The top five rivers in Texas that are home to a large number of alligators are listed below.

One of the Texas rivers with the highest concentration of alligators is the Guadalupe River. This spring-fed river flows from Canyon Lake Dam toward the seashore for around 230 km. Locals refer to it as the “River of Dreams,” and rafting, fly-fishing, kayaking, and canoeing are all popular activities there. Numerous accounts of alligator sightings have been documented because of the regular visitors. First, on the upper Guadalupe River in May 2016, a kayaker saw a three-foot alligator. Five alligators have been caught and taken out of this region over the years, with the largest one being over eight feet long! Additionally, locals along the Guadalupe River have taken numerous pictures of alligators.

2. Trinity River

The Trinity River spans more than 710 miles and is situated in eastern Texas. Interestingly, its watershed is fully within the state, making it the longest river in the state. Because of this, it serves as the ideal source of water for more than 40% of the state’s population. The East Fork, West Fork, Elm Fork, and Clear Fork are its four principal branches. The Trinity River is thirty feet deep on average, though regular flooding has impacted this amount in some places.

Additionally, a variety of fauna finds the ideal habitat in this extensive ecosystem. This region is home to several alligators in addition to chinook salmon and steelhead trout. A consistent population of American alligators has been observed by Sam Kieschnick, an urban wildlife photographer for Texas Parks and Wildlife, who reports that the alligators frequently cross the Trinity River to reach Eagle Mountain Lake.

3. Brazos River

The 840 miles of the Brazos River traverse central and eastern Texas. This area is home to American alligators, which are frequently sighted in and near Brazos Bend State Park. An estimated 250 adult alligators live in the 1,000 acres of water that make up this river!

4. Nueces River

It empties 16,950 square miles of water into the Gulf of Mexico and is roughly 315 miles long. Moreover, the drainage from this river is around 620,000 acre-feet annually! The name Nueces River, which translates to “River of Nuts,” was given by early Spanish colonists who observed how many pecan trees were growing along its banks. This river is home to a large population of American alligators in addition to nuts. These frightening animals are rarely reported, yet they have been seen several times cruising this river. As a result, it was ranked as the second most alligator-infested river in Texas.

5. Rio Grande River

The Rio Grande River spans 1,896 miles and varies greatly in depth from as shallow as 6 feet to as high as 60 feet. Ghost-faced bats, green kingfisher birds, and Texas pocket gophers are a few of the most prevalent species in and near the river. There are also thousands of American alligators living in the Rio Grande. Although the precise number of gators that live in this river is unknown due to environmental conditions like drought, sightings have been reported as recently as May. Additionally, Laguna Atascosa National Wildlife Refuge, which is east of Rio Hondo, is home to a known population. It is true that the population of alligators declines as one moves farther inland from the ocean.
