El Dorado Lake is a reservoir on the Walnut River, 0.5 miles (0.80 km) north-east of El Dorado, int the Flint Hills region of Kansas. The lake is part of El Dorado State Park.


El Dorado Lake is located in Butler County, Kansas, United States. The are many entrances into the lake area.

The lake consists of approximately 8,000 acres (32 km2) of water, 4,500 acres (18 km2) of park lands and 3,500 acres (14 km2) of wildlife area.


It was constructed by the U.S. Army Corps of Engineers and was completed in June 1981. During its construction, the present lake incorporated two smaller lakes that were already in existence, Bluestem Lake and old El Dorado Lake. The old El Dorado Lake was completely inundated by the new larger lake, but the dam of Bluestem Lake was breached and the remnants of that dam can still be seen on the Shady Creek arm of the lake. Management of the reservoir resources has been granted to the Kansas Department of Wildlife and Parks.

Zebra Mussels in El Dorado Lake[edit]

Zebra mussel veligers (larval zebra mussels) are too small to be seen with the unaided eye and they can be found in boat livewells, minnow buckets, boat bilges, water toys and anything else that is capable of holding even a small amount of water.
