BISMARCK, N.D. (AP) — A rising Missouri River in the Bismarck-Mandan area has some residents nervous, but the National Weather Service says there's little risk of major flooding.

KXMB-TV reports the river is the highest it's been since July 2011. Flooding that year caused property damage, forced some people from their homes and led to a large-scale sandbagging operation.

Heavy spring snowmelt and rains swelled the river that year. The rising river right now is due to snowmelt and ice jams, and meteorologist Ken Simosko says that's normal for this time of year.

The river is still a couple of feet below flood stage. Simosko says no significant flooding is expected — but he adds that residents should be "on the watch" until Wednesday, when the river should be fully open.
