It is operated primarily for flood control and municipal water storage in conjunction with downstream Sweetwater Dam but the reservoir is also open to the public for fishing.The dam stands 203 feet (62 m) high and spans 765 feet (233 m) across the narrow gorge of the Sweetwater River, 2.4 miles (3.9 km) south of Alpine. It is built entirely of concrete and has a thin arch design. Loveland is the younger of the two dams on the Sweetwater River; the other, Sweetwater, was built in 1888 while Loveland was only constructed in 1945. It is named after Chester H. Loveland, president of the California Water and Telephone Corporation, the firm that built it.
