Historical climate data for the Midwestern U.S. show substantial regional variability in the occurrence of extreme rainfall events.  Climate projections for the region based on both statistically downscaled General Circulation Models and Regional Climate Models show significant inter-model variability in the magnitude and frequency of extreme rainfall events.  As a result, these climate projections cannot be used alone to adaptively manage water resources in a changing climate.  We believe that storm transposition provides an effective way to evaluate the vulnerability from extreme rainfall and flooding. We have reconstructed the 2008 storm that caused catastrophic damage across parts of south-central Iowa and Wisconsin.  We are currently using an existing hydrodynamic model of the Yahara Lakes ( to estimate the extent of damage that would have occurred had the storm been centered over the lakes
