of 5,420 feet.
