El Dorado Lake is a reservoir on the Walnut River 0.5 miles (0.80 km) northeast of El Dorado in the Flint Hills region of Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, and water supply. El Dorado State Park is located on its shore.
The Flood Control Act of 1965 authorized construction of El Dorado Lake. The U.S. Army Corps of Engineers held groundbreaking ceremonies in September 1973, and construction began the following month. The reservoir became fully operational for flood control June 29, 1981.
Construction of El Dorado Lake incorporated two pre-existing smaller reservoirs: Bluestem Lake and the original El Dorado Lake. The original El Dorado Lake was built on Satchel Creek in 1927 as a water supply for the community of El Dorado. Bluestem Lake was built on Bemis Creek in the 1950s. The dams of both reservoirs were breached during the building of the larger El Dorado Lake and their waters subsequently inundated. The remnants of Bluestem Lake's dam are still visible in the Shady Creek arm of the present-day reservoir.
El Dorado Lake is located at 37°50′50″N 96°49′23″W / 37.84722°N 96.82306°W (37.8472402, -96.8230838) at an elevation of 1,335 feet (407 m). It lies in the Flint Hills in south-central Kansas. The entirety of the reservoir lies within Butler County.
