CRYSTAL LAKE – The Crystal Lake Park District plans to treat Crystal Lake with a herbicide to help control invasive aquatic plants.
Lake management firm Hey and Associates will treat the area in the north cove of the west end, between the inlet channel and the point, with a granular herbicide called Hydrothol 191. The active ingredient is dimethylalkylamine salt of endothall, according to a news release from the Crystal Lake Park District. It will be applied to curlyleaf pondweed and eelgrass.
There are no swimming or fishing restrictions associated with the treatment, which is scheduled for Tuesday.
