The Trinity is one of the most significant alligator gar rivers in North America. Fish over 100 lbs exist here. But harvest is tightly regulated — this page covers everything you need to know before you target them.
Alligator gar are one of the most regulated freshwater species in Texas. Violations can result in significant fines. Before you fish for them, read this page carefully and verify current rules at TPWD. Key points:
Alligator gar are a prehistoric species — they've existed largely unchanged for over 100 million years — and the Trinity River is one of their strongholds in Texas. The river's warm water, abundant forage, and undisturbed backwaters provide ideal habitat. Fish that have spent decades in this system grow to genuinely massive sizes; 6-foot, 100+ lb fish are a realistic possibility on this stretch.
For anglers, the Trinity offers one of the few places in the country where you can legitimately target alligator gar from a boat or the bank with standard tackle. It's a specialty fishery — not beginner fishing — but it's accessible if you understand the rules, the habitat, and the biology.
1 alligator gar per angler per day. This applies everywhere in Texas, regardless of method.
Any harvested alligator gar must be reported to TPWD within 24 hours. This is a statewide requirement. Failure to report is a violation even if your bag limit was legal. Report online at TPWD's mandatory harvest reporting page.
On the Trinity River corridor, only alligator gar under 48 inches in total length may be retained. Large fish — precisely the trophy specimens most anglers want — must be released. This is a conservation measure to protect the breeding population. Know this rule before you keep any fish.
Special restrictions apply to taking alligator gar by archery methods on the Trinity corridor. If you plan to bowfish, verify current archery-specific rules at TPWD before fishing.
Always verify current rules at TPWD Bag & Length Limits and Trinity River Special Regs. Rules can and do change between seasons.
Alligator gar are warm-water fish. Late spring through summer — May through September — is the primary season near Midway. Stable, warm water is the trigger. Cold water in winter pushes them into the deepest holes where they become sluggish and nearly inactive.
Alligator gar have a hard, bony mouth — hooks don't penetrate easily. The standard approach is to use a treble hook snell or a rope lure (a frayed nylon rope ball the gar's teeth tangle in) and let the fish run with the bait before setting hard multiple times.
The current consumption advisory specifically states that no species of gar should be consumed from the Trinity River in the area affected by the Lake Livingston advisory (US 287 to US 90). This is not a caution — it is a do-not-eat advisory. Practice catch-and-release for gar unless you are retaining one legal-sized fish and are aware of the advisory implications.
