BOPU 5-26, 2016
People living near or visiting the Keystone area in the Medicine Bow Mountain Range should expect higher than normal flows in Douglas Creek starting around May 26, 2016.
With this year above average snowpack, the City of Cheyenne Board of Public Utilities (BOPU) is expecting a larger than normal flow in Douglas Creek. Douglas Creek supplies Rob Roy Reservoir which is one of six water supply reservoirs for the City of Cheyenne. The BOPU expects Rob Roy Reservoir to fill around May 26, 2016.
Once the reservoir fills, a spillway will safety and naturally spill additional water coming into the reservoir back into Douglas Creek, resulting in higher than normal flows in Douglas Creek. With a higher than normal snowpack, flows in Douglas Creek and surround areas could be heavy for several weeks. People living near or visiting Douglas Creek should exercise caution and be aware that flows may rapidly change depending on weather conditions.
As of May 24, 2016, Rob Roy Reservoir contained 35,252 acre-feet of water, or approximately 98.9 percent of capacity. Since one acre-foot equals 325,851 gallons of water, at full capacity Rob Roy can hold 11 billion gallons of water.
