Rock Island State Park

Water discharge may change day to day or even hour to hour. All river gorge areas downstream of the TVA Dam are closed when the dam is in Active water spill mode or a discharge is likely for the day. Before planning your visit, please check TVA's website for Great Falls Dam and Powerhouse for the most current water discharge schedule. Visitors are encouraged to check the discharge schedule often. Discharge schedules can change rapidly based on lake levels, rainfall forecasts, etc. Water releases may occur with or without warning any time you are near a TVA dam or powerhouse. Visitors should be prepared for a quick exit should they hear warning sirens or notice water rising. Life jackets and hiking shoes are strongly encouraged in this area. The park has also seen very high visitation over the last year. Please do not park on roadsides or in non-designated areas. If the park is full, please consider visiting another state park in the area. Please check the park’s Facebook page for updates before your visit.

Know Before You Go
The park often experiences high visitation. Please do not park on roadsides or in non-designated areas. If the park is full, please consider visiting another state park in the area. Also, please check the status of the Caney Fork River Gorge section of the park before visiting, as access is dependent on approval from TVA based on hourly water release predictions. Gorge closures may occur without notice and can be in place for varying lengths of time. Learn more on our safety information page.
