Major pools of the Avon River have filled with sediment as a result of alteration to the river channel during the 1950-70s to reduce flood risk, and by soil erosion from agricultural catchments. Some pools are completely filled with sediments and their environmental and social values are lost. Others are filling rapidly. There is further potential for significant sediment transport to the pools and channels in the upper reaches of the Swan River.
