Fall cool-down sets up Hill Country crappie and bass pattern
Hill Country water is still warm but the seasonal turn is underway, and the gauges show it. USGS gauge 08155500 reads 72°F with flow near 18 cfs, while gauge 08170990 reads 70°F with no measurable flow. Gauge 08105891 sits at 84°F, a reminder that shallow, slow water is still holding summer heat. Gauge 08158000 shows 173 cfs, a moderate run on the lower river. For technique, Wired 2 Fish notes that crappie go from finicky to aggressive almost overnight once the first cool front blows through, and that fall fishing is an entirely different approach from other seasons. Tactical Bassin points to jigs, soft jerkbaits and topwater around hard structure such as dock pilings, laydowns and rocks as the fall pattern.

Water in the low 70s is right where fall fish begin shifting toward baitfish and cover. Expect that movement to accelerate with each cold front, and the bite to improve as temperatures step down through the 60s.
Plan around the early and late hours. The New Moon means dark nights, and the first and last light windows are typically the most productive when fish are pushing bait shallow. Midday sun tends to slow things, so slow down and fish structure more thoroughly then.
If you are targeting crappie, look for fish stacking on deeper structure and brush, and work them methodically. For bass, Tactical Bassin suggests shallow jigs and soft jerkbaits near docks and wood, with finesse presentations on tougher days. Check conditions before you go, since flows can change quickly after rain.
Context
Mid-October is typically the transition from the late-summer slowdown into the productive fall season on Central Texas reservoirs. Warm water that held fish deep through August and September gives way to cooler nights, and fish begin following baitfish into the shallows. The warm 84°F reading at one gauge shows the cooling is not uniform yet, so conditions vary from one stretch of water to the next. Expect the pattern to keep improving into November.
