Boulder Reservoir is located in the northern part of Boulder, Colorado. It stores water for the Northern Colorado Water Conservancy District — also called Northern Water — and for the City of Boulder. The reservoir is the centerpiece of the Boulder Reservoir Regional Park, which is managed by the City of Boulder's Department of Parks and Recreation.
The reservoir receives most of its water from Colorado's Western Slope through the Alva B. Adams Tunnel and the Boulder Feeder Canal, both part of the Colorado-Big Thompson Project.[3] Some of the stored water is used as part of Boulder's municipal water supply and some is used for agricultural purposes in Boulder and Weld counties.
