| Episode Narrative |
The Missouri River, which had been near flood stage in many areas, began a significant rise near the end of the month in response to widespread upstream heavy rain which fell after unusually large upstream snowmelt. Flooding reached the moderate category by the end of May with the river on the way up across its length. |
| Event Narrative |
Flooding along the Missouri River developed and then increased in late May as runoff from excessive upstream snowmelt and rain reached the area. Lowlands flooded included camping and other recreational facilities, as well as some roads. |
