N.D. (AP) – Flooding caused by days of heavy rain in northeastern North Dakota has affected three communities and a couple of highways.

In Pembina County, the 1,300 people in Cavalier have been evacuated as officials work to shore up the Renwick Dam on the Tongue River to the west of the city. Some of the 160 people in Crystal have voluntarily left their homes due to floodwaters moving overland through the town.

In Walsh County, officials in Grafton have shored up an emergency levee as the Park River nears a record crest there. About 4,500 people live in the city.

The state Transportation Department says state Highway 18 is closed at Neche (NEE’-chee) due to water on the roadway. State Highway 18 into Cavalier also is closed due to the flood operations.
