Carter Lake
Three miles long and about one mile wide, this beautiful 1,100-acre reservoir is surrounded by 1,000 acres of public lands. It’s a great place for fishing, sailing, water skiing, camping, picnicking, swimming, scuba diving, and rock climbing.
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.
Carter Lake requires entrance and camping permits, and is open year round. At 5,760 feet in elevation, it is nestled in the foothills southwest of Loveland, Colorado, and northwest of Berthoud, Colorado.
