Around Fort Collins, the big reservoirs hold project water from the other side of the mountains

The two large reservoirs west of Fort Collins and Loveland — Horsetooth and Carter Lake — are not just scenery and boat ramps. They are storage for a big water-moving system, and that matters when you try to understand where local water comes from.

Much of the water they hold did not fall on the Front Range. It started on the western side of the Continental Divide and was carried east through the Colorado-Big Thompson Project, a federal transmountain system built last century. The water is stored in these reservoirs and then shared out to cities, farms, and other users on the east side.

Why a buyer or new resident should care: this project water moves in its own allotments, managed by federal and regional agencies, and it is separate from a private well or a city tap. Having a reservoir nearby does not mean a property has rights to that water. The household supply still has to be checked on its own — whether it is a city connection, a district, or a permitted well.

To learn how the system is owned and operated, start with the Bureau of Reclamation and the regional water district, and confirm any household supply with the state water agency.
