Shadow Mountain Reservoir is a man-made lake in Grand County, Colorado, created in 1947 by the construction of a dam on the Colorado River. It has a capacity of 33,000 acre-feet and is used for hydroelectric power generation, irrigation, and recreational activities. The reservoir is fed by snowpack in the surrounding mountains and surface flows from the Colorado River and its tributaries. The Colorado-Big Thompson Project and the Windy Gap Project are the primary surface flow and snowpack providers to the reservoir. The water from Shadow Mountain Reservoir is used for irrigation of crops such as hay and potatoes in the surrounding farmland. Recreational activities such as fishing, boating, and camping are popular in the area.
