(Hidden Valley, Ind.) - A small lake in Hidden Valley may be affected by blue-green algae.
Kathy Lake along Fieldcrest Drive has tested for possible contamination of the toxic algae also known as cyanobacteria. Test results are pending.
The HVL Property Owners Association is warning people and pets not to swim, boat, drink from, or eat fish from Kathy Lake.
Other lakes in Hidden Valley are not affected.
Exposure to blue-green algae can cause rashes, skin, eye irritation, and effects such as nausea, stomach aches, and tingling in fingers and toes, the Indiana Department of Natural Resources says.
According to the Indiana Department of Environmental Management, "Algae are commonly found in Indiana lakes and streams without concern, however the concentrated presence of blue-green algae can be linked to some adverse health effects. Factors promoting algal growth include sunlight, warm weather, low turbulence, and nutrient sources, such as phosphorus and nitrogen. Phosphorous is particularly important in fueling cyanobacteria growth. Often nutrient inputs come from nonpoint source pollution, but fortunately, there are many ways to reduce or stop nonpoint source pollution, many of which are simple things we can do right in our own backyards."
