|Episode Narrative||Accumulating snowfall across the Upper Midwest and Northern Plains was extensive during the 2009/2010 winter with snowfall water equivalent amounts across the Minnesota River Valley as high as six inches. Across the Mississippi River Valley and the Crow, snowfall water equivalent amounts were between three and five inches.
The winter had very little melting on the snow cover and therefore, once temperatures in March started to rise and melt the snow cover, there was nearly three to six inches of liquid water ready to be release onto the surface.
The second week of March began with temperatures rising into the 40s and 50s.
A Flood Watch was issued as early as March 10th on the South Fork Crow River affecting Mayer in Carver County.
The first river flood warnings were issued on March 11th for the Minnesota River at Montevideo, Henderson, and Savage. Also, the Crow River at Rockford, and the South Fork Crow River below Mayer, and at Delano. On the 12th, other river flood warnings were issued along the Minnesota River, and the Cottonwood River at New Ulm.
The first flood warning for an ice jam was issued on the 12th for portions of Scott County on the Sand Creek. Other ice jams developed in Scott County on the 13th along the Credit River in Savage. Numerous ice james developed between the 13th and 18th when the rivers started to break up across southern and central Minnesota.
Damage from the flood waters was mainly confined to ice jam debris, and washed out county roads due to the fast flow and eroding the ground soil underneath the asphalt.
|Event Narrative||An ice jam formed along the Sand Creek, south of 173rd Street, and west of Highway 169 in Jordan.|
