Warm weather last week caused the loss of the ice on the Missouri
River through the Bismarck and Mandan area. However, colder weather
along with snow earlier this week has created sufficient ice moving
downstream to once again fill in the river channel.

Since early Wednesday morning, ice has been collecting in the Fox
Island area and restricting flow on the Missouri River. Water has
been backing up on the Fox Island boat ramp parking lot. As ice
continues to collect, increasingly higher water has, and will
continue to move northward through the Bismarck and Mandan reach of
the Missouri River.

The river stage at the onset of this ice jam was 9.6 ft as measured
at the Bismarck gage on the Missouri River. Water levels due to ice
jams are difficult to predict, but given the starting water
elevation, and the current stage of 13.1 feet as of 8 PM, Wednesday
at the Bismarck gage, there is a real risk of it reaching flood
stage of 14.5 feet.

If you observe problematic high water, please report your
observations to your local emergency management office.
