DES MOINES-Prior to the night rains of July 25, Iowa averaged only 0.37 inches of rain, much less than the normal two inches for July. All of the state is in some form of drought, with over a quarter of the state in extreme drought. That is the greatest area of that designation in Iowa since the National Drought Monitor was developed 12 years ago.
Streamflow conditions reflect the heat and lack of rain. The lowest streamflow conditions are found in the Skunk River, Des Moines River, Iowa River, Wapsipinicon River and the lower Cedar River basins, all less than 10 percent of normal streamflow. Streamflow conditions in northwest Iowa have normal flows.
