Description: Recent studies conducted in conjunction with the International Joint Commission Reference on Pollution from Land Use Activities (Knap and Mildner 1977 Knap 1978) have revealed that erosion from streambanks and drainage ditches contributes in the order of 600 000 tonnes of suspended sediment annually to the Great Lakes. This volume constitutes about 12.5% of the total suspended load derived from river inputs to the lakes. Although the amount of streambank erosion in the Great Lakes Basin may be considered from a lake perspective to be relatively small, the localized effects of this type of erosion are not necessarily insignificant. For example, an investigation of 16 small agricultural watersheds in Southern Ontario has revealed that 45% of the total bank area of streambanks and drainage-ways exhibits some type(s) of erosion (the figure has been computed to be up to 70% in some basins) and 15% of the bank area is completely exposed (up to 50% in selected watersheds) (Dickinson and Winch 1977). Further, Knap (1978) suggests that in the Canadian portion of the Great Lakes Basin as much as 30% or more of the annual suspended sediment load leaving various agricultural watersheds can be contributed by the banks of upland watercourses.
