Formed by the completion of the Ozark-Jeta Taylor Lock and Dam and Powerhouse in 1969, Ozark Lake reaches 36 miles westward to the James W. Trimble Lock and Dam near Fort Smith, Arkansas. At normal navigation pool, Ozark Lake contains about 10,600 surface acres of water with 173 miles of shoreline. Formed by the completion of James W. Trimble Lock and Dam in 1969, John Paul Hammerschmidt Lake has approximately 120 miles of shoreline and 7,700 acres of surface water. Hammerschmidt Lake extends 26 miles west, about half in Arkansas and half in Oklahoma.

Ozark-Jeta Taylor Lock and Dam and James W.

The navigation system was authorized by the River and Harbor Act of 1946 and modified by subsequent acts of Congress.
