Ice jam and snowmelt flooding continued over much of central Iowa during the last two weeks of March.  The South Skunk, North Raccoon, and Ice Rivers were the most affected.  Ice jams, while not severe, caused substantial difficulties with river gaging equipment and made forecasting a challenge as well.  The last two weeks of the month saw an almost ideal snowmelt regime, with very gradual melting of the large snowpack and very little precipitation.  This also helped to mitigate the potential effects of ice jams by keeping flows down.  By months end, continuous snow cover had retreated to the northern tier of Iowa counties, although many drifts and piles of snow remained in the north half of the state.  Several river flood statements were issued on the 30th and 31st as rivers across most of the HSA were beginning to go into flood.  Flooding across the HSA was all quite minor and continue as we moved into April.
