CHEYENNE, WYO. – The City of Cheyenne says that People living or visiting near the Douglas Creek area, located in the Medicine Bow Range, should expect higher than normal flows in the Douglas Creek and surrounding riverways due to excess runoff from an above-average snowpack this year.

According to City Officials, Rob Roy Reservoir, one of six reservoirs supplying water for the City of Cheyenne Board of Public Utilities (Board), is expected to fill around Thursday, May 21, 2020.

“Based on the predicted forecast, increased snowmelt in the surrounding area will continue to flow into the Rob Roy Reservoir causing the reservoir to fill. Once full, a spillway will safely direct natural runoff water flowing into the reservoir back into Douglas Creek, resulting in the higher than normal flows.,” the City said via media release.
