In June, the Rapidan Dam near Mankato, Minnesota, partially failed and millions of cubic yards of sediment trapped behind the dam for a century flowed into the Minnesota River. The effects of this dam breach won't be known for months or years, but it already forced a closure of the navigation channel in Savage in September and the Army Corps of Engineers had to remove three times the amount of sediment that they normally remove in a year. Big River Magazine called me and asked me to write an article about this. I submitted that article this week and it will appear in their March-April issue along with the Fifth Principal Meridian article I discussed earlier.
