The following is a list of lakes in Ohio. According to the Ohio Department of Natural Resources, there are approximately 50,000 lakes and small ponds in the U.S. state of Ohio, with a total surface area of about 200,000 acres (81,000 ha). About 2,200 of these lakes are 5 acres (2.0 ha) or greater, with a total surface area of 134,000 acres (54,000 ha). These 2,200 include both public and private lakes. The United States Environmental Protection Agency estimated (from an electronic file generated from 1:100,000 scale maps) that Ohio has 5,130 lakes totaling 188,461 acres (76,267 ha). The difference in the number of lakes estimated by USEPA and ODNR is likely related to numerous small ponds (high number, small acreage) not detected on the 1:100,000 scale maps.
