Island Lake beach shut because of bacteria

WOODSTOCK – A beach in Island Lake has been closed and there is an advisory at Main Beach in Crystal Lake because of high bacteria levels, according to a news release from the McHenry County Department of Health.

The health department Monday conducted beach water samplings at 37 licensed beaches. Dorothy Court (211 Dorothy Court, Island Lake) was closed because of high bacteria levels; Main Beach in Crystal Lake (300 Lake Shore Drive) is on an advisory.

Both beaches were resampled Tuesday. All other beaches are open for the July 4 holiday.

To prevent illness associated with swimming, all licensed beaches on the 13 lakes in McHenry County are tested every two weeks for E. coli bacteria throughout the summer to determine water quality.  Additional and more frequent sampling is done when higher levels of contamination are found.

Water sampling results are reported to the beach authorities.

The health department will post an advisory or closed signage for beaches with elevated E. coli results. All beach water results and locations are available at (click Environmental Health, quick links, “beach testing results”) or call 815-334-4585.
