Fall transition sets up dawn bite windows on Travis, LBJ, Buchanan

What's next

Look for the low-light windows to matter more over the next few days: the full moon keeps nights brighter, which tends to push some feeding activity later into the evening and earlier into the morning. If the seasonal cool-down continues, baitfish typically push toward secondary points and creek arms on Highland Lakes reservoirs, concentrating predator activity in the same water.

Plan around the first two hours of daylight and the last hour before dark this weekend, following Wired 2 Fish's read on prioritizing those windows through the transition.

Context

Late September is early in the fall turnover cycle for the Highland Lakes chain, a period that typically runs into November as surface water cools and mixes with deeper layers. Travis, LBJ and Buchanan tend to follow a similar rhythm to nearby Hill Country reservoirs, where shorter days and cooling water push baitfish and predators into more predictable low-light patterns before the fuller turnover arrives. This stretch of the calendar is generally considered a build-up phase rather than peak fall fishing, with the most consistent bite typically arriving as nights continue to cool through October.
