BISMARCK, N.D. (AP) - Federal authorities are encouraging people in North Dakota and South Dakota to watch out for quickly changing ice conditions on all reservoirs in the states.
The U.S. Bureau of Reclamation says winter snowpack that's melting due to warmer than normal temperatures has increased water inflows enough to cause rapid shifts in ice conditions.
Dakotas Area Office manager David Rosenkrance says the changing water elevations and increased runoff create thin ice that makes rivers and lakes unsafe. He says the elevations change the ice conditions with no warning.
