(Brookville, IN)--If you’re planning on spending a part of the Labor Day weekend at one of the Brookville Lake beaches, you may have to make other plans. Beaches were closed Tuesday after water testing revealed high levels of E. coli in the water. The E. coli is not at all related to high levels of blue-green algae that have been found in large area lakes this summer. There’s no word on how long the beaches will remain closed. Officials at Brookville Lake say it may be a sampling error.
