...ICE JAM FORMING ON MISSOURI RIVER... 



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.



As of 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 will 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, an eventual stage of at least 12.5 ft at the Bismarck 

gage is not unreasonable to expect.



If you observe problematic high water, please report your 

observations to your local emergency management office.
