Studies were initiated to inventory and classify the training structures along the Iowa bank of the Upper Mississippi River Pools 9 through 19. A total of 595 wing and closing dams were inventoried. Physical data collected from each dam site included water depth and river bottom contour, current velocities, and substrate samples. Data indicated that 217 (36 percent) of the dams within the study area had been completely eroded, covered with bottom sediments, or were physically removed by the Corps of Engineers. The remaining dams were sorted into twelve definable groups based on their physical characteristics, hydraulic regime and effect of the structure on the surrounding area.
