Hill Country lakes settle into a fall pattern for bass and cats
Water in the Austin area is holding steady and warm for mid-October. USGS gauge 08155500 reads 72°F with 24.8 cfs, gauge 08170990 shows 70°F with no measurable flow, and gauge 08105891 reads 83°F. That spread points to a clear split between cooler spring-fed or tailwater stretches and shallow, sun-heated water. Per Tactical Bassin, October bass fishing rewards a shallow approach with jigs, soft jerkbaits and topwater, fishing the subtle spots fish tend to use. Field & Stream adds that fall turnover rarely hits a whole fishery at once, so clean, clear water is the most direct route to bass. Smallmouth Bass is the only listed bass species we can name from the intel, so treat that tip as general fall guidance.

Expect the cooler readings to keep drawing fish toward comfortable temperatures over the next few days, with the warmest water (83°F) the least appealing. If nights keep cooling, shallow flats and creek arms should fire up first, and those are the places Field & Stream suggests checking for clear water ahead of turnover. Search baits such as spinnerbaits help locate active fish before slowing down.
Gauge 08158000 shows 268 cfs, which means current is moving on that stretch. Fish tend to hold on softer edges in moving water, so concentrate on seams and slack pockets rather than the main push.
For timing, plan around low light. Early mornings and the last hour before dark typically give the best topwater and reaction-bite windows in fall. With a waxing crescent moon, nights stay fairly dark, so daylight hours matter more than moon-driven feeding. Check state regs before harvesting anything.
Context
Mid-October in the Texas Hill Country usually marks the shift from summer heat to cooler fall patterns. Surface temperatures in the 70s are on schedule for the season. Fish that spent late summer deep or tight to cover typically move shallower as baitfish follow cooling water, and the fall bite often improves for several weeks. Reservoirs can start to show early turnover signs in the shallowest arms first, while the main lake stays stable.
