Your current coverage of the spring flooding in the Upper Midwest has ignored a basic fact. The Red River that forms the boundary between North Dakota and Minnesota flows north. That phenomenon has accounted for flooding during many past springs. Snow, ice and rains along its south end cause waters to rush northward where the river bed may be narrowed and clogged by unmelted ice. Then the water is forced out of the river bank.

The Red River (sometimes called the Red River of the North) does not feed into the Mississippi; it flows into Lake Winnipeg, about 40 miles north of Winnipeg.
