 * Aurora is in many reservoirs across Colorado. Since we move our water to meet many needs, this number represents Aurora’s water in these other reservoirs at this time. All numbers in this report should be considered to be an estimate or projection. Included in shared storage is Aurora's share in Homestake Reservoir, Turquoise Lake, Twin Lakes Reservoir, Pueblo Reservoir, Strontia Springs Reservoir and Lakes Meredith and Henry
In addition to the existing reservoirs above, Aurora Water is proposing to build a new off-channel reservoir — the Wild Horse Reservoir Project — west of Spinney Mountain Reservoir near Hartsel, Colorado, in Park County. This project is currently in the planning and permitting phase. Sign up for Wild Horse Reservoir Project updates.
