Calamus Dam, located on the Calamus River, was completed by the U.S. Bureau of Reclamation in May, 1986. The dam is a zoned, rolled-earth filled structure 96 feet high with a crest length of 7,295 feet. It was built to provide storage for off-season water flows for release during the irrigation season. A facility of the North Loup Division of the Nebraska-Kansas project, the dam creates a reservoir with 31 miles of shoreline, 127,400 acre feet of storage and a surface area of 5,123 acres. Irrigation releases and operation of the dam are the responsibility of the Twin Loups Reclamation and Irrigation District. Approximately 53,000 acres of Nebraska farmland will be served by this reservoir.
