Why Are Some Lakes Not Suitable for Swimming in Louisiana?

There are many reasons why some lakes in Louisiana are unsuitable for swimming, and some may surprise you. Here are some of them:

1. Chemical Contamination

Chemical contamination is a primary factor contributing to the unsuitability of several lakes in Louisiana for swimming. Such contamination can stem from various sources, including industrial spills, agricultural runoff, wastewater discharge, or natural occurrences like mercury deposits. This pollution significantly impacts water quality and poses potential health hazards to humans and wildlife. Mercury can accumulate in fish and trigger neurological impairment when ingested in large quantities.

2. Harmful Algal Blooms

The emergence of harmful algal blooms (HABs) has rendered some lakes in Louisiana unsuitable for recreational swimming. These occurrences entail surges of algae that secrete toxins or diminish oxygen levels in the water, causing fatalities among fish, repulsive odors, and various health-related issues for animals and humans. Nutrient pollution, elevated temperatures, etc., typically cause HABs. Symptoms of HAB exposure may encompass skin irritation, ocular discomfort, respiratory distress, nausea, emesis, diarrhea, and hepatic damage. Notably, various lakes in Louisiana, including Lake Pontchartrain and LSU University Lakes, have encountered HABs.

3. Alligators

Alligators are indigenous to Louisiana; they’re in virtually every freshwater environment. With the potential to attain lengths of up to 15 feet and weights of up to 1,000 pounds, alligators are opportunistic predators that prey on fish, turtles, birds, mammals, and humans on rare occasions. Although rare, alligator attacks typically result in death. At least 2 million alligators are found in Louisiana, and incidents of swimmers being attacked in lakes are common.

4. Snakes

Louisiana harbors 47 types of snakes, among them seven venomous ones: pygmy rattlesnake, Texas coral snake, timber rattlesnake, eastern diamondback rattlesnake, cottonmouth (otherwise known as water moccasin), copperhead, and the eastern coral snake. These reptiles occupy different territories close to water sources, like bogs, swamps, timberlands, fields, and trenches.

Their instinctual protection mechanisms might incite them to nibble when they see danger or incitement. Side effects of venomous snake bites might incorporate, but not restricted to, uneasiness, swelling, vomiting, bleeding, redness, sickness, discombobulation, and respiratory trouble. Swift and appropriate treatment is imperative to avoid fatalities.

5. Leeches

Leeches are parasitic worms that can attach to their hosts’ skin or mucous membranes and feed on their vital fluids. Typically found in stagnant or slow-moving waters with plentiful vegetation or organic matter, these creatures threaten human health by inducing sensations of itching, burning, inflammation, infection, and allergic reactions. Furthermore, leeches can transmit an array of diseases to their hosts, including but not limited to bacterial infections and anemia.

6. Brain-Eating Amoeba

Certain lakes in Louisiana are infested by Naegleria fowleri, commonly known as brain-eating amoeba. This minuscule organism thrives in warm freshwater and soil. It can infiltrate the human body through the nasal cavity during aquatic activities in contaminated water. Once inside the body, it migrates to the brain and triggers an infrequent yet perilous infection called primary amebic meningoencephalitis (PAM), which induces a severe headache.

7. Water Depth

Certain lakes may not be ideal for swimming due to their respective depths. For instance, shallow lakes may conceal submerged hazards, such as rocks, stumps, or debris, which can potentially cause injury to swimmers. Conversely, deep lakes may feature strong currents, chilly temperatures, or reduced visibility, posing challenges or hazards for swimmers.

8. Water Access

Certain bodies of water in Louisiana are either under private ownership or supervised by state and federal agencies that may impose specific protocols or restrictions on swimming activities. A prime instance of this is Lake Bistineau – a state park with two swimming pools. However, taking a plunge in the lake is prohibited per the governing regulations.

What Are the Safety Precautions to Take While Swimming in Louisiana Lakes?

Here’s a list of seven safety measures swimmers should adopt to avert any mishap while taking a dip in Louisiana’s lakes:

1. Check for Advisories

Before you visit the lake, we recommend that you ascertain the existence of any fish consumption or swimming advisories that might have been released by the Louisiana Department of Health (LDH) or the Louisiana Department of Environmental Quality (LDEQ). 

These advisories serve to caution you against potential exposure to pollutants such as mercury or organic chemicals in select water bodies and furnish guidance on permissible levels of fish intake or frequency of swimming. The advisories are accessible on the LDH website or through the interactive map featured on the LDEQ website.

2. Avoid Swimming after Heavy Rains

When it starts pouring, all sorts of filth get dumped into waterways. Sewage overflows, stormwater runoff, agricultural runoff, and animal waste flush harmful pollutants, bacteria, and parasites straight into water bodies. These microorganisms can lead to infections and illnesses like diarrhea, nausea, vomiting, skin rashes, eye irritation, and ear infections. To mitigate the likelihood of exposure to these contaminants, we recommend abstaining from swimming in zones marked with cautionary advisories or after downpours.

3. Avoid Ingesting or Swallowing the Water

Although the water might appear crystal clear and pristine, it could still harbor dangerous bacteria and toxic substances that may inflict illness upon you. To avoid swallowing or taking in the water unintentionally, keep your mouth shut while swimming, refrain from submerging your head underwater, and steer clear of drinking from the lake. Should you feel dehydrated, bring your bottled water or use a filter or purifier to treat the lake water before quenching your thirst.

4. Avoid Swimming with an Open Cut or Wound

An open wound or cut can invite nasty bacteria and parasites to invade your body. And some of these infections can pack a punch, like the dreaded flesh-eating disease or a bacterial infection called vibriosis. To stay safe, steer clear of swimming with an open wound. However, slap on a waterproof bandage if you can’t resist taking a dip. Once out of the water, hop in the shower and give yourself a good scrub down. Remember to clean and disinfect that cut as soon as possible!

5. Protect Your Skin

Exposure to the sun’s UV rays can harm your skin and heighten the likelihood of developing skin cancer. To shield your skin from getting scorched or sunburnt, slather on a broad-spectrum sunscreen having a minimum SPF of 15 before taking a dip. Reapply it every two hours or when you sweat. Don a cap, sunglasses, and protective attire that cover your vulnerable skin. If possible, seek refuge under a shade and steer clear of swimming during peak sunny hours (from 10 a.m. to 4 p.m.).

6. Watch for Motorboats, Jet Skis, and Other Lake Users

While swimming in a lake, it’s possible to run into people maneuvering watercrafts such as motorboats, Jet Skis, kayaks, canoes, and paddle boards. These conveyances can be risky for swimmers if they’re not cautious. To avoid collisions and mishaps, be alert for motorboats, Jet Skis, and other lake-goers, and avoid crossing their paths. Please don’t presume they can detect your presence or hear your calls. Make yourself visible by donning a brightly-colored swimsuit or swim cap.

7. Always Have Adult Supervision

Taking a dip in a lake is a challenging feat compared to a controlled pool environment. The ripples, currents, depth, temperature, visibility, and wildlife all make it riskier for anyone who isn’t a seasoned swimmer. 

So, if you’re planning to swim in a lake, ensure you’ve got an adult companion keeping an eye out for you, especially if you’re a kid or have any medical conditions. Never take the plunge all by yourself or push beyond your limits. Knowing how to swim and having a few water safety tricks up your sleeve, like floating, treading water, and signaling for assistance, is essential.

Enjoying Louisiana’s Lakes Safely and Joyfully

Louisiana has abundant lakes ideal for outdoor activities like swimming, boating, and fishing. These glistening water sources present a rejuvenating respite from the scorching heat and busy urban existence. Nevertheless, as with any body of water, it’s imperative to prioritize safety and comply with the guidelines and protocols established by each lake. This guarantees an enjoyable experience for all parties involved without any unforeseen misfortunes.
