Think Twice Before You Cannonball Into Lady Bird Lake
TL;DR: Austin has banned swimming in Lady Bird Lake since 1964 - and the core hazards (unpredictable currents, underwater debris, low visibility, and sporadic toxic algae) haven’t gone away. The latest staff recommendation to City Council is to keep the ban. Enjoy the lake by paddleboard, kayak, or at sunset - and save your swims for Barton Springs, Lake Austin, or Lake Walter E. Long.
Why Swimming Is Still Banned (and Why It Matters)
There’s a reason the City of Austin banned swimming here in 1964 after decades of drownings. Despite shoreline improvements (which are still going on to this day) and amazing amenities around the Trail, the water itself remains dynamic and dangerous.
An inter-departmental memo to City Council recently recommended keeping the ban in place due to persistent safety risks and the prohibitive cost of making even a small area swimmable.
Bottom line: Conditions can change fast and can trap even strong swimmers. This isn’t scare tactics - it’s about making informed, safe choices.
The Core Hazards You Can’t See
Underwater debris
Floods and bridge projects can leave behind tangled rebar, trees, and construction materials below the surface - exactly where you won’t see them.

Unpredictable currents
Historic submerged dams and occasional dam releases create surges and undertows that don’t match what the surface looks like.

Low visibility + sharps + trash
Urban runoff reduces clarity and can carry glass, metal, and other debris. Even when the water meets recreational standards, visibility is often poor.

“Unfixable” in practice
A 2020 Watershed report affirmed these hazards. City staff say they’re largely unfixable at the scale of Lady Bird Lake.

Water Quality: It’s Not Just About Clarity
Most days, Lady Bird Lake meets recreational standards. But algae toxins - specifically cyanotoxins - can pop up unpredictably. Since 2019, at least six dogs have died after exposure here. Humans are not immune.
Pet parents, please read this twice: Do not let your dog swim here. I wouldn’t let Cooper Goodman in this lake. Period.
“What If We Just Open a Small Swim Zone?”
City staff priced two of the least risky potential sites - and the numbers are eye‑opening:
- Deep Eddy Pool Shore
• $11 million upfront
• $4.5 million annually to operate - Fiesta Gardens Lagoon
• $17 million upfront
• $4.5 million annually to operate
Safer, Legal Alternatives (That Locals Love)
- Barton Springs Pool – Cold, clear, lifeguarded, and managed. Iconic for a reason. Personally, it’s still too cold for me. I have friends who absolutely love it.
- Lake Austin – Legal swim spots with different risk profiles. Always use life vests and common sense. Dumb is not highly favored in lake waters.
- Lake Walter E. Long – Another solid choice for lake days where swimming is actually allowed.
Quick Safety Checklist for Austin Waters
- ✅ Swim only where it’s legal and lifeguarded.
- ✅ Keep dogs out of Lady Bird Lake; rinse pets after any natural-water play.
- ✅ Treat clarity and currents with respect - even strong swimmers use life vests in lakes.
- ✅ After big storms, give waterways time to settle.
- ✅ When in doubt, Barton Springs.
Isn’t the water fine most days?
Meeting recreational standards isn’t the same as being safe for open-water swimming. Debris, currents, and visibility are separate hazards.

Can I wade from the shore?
No - the ban covers swimming and wading in Lady Bird Lake. Stick to boats, boards, and banks.

What about my dog?
Please don’t. Cyanotoxins have been linked to multiple dog deaths since 2019.

Will the City ever open a swim beach here?
Never say never (insert Justin Bieber circa 2010), yet current staff guidance and cost estimates suggest not anytime soon.

Final Word
Lady Bird Lake is one of Austin’s most-loved backdrops. Let’s enjoy it the safe way - from a board, a boat or (my fave) the trail. For an actual swim, head to Barton Springs, Lake Austin, or Lake Walter E. Long.
