Episode Narrative The winter of 2010-2011 generally brought above normal amounts of snow to the area, but particularly so for the Devils Lake basin, the Sheyenne River basin, and the Wild Rice River basin. By April 1st, snow water equivalents were estimated to be about four to six inches in these areas with about two to four inches elsewhere. A see-saw pattern of temperatures led to a generally slow April snowmelt. At Fargo, the first six days of April averaged near normal for temperatures. The next six days averaged above normal, which led to some snowmelt. From the 13th through the 23rd temperatures swung back below normal along with several days with additional snow. At Grand Forks, the temperatures ranged a bit different than at Fargo. The first 12 days of the month were above normal, then the 13th through the 22nd were below normal. The snow disappeared first in the northern Red River Valley, while it took longer to melt in the other areas. Devils Lake started rising in early April from its winter level of about 1451.80 feet MSL. By the end of the month the level has risen to about 1453.60 feet MSL, a modern day record. Due to overland flooding, hundreds of roads were also closed across the area.
