A morphometric study was made of the adjoining drainage basins of east-flowing Old Man Creek and Clear Creek in Johnson and Iowa counties, Iowa. In terms of the parameters measured, these basins are essentially similar. They agree with "laws" for drainage basins proposed by Horton and are therefore "normal" rather than "misfit". Part of the Clear Creek basin was invaded by Iowan ice and this probably accounts for some abnormal data. Distinct longitudinal asymmetry and obviously steeper south valley walls are probably best explained by the differences in loess thickness on valley sides.
