CHICAGO -- The water levels in Lake Michigan are rising at a near record rate.
Lake Michigan hit a record-low two years ago. Since then, it's risen more than 3 feet. Experts say that's an almost unprecedented rate.
It's been a good thing for commercial shipping, recreational boaters and wildlife. But, it's also threatened shoreline properties and caused beaches to erode.
Despite the resurgence, Lake Michigan is currently less than a foot above average.
