BISMARCK, N.D. (AP) — A top state official warns that millions of acres of farmland will not produce anything this year due to flooding.

According to the Bismarck Tribune, North Dakota Agriculture Commissioner Doug Goehring estimates 6.5 million acres of land have been affected by flooding and rain.

Five counties in North Dakota have been approved for federal disaster aid: Burleigh, McHenry, Morton, Renville and Ward. Officials continue to monitor the Souris River, which has forced thousands from their homes in Minot.

Federal money will fund much of the eventual cleanup. But some are worried about requirements that losses be reported to some agencies within 30 days.

In some cases, damaged land remains underwater and can't be fully assessed.
