摘要

Lake Ogallala in western Nebraska began as a borrow pit for the construction of Kingsley Dam but today has a reputation as an excellent cold-water fishery. The Central Nebraska Public Power and Irrigation District built Kingsley Dam between 1936 and 1941 to form Lake McConaughy, the storage reservoir for the district's irrigation and 51.9-MW Kingsley hydroelectric project. During construction of the dam on the North Platte River, huge electric dredges - one on each side of the dam's centerline - pumped sand and gravel from the riverbed to form the upstream and downstream embankments around a watertight clay core. The two dredges removed more than 19.8 million cubic meters of sand and gravel from the riverbed in building the 5.6-kilometer-long dam. Lake Ogallala was formed by the dredging activity on the downstream side of Kingsley Dam.
