Wild Things: Dealing with Invasives
The Forest Preserve District of DuPage County recently reopened Deep Quarry Lake at West Branch Forest Preserve in Bartlett to boating, ending a ban ecologists had hoped would stop the spread of invasive zebra mussels. The District had discontinued recreational boating at the 40-acre lake when it discovered zebra mussels there in 2009. Despite the effort, though, zebra mussels continued to spread to the adjacent Bass Lake at West Branch in 2012, Mallard Lakes at Mallard Lake Forest Preserve in Hanover Park and Eagle Lake at Hidden Lake Forest Preserve in Downers Grove. The spread indicates the mussels were likely being spread by other means such as fishing.
