Hill Country lakes warm and settled for fall bass
Water temperatures across the Hill Country gauges are still comfortable for active fish. USGS gauge 08155500 reads 72°F with flow near 19.5 cfs, gauge 08170990 shows 70°F, and gauge 08105891 sits at 79°F. That spread suggests shallower, slower water is holding more heat than the stretches fed by cooler flow. Per Texas Fish & Game Magazine, October is a prime window for largemouth bass in Texas. Cooling water pushes baitfish into creeks and coves, and bass follow, often becoming more aggressive as they go.

If nights keep cooling, expect the 79°F water to drift down toward the low 70s. Bass should follow shad deeper into creek arms and pockets, which tends to concentrate fish and make them easier to find.
For technique, Tactical Bassin points to fall baitfish chases. Adding a blade to a swimbait, such as an underspin, brings extra flash and vibration when bass are working bait. A jerkbait is another fall staple, and the same outlet covers retrieves and colors for changing water conditions.
Plan around low light. Early morning and the last hour of daylight are typically the best windows when fish push shallow after bait. Midday, slow down and fish the edges of the warmer water, where fish may stage. With a waxing gibbous moon, the evening bite can run later into the night than usual.
Gauge 08158000 shows 834 cfs, so any moving water downstream carries noticeably more current. Plan accordingly if you fish near inflows or run a boat in those reaches. Check state regs before harvesting.
Context
Late October is typically the second feeding season for Texas bass. Reservoirs have shed their summer stratification, shad migrate into creeks, and fish feed heavily ahead of winter. Warm days with cooling nights keep this pattern strong. Against that backdrop, 70 to 79°F readings look about on schedule, with the warmest water lagging in the shallower, slower sections. Expect bass to settle into a clearer fall pattern as temperatures continue to fall.
