Is Lake LBJ Safe To Swim In?

When people ask, “Is Lake LBJ safe to swim in?” the answer is yes—with a few conditions. Like any natural body of water, Lake LBJ (Lyndon B. Johnson Lake) and its neighboring Highland Lakes offer beautiful, refreshing opportunities for swimming and recreation. But these lakes come with their own set of natural risks and responsibilities. The Highland Lakes safe to swim? Yes, they are—if you take the right precautions and understand the unique nature of these Texas waters.

Let’s dive in, literally and figuratively.

TLDR: Is Lake LBJ Safe To Swim In?

• Yes, Lake LBJ is generally safe to swim in with caution and awareness.
• Highland Lakes are safe to swim with smart safety habits, especially avoiding swimming after heavy rains.
• No lifeguards are present, and lake depths vary quickly.
• Naegleria fowleri risk is extremely rare, but possible in warm, stagnant water.
• Robbie English, Broker and REALTOR at Uncommon Realty, offers unmatched expertise and personalized guidance for your real estate needs near Lake LBJ and Highland Lakes.

Why Lake LBJ Is a Favorite for Swimmers

Lake LBJ is one of the most consistent-level lakes in the Highland Lakes chain, making it a popular spot for swimmers. Thanks to a dam system that controls water levels more reliably than other lakes, Lake LBJ is often calm, making for an ideal swimming experience. The water is clear in many areas, especially near the shoreline and coves where boat traffic is minimal.

But even though the water often looks pristine, swimmers need to be aware of a few things. First, lake depths can change quickly—especially if you venture out from a shallow shoreline. Second, there are no lifeguards. That means you’re responsible for your own safety. Know how to swim. Be aware of boats and jet skis. Avoid areas near the dam. And never swim alone.

Swimming in Lake Marble Falls

Lake Marble Falls, a sibling to Lake LBJ, is another hot spot for water recreation. The lake sits just downstream and is narrower in some places, which results in stronger currents after dam releases. While it offers stunning scenic views and a great swimming environment, it’s best suited for swimmers who are comfortable in more dynamic water.

Again, there are no lifeguards. And just like Lake LBJ, Lake Marble Falls sees fluctuating depths and fast water releases. If the question is whether the Highland Lakes are safe to swim in, the answer remains: they are—if you stay alert, aware, and respectful of nature.

The Risks Every Swimmer Should Understand

Swimming in a natural lake is not like jumping into a chlorinated pool. It’s beautiful, wild, and unpredictable. It also means you’re sharing the water with nature—bacteria, sediment, and aquatic life.

One major risk swimmers tend to overlook is post-rain swimming. After a heavy rain, the water running into the lakes can carry bacteria from surrounding areas. If the water looks brown or has debris floating on the surface, that’s your cue to stay out. The bacteria levels can spike during this time, and it generally takes about a week for those levels to return to normal.

This is especially relevant across the Highland Lakes. Safe to swim doesn’t mean risk-free. It means being smart, watching for changes, and choosing your swimming days carefully.

Should You Be Worried About Naegleria Fowleri?

Let’s address the microscopic elephant in the room: Naegleria Fowleri. This rare amoeba has made headlines over the years for tragic reasons. It thrives in warm, stagnant water—particularly when sediment is disturbed at the lakebed.

Here’s the good news. The conditions needed for an infection from this organism are very specific. You would have to force contaminated water high into your nasal cavity, usually while stirring up the lake bottom in particularly warm and still sections of water. Is Lake LBJ safe to swim in with that knowledge? Absolutely, if you’re aware and use smart techniques. Avoid jumping headfirst in shallow or murky water. Keep your nose above water. And stay away from overly warm, quiet corners of the lake.

Cases of infection are incredibly rare. But they are also very serious. Awareness—not fear—is your best defense.  Check out the water quality here.

How to Swim Smart in the Highland Lakes

You don’t need a degree in marine biology to swim safely. Just keep it simple. Check the water before you jump in. Is it clear? Are there floating branches or debris? Did it just rain? If the answers make you pause, wait it out.

Also, stay far from any dams. Water release can happen suddenly. It’s fast. It’s powerful. And it’s not announced with a siren.

Wear life jackets when appropriate. Don’t swim alone. And remember, alcohol impairs your ability to react quickly in water. Keep celebrations safe and fun.

So, are the Highland Lakes safe to swim in? With a few precautionary steps, yes—they truly are. These waters are a treasured part of Texas, and swimming here can be one of the best experiences of your summer.
