This quiet, 47-acre reservoir is surrounded by 200 acres of public lands. It's a popular spot for fishing, picnicking, and family camping. Swimming and boating are not allowed here, but nearby Carter Lake offers both!
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.
Flatiron Reservoir requires entrance and camping permits, and is open year round. At 5,470 feet in elevation, it is a few miles northwest of Carter Lake, southwest of Loveland, Colorado, and northwest of Berthoud, Colorado.
