Dredges are working overtime to try and see barges moving on the Mississippi River and an underwater levy is being built to keep saltwater from intruding into local drinking water supplies now the Mississippi is at or pretty close to historic lows in some spots just because we’ve had a lack of rainfall this year especially in areas that feed the river the U.
