Tri-Lakes Projects

Located near Denver, Colorado in the shadows of the majestic Rocky Mountains, the Tri-Lakes Projects are made up of the Cherry Creek, Bear Creek, and Chatfield dams and lakes.

The River Basin Balancer Game offers insight into an inland waterway and a system of reservoirs, which are operated with a goal for serving each of the benefits, flood control, navigation, hydropower, irrigation, water supply, recreation, fish and wildlife, and water quality, for which many USACE reservoirs are authorized and constructed. Users can take charge of river operations and experience the unique challenges presented when managing reservoir operations in a variety of weather conditions across a geographically diverse basin.
