Technical Abstract: Water use during the dormant season is often considered to be insignificant in terms of the total water balance. Evapotranspiration was measured over three fields with different crop covers during the winter of 1994-95 in central Iowa using a Bowen ratio system. Daily evapotranspiration ranged from less than 1 mm/day to over 3 mm/day, and the evaporative fraction ranged from 40 to 90%. Evapotranspiration was a significant factor during the winter in Iowa.
