With this being the Labor Day holiday weekend the Oklahoma Department of Environmental Quality is cautioning those planning a trip to the state's many lakes, rivers, or streams to be cautious.
The DEQ says certain bacteria, viruses and protozoa can be present in untreated bodies of water. And some of these microorganisms occur naturally while others are carried into surface waters from a variety of sources.
Some of these microorganisms are harmful and can cause mild problems such as ear infection or relatively rare but serious conditions such as eye infections and some forms of meningitis.
In July, the state Department of Health said a young boy died from a waterborne illness caught while swimming in the Red River.
The DEQ says swimmers should pay close attention to water conditions. Also, it is important to pay attention to posted signs when swimming in any body of untreated water. Another big concern is green algae.
The state Department of Tourism suggests boaters and swimmers check out the web site www.travelok.com/checkmyoklake before heading out this holiday weekend.
