Dozens of National Guard soldiers from around North Dakota are helping out in Pembina County, where recent heavy rains have led to flooding problems.
The soldiers are working rotating 12-hour shifts to support Cavalier, which was evacuated because of a threat to the Renwick Dam on the Tongue River west of the city.
State Guard commander Maj. Gen. David Sprynczynatyk (sprihn-suh-NAT'-ihk) says the Guard has plenty of experience in such situations. Soldiers have helped out with major flood battles around the state in recent years. They also came to the aid of the southeastern town of Kathryn in 2009 when a dam near that town was threatened by floodwaters.
