DeWitt Park Beach on Silver Lake is closed to swimming and Hooker Lake boat launch and Paddock Hooker Lakes Association beach on Paddock Lake are under a swim caution after sampling by Kenosha County on Monday found elevated E.coli levels there.
The State Department of Health recommends posting warnings at beaches when test results indicate an E.coli level of 235/100mL or more and closing a beach when test results exceed E.coli 1000/100mL.
The results from Monday that prompted the above actions were:
- DeWitt Park beach — 1553 E.coli/100 mL
- PHLA beach — 260 E.coli/100 mL
- Hooker Lake launch — 517 E.coli/100 mL
The above location are scheduled for resampling. Typically that takes place the next day, weather permitting.
