Cooper Lake Boat Ramp at the Tira unit provides public access to Jim Chapman Lake (also known as Cooper Lake) on the South Sulphur River in Hopkins County.

The ramp is managed by Texas Parks and Wildlife Department and is one of several multi-lane boat ramps available at Cooper Lake State Park, making it a reliable access point for boating and water recreation.

Day-use fees are $5 per person (13+), and no fishing license is required when fishing from shore or designated piers at the park.
