Spatial and temporal variability in floodplain backwater sedimentation, Pool Ten, Upper Mississippi River

Description :
Sedimentation in Upper Mississippi River (UMR) aquatic habitats known as backwaters has been an issue of concern since the installation of navigation locks and dams in the late 1930s. Four cores were extracted from isolated backwaters in Navigation Pool Ten near Bagley, Wisconsin, in summer 2001. Particle size, organic carbon, and carbonate analyses were used to determine sedimentation response to changes in flooding associated with the dams. Potential changes in recurrence frequencies of large UMR floods and their driving forces should also be considered in evaluating the future of backwaters.
