Boulder's Reservoirs 

Barker Reservoir

Barker Reservoir, located on Middle Boulder Creek, is owned by the City of Boulder. Water from Barker Reservoir is treated, along with the Silver Lake Watershed supply, at the Betasso Water Treatment Plant. The Betasso plant is Boulder’s primary water treatment plant and is located in the foothills west of Boulder. Learn more information on the city’s management plan for Middle Boulder Creek and Barker Reservoir.

Boulder Reservoir
Boulder Reservoir, located northeast of Boulder, was constructed by the city to provide another source of drinking water. Boulder Reservoir has also become a popular recreation site. Boulder Reservoir is owned by the City of Boulder, but is operated by the Northern Colorado Water Conservancy District (NCWCD). The NCWCD operates the Colorado-Big Thompson (CBT) Project and the Windy Gap Project. These two projects divert water from the upper Colorado River on the western slope and deliver it, through a series of tunnels, canals and reservoirs to north-eastern Colorado cities, farms and industries. Most of the water in Boulder Reservoir comes from the CBT and Windy Gap Projects through Carter Lake, although runoff from local drainage basins also adds to the water supply. Before the water in the Boulder Reservoir is used for municipal purposes, the water is treated at the Boulder Reservoir Water Treatment Plant.
