Pokagon State Park has temporarily closed its Main Beach after routine water quality testing revealed elevated levels of E. coli bacteria exceeding state safety parameters.
The Indiana Department of Natural Resources (DNR) announced the immediate closure to protect public health after samples surpassed Indiana's threshold of 235 colonies per 100 milliliters.
Park officials attribute the sudden spike in bacteria to heavy rainfall, which frequently triggers an influx of nutrient-heavy stormwater runoff from nearby agricultural areas and local septic systems into Lake James.
Warning signs are prominently posted along the shoreline, and guests are strictly advised to avoid swimming in the area due to potential health risks like gastrointestinal distress. While the Main Beach remains offline for further lab analysis, all other park amenities—including hiking trails, boating, and fishing remain fully accessible.
Visitors looking to swim are being redirected to alternative nearby locations, such as the Potawatomi Inn Beach or the designated swimming area at the Trine State Recreation Area.
