The Making of Lake McConaughy

Lake McConaughy was created by the construction of Kingsley Dam, a concrete gravity dam located on the North Platte River. It was built between 1938 and 1941 as part of the New Deal, a series of programs and initiatives launched by President Franklin D. Roosevelt during the 1930s in response to the Great Depression. The goal of the New Deal was to get Americans back on their feet. The dam serves several purposes, including flood control, irrigation, recreation, and hydroelectric power generation. The lake is named for Charles McConaughy, a local grain merchant who envisioned using the annual spring flooding of the North Platte River as a means of crop irrigation. In his effort to manifest his vision, McConaughy formed the Tri-County Supplemental Water Association in 1913. George Kingsley, a prominent farmer was named vice president of the organization. And the rest, as they say, is history.

The depth of  Lake McConaughy fluctuates throughout the year, depending on the needs of the dam and the flow of the North Platte River. During the summer months, the lake is typically at its lowest point, while during the spring and early summer, the lake may be higher due to increased runoff from snowmelt and rainfall. The Central Nebraska Public Power and Irrigation District in partnership with Nebraska Game and Parks Commission and U.S. Fish and Wildlife Service carefully manage the depth of the lake to ensure that it is safe for recreational activities and to ensure that it meets the needs of the dam. While the lake’s depth can change throughout the year, the partnership strives to maintain the lake at a consistent depth, within the safe operating range for the dam.
