Snowmelt and 2-3 inches of rain last weekend (March 27-28) in North Dakota and Minnesota led to this unusual early spring flood event.
The daily flow for today (March 31) at Grand Forks will be one of the top three highest flows for this early in the spring season since flow record keeping began at Grand Forks in 1904 (Table 1).
This early spring season runoff was especially unusual in that the heaviest runoff within the Red River basin occurred downstream (north) of Grand Forks.
