Heavy rain and mountain snowmelt runoff since the beginning of May have produced high flows along the South Platte River in Colorado and its contributing tributary streams. The three Denver-area dams operated by the U.S. Army Corps of Engineers, Omaha District and referred to as the Tri-Lakes Projects are Chatfield, Cherry Creek, and Bear Creek Dams.
These three reservoirs have captured a combined 25,000 acre-feet of flood water during this period. The combined storage capacity of these three reservoirs is nearly 314,000 acre feet of water.
