Description: We assessed the effect of beaver dams on channel gradation of an incised stream in an agricultural area of eastern Nebraska. A topographic survey was conducted of a reach of Little Muddy Creek where beaver are known to have been building dams for twelve years. Results indicating that over this time period the thalweg elevation has aggraded an average of 0.65 m by trapping 1730 t of sediment in the pools behind dams. Beaver may provide a feasible solution to channel degradation problems in this region.

Keywords: beaver dams, channel aggradation, sediment, agricultural watershed
