Poudre Lake is an alpine lake and a main source of Poudre River. It is located just a few feet east of the Continental Divide in Larimer County, Colorado, United States.
U.S. Route 34 passes the lake and crosses the Continental Divide at Milner Pass at the southwest end of the lake.Fall River Pass, Colorado, 7.5 Minute Topographic Quadrangle, USGS, 1958 (1985 rev.)
It is a "dead lake", as fish cannot survive in it because it freezes completely during the winter months.
