I mentioned the rain that is forecast to come this week, painting a particular target on eastern Iowa, southeast Minnesota and western Wisconsin in my last update. Fortunately, the overlap with areas that have already seen too much rain this summer is not perfect. But there is still overlap, and the rain has caused some mighty problems for areas from the Siouxland of Iowa, South Dakota and Nebraska northeast through south central Minnesota.

In southeastern South Dakota, McCook Lake, an unconnected oxbow lake suddenly had water flowing into it from runoff and redirected flow, causing it to overspill its bank, and destroying property north of Sioux City. The rising water damaged cropland from Nebraska and South Dakota east through northwest Iowa and southwestern Minnesota. The towns of Windom, Jackson and Waterville were underwater, because of the Des Moines River in Windom and Jackson, and the Cannon River in Waterville. The above video shows the scene in the south Twin Cities metro, where Shakopee’s Valley Fair Amusement Park had to close some rides and lost use of their parking lot because the Minnesota has spilled its banks. And of course, we have all seen video of the rising water opting to circumvent the Rapidan Dam, with disastrous regional effects.

Fortunately, it was a dry weekend. Unfortunately, the week ahead doesn’t look that way. A few more successive waves in the northern Plains look to keep things cool and wet. The bullseye for wet weather is shifted a bit to the east, so the smaller creeks and rivers may not see repeat flood risks, but most of these waterways flow in the same direction. Eventually, there may be concern for Mississippi River towns from the Twin Cities on south.
