The lake is full and the surface area is approximately 1,500 acres at maximum elevation and the reservoir area includes a total of approximately 5,500 acres. The reservoir site is two miles from downtown Durango and is poised to provide a significant recreational amenity to the area. Lake Nighthorse is currently closed to the public.
