Butler Lake Update


Butler Lake is an active
eco-system that requires regular management during typical conditions, and alsowhen weather changes the normal balance of growth.   The Village retains,
Clarke Aquatic Services, to manage the lake vegetation during the summer monthsand they recently treated the water lilies and coon tail.  The resulting
vegetation dieback reduced the dissolved oxygen levels, which was believed tohave adversely impacted the fish population.  No applications to the lake
directly harmed the fish.  Village Parks Maintenance staffhave been and will continue to remove the fish that have perished.  The
Illinois Department of Natural Resources (IDNR) is fully aware of the situationand investigated the lake and the fish situation earlier in the week.  The
IDNR indicates that this happens from time to time when a body of water isoverpopulated with vegetation.  The IDNR and the Village will continue to
monitor the fish variety and population.  The dead vegetation will sink tothe bottom and decay and the dissolved oxygen levels will normalize.
