MINNEAPOLIS (AP) — The drought in Minnesota continues to get worse, exposing rocks, riverbeds and islands in the St. Croix and Minnesota river drying up entire channels in the mighty Mississippi. The Minnesota Department of Natural Resources has imposed water restrictions for much of the state. Utilities are to limit water use to no more than 25% above January levels. The restrictions apply to about 300 communities within three major watersheds which include the Mississippi River Headwaters and the Rainy River and Red River. That covers the Twin Cities, nearly all of central Minnesota and much of northern Minnesota.
