The following is a list of lakes in Oklahoma located entirely (or partially, as in the case of Lake Texoma) in the state. Swimming, fishing, and/or boating are permitted in some of these lakes, but not all.
Oklahoma has more than 200 lakes created by dams. All lakes listed are man-made. Oklahoma's only natural lakes are oxbow and playa lakes. Oklahoma has sixty-two oxbow lakes at least 10 acres in size. The largest, near the Red River in McCurtain County, is 272 acres.
Playa lakes are found in saucer-shaped depressions in the high plains region. They are usually intermittent, holding water only after rains. Oklahoma has about 600 playa lakes.
Ranked by surface acres, Lake Eufaula is the 34th largest lake in the United States and Lake Texoma is the 38th largest.
