The Big Sioux River levels continue to decrease.  Because of this the National Weather Service is not providing projections on how the river levels will change over the next week.  The river is below action stage and at approximately 26.5 feet.  We can expect to see some increase to the water most likely around the 27-foot river level.  The City will continue to monitor the flows in the Big Sioux and at this time the crest in Dell Rapids was approximately 1 foot below what the projections showed.  The river levels at Dell Rapids have plateaued and will remain at these levels until Monday.  Most of the snow melt has occurred South of Brookings.  The Watertown area will continue to melt this week with temperatures forecasted in the 60s.  This is very positive news for North Sioux City.

Currently Gavin’s Point Dam is releasing water at 33,000 cubic feet per second.  This is expected to increase today to 36,000 cfs tomorrow and the plan is to hold at that level until April 9th.
