The site of the proposed Wild Horse Reservoir has favorable topography, geology and environmental conditions. The depth and surface area of the reservoir would be optimized to help minimize evaporative loss.

The reservoir would be impounded by four dams for a surface area of approximately 1,650 acres and 93,000 acre-feet of active storage. Water would be transported into Wild Horse Reservoir from a new tap on the existing Otero Pipeline and through an inlet valve house. The proposed 60-inch-diameter inlet pipeline would be approximately three miles long. Water would move out of Wild Horse Reservoir from the outlet works valve house through approximately nine miles of new 66-inch-diameter outlet pipeline connecting to Spinney Mountain Reservoir inlet works.

Construction would occur seasonally over approximately five years, including reclamation. The target construction date is mid 2020s with completion in the early 2030s. At maximum construction of the reservoir, a workforce of up to approximately 500 people is anticipated. Temporary housing would be constructed on city-owned property.

Aurora Water and its contractors are committed to working closely with Park County, local residents, businesses and others to minimize and address impacts. Aurora and/or its contractors would coordinate directly with any impacted landowners before and during construction to answer questions.

As with any major infrastructure construction, various components of the Wild Horse Reservoir construction would require the movement of trucks and machinery through roadways in Park County. Portions of CR53 would be relocated, and some other roads may be closed for short periods, however, access to properties in the area will be maintained. Any traffic reroutes would always be clearly marked before and during road closures or construction. Construction areas would be appropriately marked with signs and fencing. Safety will be paramount on this project.
