More than seven inches fell from Sunday night through Monday in the Iowa Great Lakes area, causing lake levels to approach records. Dickinson County Emergency Management has implemented a 5 MPH rule for all watercraft as of Tuesday afternoon. Captain Greg Harson of the DNR Law Enforcement Bureau says they hope to reduce the wake impact against the shoreline.
Harson says the change from drought to excess rain has already impacted boaters as docks are underwater.
The record flooding levels happened back in 2018. Dickinson County Emergency Management reports that Big Spirit Lake and East and West Okoboji are about a half foot away from that level as of Tuesday morning.
