About Blanco River

A spring-fed Hill Country gem flowing through Wimberley and San Marcos. TPWD has prioritized the Blanco for Guadalupe bass genetic restoration — pure-strain fish are stocked to reduce smallmouth hybridization. Gin-clear water over white limestone enables exceptional sight-fishing. A dedicated fly fishing community has developed around the Blanco's carp population — double-digit fish on the flats offer technical, saltwater-style stalking. John Knox Ranch provides free public access.

Regulations

Texas Freshwater Fishing License required. Statewide black bass regs: 14" minimum, 5-fish bag. No special regulations on Blanco main stem. Catch-and-release of Guadalupe bass is strongly encouraged given the ongoing genetic restoration program.
