minnesota river flooding

We have had rain several times per week for the past month. The rivers and lakes are high, and several communities have flooding problems. I just stopped by the Minnesota River and saw the sign in the photo below. It caught my eye because the sign is usually several feet above the water level, and also because the reference is to the flood of 1965 which is one full section of my book Historic Disasters in Southeast Minnesota. Several roads, bridges, and businesses in Minnesota are closed right now and the rains just keep coming.
