The Health Department informs me that an employee will test Main beach on Saturday.

The results will be on the front page of the department’s web site.

Crystal Lake Park District Executive Director Jason Herbster writes,

“This is a day to day situation so I cannot say if Main Beach will be open or closed. The County Health Dept. will test every day until the levels are back in the acceptable range. Water fowl are typically the cause of this situation.”
