Blue-Green Algae In Brookville Lake

(Brookville, Ind.) – Toxic algae is posing a threat to swimmers in some of Indiana’s public waterways.

The Department of Natural Resources says there are record high levels of blue-green algae being seen this year. Brookville Lake is among the waterways seeing the higher levels, with higher than normal counts at the Mounds State Recreation Area and Quakertown State Recreation Area.

Heightened algae levels have already proven fatal for two dogs who swam last week at Salamonie Lake. Dogs and other animals are particularly vulnerable to blue-green algae because they may drink the contaminated water or swallow the algae as they clean their coats. 

Two dogs in central Indiana died after coming into contact with the algae.

The DNR says the summer heat, fertilizer, and animal runoff from livestock farms all contribute to blue-green algae growth. Drought and low water levels in lakes and reservoirs can increase blue-green algae quantities and toxins. 

People who come in contact with the algae or its toxins may develop rashes, skin and eye irritation, nausea, stomach aches, and tingling fingers and toes. Anybody who experiences the symptoms after boating or swimming should seek medical attention. 

The DNR provides these tips for avoiding poisonous algae:

Avoid ingesting lake water.

Avoid contact with algae blooms, which generally appear as a scum on the water surface.

Shower with soapy water after swimming.

Bring clean water for your dog to drink on hikes or other outings.

Keep dogs close and on a leash.

Bathe your dog with soapy water as soon as possible after a swim.
