What happens at each level
- 12.50 ft
Unusually high river stage for this reach of the Missouri River. Residents are encouraged to pay close attention to NWS updates, local media, and local emergency management for information concerning why the river is this high and its potential for further rises.
- 14.50 ft
Flooding of rural areas begins. Inundation of croplands and the potential closure of local boat ramp access is likely. Riverbank erosion rates increase and cause unstable shorelines. If water levels are the result of an icejam south of Bismarck, water levels will be relatively higher near the jam and cause concerns for residents south of Fox Island.
- 16.00 ft
Before 16 feet, older homes in the Fox Island area may experience flooding. Homes built to this level are at less risk but may have water surrounding them. Access to Fox island is difficult because of water on Riverwood Drive. No significant threat to the incorporated cities of Bismarck and Mandan.
- 17.00 ft
City of Bismarck experiences flooding of streets in low-lying areas if not protected. Access to Fox Island and other rural developments becomes increasingly difficult.
