CHEYENNE – Because of higher than normal flows expected sometime this week in Douglas Creek, the City of Cheyenne Board of Public Utilities expected Rob Roy Reservoir to fill on Friday.
Douglas Creek, located in the Medicine Bow Range, supplies the reservoir, which is one of six water supply collection locations for the City of Cheyenne.
When the reservoir fills, a spillway safely and naturally drains additional water back into Douglas Creek, resulting in the flow increase.
BOPU officials recommend those living near or visiting Douglas Creek exercise caution and be aware that flows may rapidly change depending on weather conditions.
As of Thursday, Rob Roy Reservoir contained 35,159 acre-feet of water – about 98.7% of capacity. Since one acre-foot equals 325,851 gallons of water, at full capacity Rob Roy can hold 11 billion gallons of water.
For perspective, 11 billion gallons of water would fill 405,876 school buses.
As the Capital City’s lone water provider, the Board of Public Utilities manages, monitors and protects Cheyenne’s water quality, storage and delivery systems.
The Board also oversees the engineering, design, construction and maintenance of Cheyenne’s water and sewer infrastructure.
