Reddy et al . (2006, Hydrological Processes 20 : 1753–1772) disregard germane published data and successful isotopic models, selectively depict data from their data sets, misplot many of their data, and use poorly correlated sinusoidal fits to their data to derive erroneous hydrologic time constants for features in the Shingobee River Headwaters Area. A damped running average model is more realistic. Copyright © 2006 John Wiley & Sons, Ltd.
