Water Summary Update - 2013 in Review
Although precipitation for 2013 ended about normal, the first half of the year received about 7.4 inches of precipitation over normal and the second half of the year 7.7 inches under normal. Drought conditions improved dramatically during the course of the year, yet the middle portion of central Iowa remained in moderate drought by December’s end.
Shallow groundwater improved, but that was probably due to cooler temperatures rather than recharge, given the dry summer. The frost in the upper 48 inches of topsoil across the state has prevented groundwater recharge since November. However soil moisture reserves are better than a year ago.
