About the Boulder Reservoir

The Boulder Reservoir is a 700-acre, multi-use recreation and water-storage facility, owned and managed by the City of Boulder and operated as a water supply by the Northern Colorado Water Conservancy District. It is used for recreation, drinking water and irrigation. Popular recreation activities at the reservoir include boating, swimming, sun bathing, water skiing, fishing, picnicking, walking, running, cycling and wildlife viewing.

We want to hear from you!

We’ve just wrapped up the summer season at the Boulder Reservoir. If you’ve visited the Rez this summer, let us know how it was and how we can make it better by taking a survey.

The survey will be open through Tuesday, Oct. 5. Thanks for your feedback!
