The Colorado River is a big part of life and history in Bastrop County, Texas. It’s more than just a body of water—it’s a natural landmark that’s shaped the landscape, supported communities, and drawn people to its banks for centuries.
At 862 miles long, the Colorado River is the longest river that begins and ends entirely within the state of Texas. In Bastrop County, it flows from the northwest to the southeast, cutting right through the middle of the county and passing directly through the towns of Bastrop and Smithville. If you look at a map, it’s easy to spot—like a winding ribbon running diagonally across the land.
What makes the Colorado River especially fascinating is how it’s carved the land over time. Starting way up on the Llano Estacado, near the New Mexico border, this first-order stream flows all the way to the Gulf of Mexico. Over thousands of years, it has cut deep into the earth, leaving behind layers of river terraces—from ancient Ice Age gravel beds to modern sandbars. These terraces show the story of a river that has mostly kept a gentle, meandering shape for ages, shaping the lowlands of Bastrop County as it went.
Many creeks and springs across the county eventually flow into the Colorado River, making it the main artery of Bastrop’s natural water system. Historically, this river has always been important. Spanish explorers once used it as a crossing point along El Camino Real, the royal road through Texas. That crossing eventually became the town of Bastrop. Later, 19th-century ferries launched from the same spot.
Today, you can still get out on the river in just about the same way—though now it’s more about recreation than transport. Public access points like Wilbarger Landing, Fisherman’s Park, and the Bastrop County Nature Park make it easy to canoe or kayak. Heading upriver from Bastrop takes you into lush forests, while heading downriver gives you a view of the Lost Pines along Red Bluff, and eventually into open prairie. Fishing is popular, too—you might catch catfish, carp, or panfish.
Down in Smithville, you’ll find even more access points—at the Highway 95 bridge and at Riverbend Park. Trips from there reveal even more scenic variety: forested bluffs, open plains, and even fossil beds where bones and teeth from ancient creatures like mammoths and mastodons have been found near gravel quarries. It’s a mix of natural beauty and prehistoric mystery—all accessible by boat in a day’s outing.
The Colorado River has also had its wild side. It used to flood with little warning, especially in the early 1900s. Those destructive floods helped prompt the creation of the Highland Lakes system—dams and reservoirs upriver designed to help control the flow. There are no dams in Bastrop County itself, so the river here still runs freely. Today, it’s a valuable resource for irrigation, city water, and outdoor recreation.
In short, the Colorado River in Bastrop County isn’t just a waterway—it’s a piece of Texas history, a source of life, a place for adventure, and a storyteller of ancient times. Whether you’re paddling through tree-lined banks, casting a fishing line, or just enjoying the view, you’re part of a long tradition of life along this iconic river.
