"This document presents the most detailed calculation of areal coverages for sedimentarysubstrates in Lake Erie. Some of these substrates have importance as fish habitats. Furthermore, when combined with spot sample counts, their coverage is critical in estimating ZM total numbers. ZM presently cover most of the 46% of the western basin composed of coarse glacial sediments (till and lag gravels), clean sand and gravel, and exposed bedrock. The dominant substrate, mud (54%) is also being colonized in some areas. A review of sediment inputs to the lake indicates that shore erosion, bringing in relatively clean, glaciogenic sediments might be acting to dilute the more severely contaminated tributary inputs of sediment"--Management perspective. gccst Inland waters gccst Sediments Pippert, Rolf G.
