All licensed beaches on the 13 lakes in McHenry County are tested every 2 weeks for E. coli throughout the summer to determine water quality. Additional and more frequent sampling is done when elevated bacterial levels are found. MCDH recommends refraining from swimming at least 2-3 days after heavy rainfall.

Water sampling results are reported to the appropriate beach authorities. Beaches that require an advisory or closing are posted with signs by MCDH. All beach water results and locations are readily available at the Department’s webpage at www.mcdh.info, by phone 815-334-4585 or email health@co.mchenry.il.us.
