Texas waters hold onto summer warmth as fall signals build
South Texas gauge readings still read like summer: the USGS site near the coastal river system logged 87°F this morning, with a companion gauge upstream at 85°F and flow holding low around 60 cfs. That's warm water for late September, and it lines up with what North Texas Catfish Guide has been reporting out of Eagle Mountain Lake near Fort Worth — hot water, minimal wind, and a subtle bite anglers describe as a "ghost bite," where fish barely touch the bait and hook-sets have to be dialed in to connect. The guide also notes plenty of small fish mixed in with better keepers, meaning some sorting is part of the game right now. Across the state, conditions read as a classic late-summer holdover rather than a hard fall shift just yet.

What's next
With water still sitting in the mid-to-upper 80s and flow running low, expect the pattern to hold steady over the next few days rather than flip quickly. Low, stable flow at the upstream gauge (60 cfs) points to calm, clear conditions rather than a runoff event, which typically favors early-morning and late-evening windows before the day heats the shallows further.
If air temperatures start easing as we move deeper into the first week of October, look for water temps to follow with a lag, and for the ghost-bite pattern North Texas Catfish Guide describes to firm up into more confident strikes as fish key onto shortening days. The Waning Gibbous moon this week favors low-light feeding periods, so dawn and dusk trips are worth prioritizing over the coming weekend.
Anglers heading to lakes with recent boat traffic should expect continued weekend pressure until temperatures break more decisively.
Context
Texas lakes and rivers typically hold summer-pattern warmth well into September, with a true fall cooldown and feeding shift usually arriving through October as nights lengthen. Water in the mid-to-upper 80s and low, stable flow are consistent with that seasonal lag rather than anything unusual for the date. The transition ahead is a normal one for the region: expect a gradual firming of bite windows around dawn and dusk before a more decisive pattern change later in fall. Check state regulations before harvesting, since seasonal rules can shift with the calendar.
