What’s the Deepest Lake in Texas?

Talk to any Texan long enough, and you’ll eventually hear how everything is bigger in Texas. However, that’s not always the case when it comes to their lakes. Lake Michigan is the largest, and Crater Lake is the deepest. So while it’s not likely to steal those awards, you might impress any Texan if you spout out your knowledge of the deepest lake in the Lone Star state.

Today, we’ll introduce you to Lake Buchanan and why it’s worth visiting the next time you’re there. Let’s dive in!

How Many Lakes Are There in Texas?

The state of Texas is home to more than 7,000 lakes. While this may sound like an impressive number, the Lone Star State sits at number eight among the states with the most lakes. States like Florida, Michigan, and Minnesota have thousands of more lakes than Texas.

However, the immense state of Alaska has more than three million unnamed natural lakes, plus a few thousand named lakes.

What’s the Deepest Lake in Texas?

There’s no lake deeper in all of Texas than Lake Buchanan. It sits near the center of the state and has a maximum depth of approximately 132 feet. It’s a popular lake for various recreational purposes, including swimming, fishing, paddle boating, and kayaking. You’ll likely see a jet ski or two zipping around the waters too.

About Lake Buchanan

There are a few things you need to know to make the most of your time on Lake Buchanan. First, it was created in 1938 with the completion of the Hamilton Dam and Reservoir, which later changed to Lake Buchanan. Second, Old Bluffton is a flooded town that sits at the bottom of the lake. During extreme droughts, there’s a chance you can catch a glimpse of it. 

Let’s look at other important facts and information that will help you have a great time when you visit.


Lake Buchanan sits approximately 55 miles northwest of Austin, Texas. Llano and Burnet are the only towns near the lake. However, the tiny Tow, Texas community sits along the lake’s northwest side. If you find yourself traveling across the state on State Road 29, you’ll drive right by the lake and can even see  Buchanan Dam off in the distance.


The lake is 22,333 acres and has 124 miles of shoreline. While Lake Buchanan takes the crown for being the deepest lake in the state, it sits in 17th place on the list of the largest lakes in the state. If you want to visit some of the largest lakes in the state, you’ll need to visit Toledo Bend Reservoir (182,490 acres) and Sam Rayburn Reservoir (112,590 acres).


The lake is a popular spot for various recreational purposes, including swimming, fishing, paddle boating, and kayaking. You’ll likely see a jet ski or two zipping around the waters too. Bring a book and soak up the sun at one of the beaches surrounding the lake. It’s a great place to cool off during the sweltering summer days that Central Texas experiences.

Can You Swim in Lake Buchanan?

Swimming is a popular activity on Lake Buchanan. As we mentioned earlier, the summer heat in Central Texas can be intense, and hitting triple digits is not uncommon. Some of the best places for swimming are Beaver Creek, Morgan Creek, Lake Buchanan Waterfall, and several other locations along the lake’s western shore.

Are There Alligators in Lake Buchanan?

Like many bodies of water in this part of the state, there are alligators in Lake Buchanan. However, there isn’t an increased population of alligators. These alligators rarely have negative interactions and encounters with humans.

Swimming, boating, and other aquatic activities are relatively safe in Lake Buchanan. You’re most likely to catch a glimpse of an alligator bathing on the beach. You and the alligator can go about your days peacefully if you keep your distance.

Is Lake Buchanan Good for Fishing?

Many Texas lakes are a paradise for anglers, and Lake Buchanan doesn’t disappoint. The lake has some great spots for striped and white bass. However, blue catfish, largemouth bass, and channel catfish are also commonly caught in the lake. If you’re inexperienced with fishing in Texas, there’s no shortage of local charter services willing to help set you up for success.
