All about Horsetooth Reservoir Fort Collins, CO

Horsetooth Reservoir - Fort Collins CO

Horsetooth Reservoir (locally known as Horsetooth) is a large reservoir in southern Larimer County, Colorado, just west of the city of Fort Collins, Colorado. The reservoir sits in the foothills above the town on the western side of the Dakota Hogback, which contains the reservoir along its eastern side. The reservoir runs north-south for approximately 6.5 miles and is approximately one-half mile wide. It was constructed in 1949 by the Bureau of Reclamation as part of its federal Colorado-Big Thompson Project or "C-BT". 

The average temperature in Horsetooth is colder than most comparable lakes in the area because the water comes through the Colorado-Big Thompson Project pipeline from a very cold Grand Lake.

The Horsetooth Dam closes the northern end of the reservoir, with a height of 155 feet.  

Horsetooth is approximately 1900 acres and provides quality fishing for walleye, smallmouth bass, Rainbow and Cut-bow trout. Anglers may also catch white bass, crappie, bluegill, and perch.
