Ensuring a Reliable Water Supply for Aurora
The Wild Horse Reservoir Project is a proposal by Aurora Water to build a new off-channel reservoir west of Spinney Mountain Reservoir near Hartsel, Colorado, in Park County. The proposed project would provide the critical water storage that Aurora Water needs to ensure reliable water supply for community needs and maintain emergency water reserves during severe droughts or system emergencies.
Currently, several sites in Park County are being evaluated, and a final location will be determined through the federal environmental review process.
Aurora Water maintains the project information on this website. The Bureau of Land Management (BLM), as the lead federal agency, is managing the federal National Environmental Policy Act (NEPA) process and will prepare an Environmental Impact Statement (EIS), which is a public-facing, comprehensive analysis of the potential environmental and social impacts from the Wild Horse Reservoir Project. The NEPA process is expected to formally begin in 2026 and take about two years to complete. More information will be posted as it becomes available.
