What impacts water quality?
Water quality can change based on the weather and environment. Common factors include:
-
Rain runoff: Stormwater carries bacteria and pollution into the lake.
-
Bird droppings: Ducks, geese, and seagulls are frequent contributors to bacteria.
-
Warm temperatures: Bacteria grow faster in hot water.
-
Other risks: Debris, algae blooms, or spills may also make water unsafe.
Tip: Avoid swimming for 48 hours after heavy rain or strong winds to reduce your risk of exposure to harmful bacteria.
Why do we test beach water?
We test for E. coli bacteria to make sure swimming is safe. High levels of E. coli can cause:
-
Stomach upset (e.g., diarrhea, nausea)
-
Skin irritations or infections
-
Eye, ear, nose, or throat problems
Testing helps keep you and your loved ones safe while you enjoy the water.
How can you stay safe at the beach?
A few simple precautions can make your beach day safer:
-
Don’t swallow lake water
-
Shower after swimming
-
Avoid swimming if you have cuts, open wounds, or aren’t feeling well
-
Stay out of the water if it looks murky or unclear
Remember: Check conditions before swimming and avoid the lake after heavy rain or wind.
