...Ice Formation On Missouri River Near Bismarck...

The recent cold weather has lowered the water temperature
sufficiently to form ice on the Missouri River in the Bismarck
and Mandan area. Sheets of ice are moving downstream and into
Lake Oahe as there is no continuous ice cover on the lake.
Historically, the ice has been known to collect in the river bends
near the University of Mary and create rapidly rising water in the
Bismarck and Mandan area as ice cover encroaches northward. The
Missouri River has come up about 0.6 feet over the past 24 hours
at Bismarck to reach a stage of 4.3 feet as of mid day Wednesday.

As the weather forecast calls for continued below normal
temperatures well into the middle of December, ice formation will
also continue. The Missouri River should rise between 4 and 7
more feet as it becomes fully covered in ice.

People along the river should be prepared for rapidly rising
water even though actual damaging high water this time of year is
rare. Any instances of damaging high water should be reported to
your local emergency management officials.
