Rio Grande Fishing Report: Reds, Drum, and More in the Lower Valley
Published 7 months ago
Description
Artificial Lure here with your Rio Grande, Texas area fishing report for September 27th, 2025.
Sunrise had us on the water by 7:23 AM, with sunset coming at 7:29 PM—a good 12 hours to get after ‘em. Locals woke up to a gentle southeast breeze, temps hovering in the low 70s at dawn and climbing toward the mid 80s by afternoon. Light clouds this morning, hoping to burn off by noon, and that means both shade lines and structure are top priorities. According to SaltwaterRecon’s regional forecast, the tides will be outgoing until about noon and then swinging back in—plan your flats fishing around that push for the best shot at redfish and drum.
Now, onto the fish. This past week, much of the action has centered around the lower Rio Grande, backwater cuts, and oxbow lakes. Recent trips, as reported by Captain Experiences, have seen solid numbers of redfish caught up shallow—plenty of slot reds, with a few needing a tag. Big drum have been spotted tailing alongside them, especially around Laguna Atascosa flats. Don’t overlook the hybrid striped bass and channel catfish around the deeper river bends; cut bait and live shad have accounted for some nice fish in the last 48 hours.
On the freshwater side, Texas Parks & Wildlife records from 2024-25 reflect catches of Rio Grande cichlid, Guadalupe bass, and blue catfish. The cichlid bite continues to be reliable on worms and crawfish imitations in the lush weed pockets. Largemouth bass up to 7 pounds have been coming on black goober bugs and foam spiders early, shifting to soft plastics and spinnerbaits as the sun climbs.
Your best bets today:
- For **redfish** and **black drum**: Dead shrimp or live mullet under a popping cork. If you’re throwing artificials, a chartreuse paddle-tail or gold spoon is hard to beat during that moving water window late morning.
- For **largemouth bass** and **Guadalupe bass**: Early is topwater time—try buzzbaits, poppers, or a classic black foam spider. As light angles steepen, slow-roll a watermelon Senko or swap to a Texas-rigged lizard.
- For **channel and blue catfish**: Cut bait, chicken liver, or even bluegill chunks are working around brush piles and dropoffs. Nightcrawlers have picked up both big cats and freshwater drum.
- For the **Rio Grande cichlid**: Bits of worm, small jigs, or a Briminator fly pattern will fill your stringer in the slackwater and edges.
As for hotspots:
- Boca Chica flats, especially the southern edges near the mouth, have been producing reds and drum on that incoming tide.
- The Falcon Dam tailrace is a catfish magnet after a rain, so with the week’s cooler weather you can expect bite windows to open up as temps stabilize.
- Don’t skip the Arroyo Colorado cutoff; hybrid stripers and panfish are biting around submerged brush and inlets.
Top lures and baits this week, pulled from both recent catches and historic TPWD records: Mepps Aglias for bluegill and hybrids, Prince Nymphs and crawfish Briminator flies for cichlid and panfish, gold spoons and DOA shrimp for inshore saltwater. Natural baits like live mullet or dead shrimp remain the sure bet for slot reds and drum.
Conditions are ripe for a solid bite all day. Watch for that mid-morning tide swing: once water floods back into the marsh, predators will be shadowing mullet schools. Keep extra leader handy—those redfish have been pushing the 28-inch mark this week.
