Climate experts: All dryness has left Iowa
for the first time in more than four years — have sufficient soil moisture to not be considered “abnormally dry” by national climate experts, according to a U.S. Drought Monitor report released last week.
That dryness designation can indicate an area is on the cusp of drought conditions, under which affected areas can have negative impacts for agriculture and water supplies.
An example: After years of drought, a lake that supplies water for the city of Osceola had lost so much of its volume that the city considered recycling its wastewater. Significant rainfall in recent months has restored the lake to nearly its normal surface elevation, according to city data.
Drought developed in Iowa in July 2020 and persisted until May 2024, after the state had one of its wettest starts to a year on record. It marked a dramatic recovery since September, when the state was the driest it had been in a decade.
Last week, Iowa had rainfall that was below average, according to State Climatologist Justin Glisan. However, heavy rain fell along the eastern edge of the state where the last remaining pocket of abnormal dryness lay.
A month ago, about 31 percent of the state was abnormally dry, according to Drought Monitor reports. The last time there was no drought or dryness was May 2020.
The federal Climate Prediction Center does not foresee drought reemerging in Iowa in the coming months. Iowa lies in the center of a multistate area that has no drought and little abnormal dryness.
The U.S. Department of Agriculture reported last week that more than 90 percent of Iowa’s farm fields have adequate or surplus moisture for growing crops. Last year, only 57 percent of topsoil was rated the same way.
