Eucha, also known as Upper Spavinaw Lake, is a local government-owned water supply reservoir located in Delaware County, Oklahoma. Managed by the city of Spavinaw, this dam was completed in 1952 and serves as a crucial source of water for the surrounding area. With a capacity of 119,000 acre-feet and a normal storage of 79,600 acre-feet, Eucha plays a vital role in meeting the water needs of the community.

Situated on the Spavinaw Creek, Eucha has a dam height of 95 feet and a structural height of 95 feet. The reservoir covers a surface area of 2,860 acres and has a drainage area of 360 square miles. With a controlled spillway and a maximum discharge capacity of 298,000 cubic feet per second, the dam is designed to manage high hazard potential while maintaining fair condition assessment.
