Overall, dry conditions persist for most of Iowa. Precipitation average for the past two weeks has been 0.76 inch — a half inch less than normal.
The continuing drought is reflected in the change of stream flows across the majority of the state. The lowest conditions are in the Raccoon and Des Moines river basins, which have less than 10 percent of normal stream flow.
Shallow groundwater levels are lower in southwest, west central and south central Iowa. Adequate spring rainfall will be critical to recharge the alluvial and shallow bedrock aquifers.Conditions are close to normal for northeast Iowa, which had near normal rainfall during the past two weeks.
