Warning Alert
Safety Closures in Effect at Rock Island State Park
The following alert is important for all Rock Island State Park visitors
TVA Great Falls Dam and/or the TVA Great Falls Powerhouse may release water on an irregular schedule. 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.

Access May Be Prohibited
Water levels are highly variable in the gorge due to releases of water from Great Falls Dam.
Active Water Release
When the Great Falls Dam is actively releasing water, it is unsafe to enter the gorge and all access will be restricted. During large releases from the dam, the entire gorge can quickly become flooded with water making conditions extremely hazardous.
These images show examples of how the water may look when access is prohibited versus when it is allowed.
How To Know
Water may be released suddenly from TVA Great Falls Dam or the TVA Great Falls Power House. The dam and power house are at two different locations about half a mile apart. The power house typically releases water at some point every day at irregular times. Swimming or wading downstream of the power house is not permitted at any time.
Guidelines to Follow
Where Can I Swim?
Swimming and wading are popular activities at Rock Island.
If the gorge is closed, head down to the swim beach! The swim beach is the most accessible area for swimming within the park and is ideal for visitors with children. This natural sand-silt shoreline of the Caney Fork River offers a boat ramp, reservable picnic pavilion, and restrooms. No lifeguards on duty.
Where Can I Hike?
There are lots of hiking trails located outside of the gorge area that visitors can enjoy if the gorge is closed. These areas include points of interest like Twin Falls and the Blue Hole.
