Nearly 90 percent of Iowa’s land is experiencing a drought of differing degrees due to low levels of precipitation in May.

32 percent of the state rated abnormally dry, 47 percent is in a moderate drought, and 10 percent received a severe drought rating according to the most recent U.S. Drought Monitor map. Precipitation in May was more than an inch below average this year. The Iowa Department of Natural Resources reported on Thursday that the statewide average was 3.71 inches, ranging from 1.95 to 8.53 inches across Iowa. The start of June also saw a below average rainfall, dragging drought indicators lower.

The warm and dry conditions in the last month mixed with a below-average rainfall has expanded the land impacted by drought conditions. Northern Iowa saw drought conditions increase to cover two-thirds of the top half of the state according to the report. Southern Iowa saw similar levels of drought expansion as well.

Current weather conditions led to “below normal” stream-flow conditions across half of Iowa. Several river basins in the state are seeing lower flows, but portions of the Raccoon and Des Moines river basins have “much below normal flows”. The decrease could lead to about 69 percent less runoff than normal at the Missouri River basin above Sioux City, the report said.

As of June 10, only southeastern Iowa is free of drought and abnormal dryness conditions.
