The WGFP includes construction of Chimney Hollow, a 90,000 acre-foot reservoir near Carter Lake in Larimer County. An acre foot serves approximately two single-family household equivalents. The reservoir will store water for multiple agencies, with about 30% of the volume being allotted for Broomfield’s use. The new reservoir will be adjacent to Carter Lake Reservoir as shown in the map. The proximity of Chimney Hollow to Carter Lake Reservoir and the Southern Water Supply Pipeline will allow the new reservoir to be easily integrated into existing infrastructure. The WGFP participants include Broomfield, Erie, Greeley, Lafayette, Longmont, Louisville, Loveland, Superior, Fort Lupton, Central Weld County Water District, Platte River Power Authority, Little Thompson Water District, Estes Park, and Evans.
