Lake Eucha Park State Park

Lake Eucha Park is a 31-acre (13 ha) former Oklahoma state park located in Delaware County, Oklahoma. It is now owned and managed by the city of Tulsa, and the closest town is Jay, Oklahoma. The park was previously known as Lake Eucha State Park and Upper Spavinaw State Park. There have been parks, state and otherwise, around the lake since at least 1938; the oldest lease clearly applying to this park was started in 1967.
