The reservoir was created in 1950 when the Granby Dam was constructed across the Colorado River. The primary purpose of the reservoir is to provide water for irrigation, municipal, and industrial uses. The hydrology of the reservoir is dominated by snowmelt, and the surface flow is primarily from the Fraser River and other tributaries. The snowpack providers for the area include the Rocky Mountains, which are a primary source of snow and rainfall. The reservoir also supports recreational activities like fishing, boating, and camping. In recent years, the reservoir has experienced some challenges due to drought and low snowpack levels, which have impacted agricultural and recreational activities.
