Ice jams are creating some minor flooding along the Heart River in northeastern Morton County approximately 10 miles upstream of Mandan.  The National Weather Service issued a flood warning for the area effective until 3:30pm tomorrow.

This afternoon, an ice jam created elevated water levels on the Heart River. The melting along the river from warmer temperatures can create rapidly fluctuating water levels both upstream and downstream of the jam, but cooler overnight temperatures should help slow the ice melt.

The City of Mandan Public Works, Morton County Emergency Management, Lower Heart Water Resource District and the Morton County Sheriff’s Office continue to monitor rivers, roads and bridges for rising water and are taking precautionary measures as needed.

County Road 82 between 51st and 54th Streets and County Road 140 north of Hebron are closed within Morton County due to flooding. Several other roads throughout the county have high water along the edges and motorists should drive cautiously. Ft. Lincoln campground is being monitored for rising water and any questions should be directed to park staff at (701) 667-6340.
