Although the summer is coming to an end, lake safety workers are stepping up efforts to educate swimmers about ways to stay safe.

Earlier this summer, two people died of amebic meningitis after swimming in Lake LBJ. This week, the Lower Colorado River Authority will begin putting up signs and handing out flyers to help raise awareness of the risks of swimming in lakes in rivers.

The signs will be put up at public-access points at lakes Buchanan, Inks, LBJ, Marble Falls, Bastrop, Fayette, and Lake Travis. The LCRA is hoping to warn people about possible hazards, from drowning and boating accidents to potentially deadly illnesses.

Lake Travis is a popular spot for boaters.

“We've been out here for three days just taking it easy, kicking back, and vacationing,” said Joshua Alexander, a boater.

It's what happened on Lake LBJ earlier this summer that's prompting some changes on area lakes. In August, a 12-year-old Travis County boy died from amebic meningitis after swimming in Lake LBJ. Nearly a month later, a 22-year-old man also died from the same thing after swimming on the same lake.

“Something has to be done,” said Melissa Brown during an interview earlier this month. She lost her son, Brandon, to amebic meningitis two years ago after swimming on Lake Somerville.

“How many more children are we going to have to lose before something is done,” said Brown.

“We had been receiving a lot of calls from the public, area businesses around the lakes and there seemed to be just a general lack of awareness of this common amoeba and this rare disease that it causes,” said Krista Umscheid, a spokesperson for LCRA. She says it will soon put up more than a hundred signs and hand out fliers, warning swimmers and boaters about the risks.

The signs will warn swimmers to hold their noses when diving or jumping into the water, use earplugs or goggles to minimize risk of infections, wash open cuts and scrapes, wear a life jacket, not to dive into shallow water, and always swim with a partner.

“We didn't want to just put a water-related illness warning out because then you would be diluting some of the other water safety messages such as drownings,” said Umscheid.

It's a warning that boaters like Joshua Alexander will heed.

“If there weren't signs, then people wouldn't know what was going on,” said Alexander.

The signs could be up as early as Friday.
