Analyses of total soil water monitored over a 7‐yr period on reshaped, vegetated spoil and nearby undisturbed grassland sites indicate that little, if any, water percolated beyond the rooting zone (0–122 cm) at either the spoil or undisturbed grassland sites. Total soil water below the rooting zone decreased over time, presumably due to upward movement by unsaturated flow in response to gradients created in the rooting zone by evapotranspiration. The spoil sites contained more total soil water in 1974 than the undisturbed sites but greater evapotranspiration losses at the spoil sites had presumably decreased soil water to a level nearly equal to that of the undisturbed sites by 1981.
