The March 1st blizzard, combined with very heavy snow from another storm on February 23-25, resulted in a snow cover of 20 to 30 inches over much of northern Iowa. Temperatures suddenly warmed after the 8th of the month over the south half of the state, and by the 9th and 10th across the north.  The snow pack held 3-5 inches of water and this would become a problem when temperatures warmed in the middle of the month.  The last of the snow cover did not melt until the 22nd.  Ice covered nearly all of the rivers and creeks in Iowa through the first part of the month, due to the very cold temperatures from February.  As temperatures warmed in March, melting of snow cover exceeded the melting of ice on the rivers, and the ice started to move.  Ice jams caused flooding along the Des Moines River from Estherville through Fort Dodge, and flooded some of the neighborhoods in Fort Dodge as it backed up streamflow on the Des Moines River on March 14th. Another ice jam would move down the Raccoon River, with flooding reported along Highway 169 near Adel.  This ice would bring moderate rises along the Raccoon River all the way to it���s confluence with the Des Moines River, however the effect on the Des Moines River was negligible, due in part to the Saylorville Reservoir.  General flooding was fairly widespread, however damage was limited fo r the most part.
