Access caveats and watch for
Access caveats
- TPWD says the damaged state-park bridge apron is closed and that paddlers must exit at the designated location, portage around the bridge, and reenter downstream.
- Use the marked state-park launch and the named Flatrock take-out rather than improvised bank stops.
- Private shoreline begins quickly outside the park corridor, so keep rests brief and at the named public access points.
Watch for
- The required bridge portage at South Llano River State Park.
- Low-water scraping and minor route reading through shallow riffles when the gauge is near the conservative floor.
- Strainers, changing current after rain, and slippery rocks at either access.
