Adding to the concern, Hurricane Irma is projected to pass over Lake Okeechobee, which could push water over the top of the lake's 30-foot-tall dike. It's a scary thought, since the lake's dike is one of the country's most at-risk of failing. To witness Katrina-like flooding from another dike failure would be too much to bear. Gov. Rick Scott was right to order the evacuation of lakeside communities.
