Safety

CautionThis route has hazards or access considerations that require extra verification.
TPWD says paddlers at South Llano River State Park must use the designated landing and portage around the damaged bridge area before reentering downstream.
Safety details
- Below the portage, expect shallow riffles and occasional snags, especially when the gauge is near the conservative floor.
- Heavy rain can raise this spring-fed river quickly enough to turn a casual half-day float into a fast current check.

Take-out
Flatrock Lane CrossingUse the marked state-park launch and the named Flatrock take-out rather than improvised bank stops.
Road shuttle
Use a short Junction-area shuttle between South Llano River State Park and Flatrock Lane Crossing. If you are entering the park only to launch, reserve day use first during the busy season.
Additional access notes

Use the South Llano gauge at Flat Rock Lane near Junction. Treat 65 cfs as the conservative floor and expect a cleaner ride above roughly 100 cfs. At low water, the biggest issue is scraping through riffles and weaving around woody edges.
