Lake McCloud is a reservoir on the McCloud River in Northern California. The lake forms behind an earthen dam finished in 1965 by the Pacific Gas and Electric Company to control water flows and for generating hydro-electric power. McCloud Dam (National ID # CA00416) is 235 ft high, 630 ft long at its crest, and impounds a maximum capacity of 35200 acre-feet. The lake is home to a population of rainbow and brown trout, due in large part to the fact that the lake water temperature stays relatively cold all year.
