Above normal rainfall was received over the last two weeks — the statewide average was 2.3 inches compared to the normal 1.7 inches. However, more slow steady rains are needed.
Although shallow groundwater levels in southern central, eastern and northeastern Iowa have benefitted from the rainfall, parts of southwest and northwest Iowa received very little rain and shallow groundwater levels are much lower than the previous April.
Water supply operators in northwest Iowa are seeing reduced production, dropping water levels and historically low levels.
