Rainfall in the last part of August helped to lift many parts of Iowa out of drought conditions, but some parts of the state are still experiencing extreme drought, according to the latest Water Summary Update.
The Water Summary Update is a succinct monthly report of Iowa’s water resources and those events that affect them prepared by the technical staff at Iowa DNR, the Iowa Department of Agriculture and Land Stewardship, IIHR—Hydroscience and Engineering, and the U.S. Geological Survey, in partnership with Iowa Homeland Security and Emergency Management Department.
The latest summary revealed that while August started off very dry, high rain totals increased groundwater levels and streamflow in many parts of the state. The total area of the state classified as experiencing drought or dryness decreased from over 70 percent at the beginning of the month to 55 percent this week. In contrast, south central Iowa is still experiencing D2 and D3 drought conditions. Clarke county and Wapello county are seeing the most extreme dryness.
Researchers point out that August temperatures this year have been about three to four degrees cooler than normal, on average. Lower temperatures slow down evaporation rates and provide a protective factor for crops in drought-stricken areas.
