Lake Yahola, Reservoir in Tulsa, Oklahoma, United States

Lake Yahola is a city-owned, concrete-lined reservoir of 437 acres in Mohawk Park, Tulsa, with an average depth of 18.5 feet and 3.2 miles of shoreline. It holds 2 billion US gallons of raw water piped from Lake Spavinaw and sits next to the Mohawk Water Treatment Plant.

Lake Yahola was completed in 1924 as a city-owned, concrete-lined reservoir holding 2 billion US gallons, fed by pipeline from Lake Spavinaw. The original Mohawk Water Treatment Plant, built to process 90 million gallons per day, went into service in 1929; a new plant rated at 100 MGD replaced it in 1998 and has since been expanded to 200 MGD.

The name Yahola comes from the Muscogee (Creek) language, and the reservoir sits inside Mohawk Park, a Tulsa city park. Fishing from the shoreline is permitted, but the docks are closed to the public and boating is not allowed. Birdwatchers head to the adjacent Oxley Nature Center.
