Last year was the second dry year in a row for the state, according to the Iowa Department of Natural Resources. Parts of central and west central Iowa recorded nearly a foot less moisture than normal over the past 24 months with streamflow and groundwater conditions a major concern during that period. However, an October with above-average precipitation helped the state end 2021 with near-normal levels. DNR Hydrology Coordinator, Tim Hall, says, “Looking back on 2021, the wet October we experienced in Iowa really helped set us up for better spring conditions. We would have much more concern for spring 2022 conditions without those October rains. Dryness could still be an issue as we move from winter to spring of 2022, and the DNR and our partners continue to watch conditions closely.” Last year began with drought conditions, particularly in northwest Iowa, and continued until they peaked in August. However, only about 12 percent of the state ended December with moderate drought conditions. Statewide average accumulation was just over 31 inches, about 4.5 inches below normal. Eight months of the year saw below-normal precipitation, which was significantly lower during late spring and early summer. Temperatures averaged 50 degrees Fahrenheit throughout the year, which is 1.6 degrees above normal. The DNR’s full 2021 report can be found included below.
