| Abstract: | Par Pond and L Lake are reservoirs on the Savannah River Site in South Carolina. Beds of aquatic macrophytes (primarily cattail and waterlilies) exist in Par Pond and are now beginning to develop in L Lake. Biophysical knowledge about Par Pond was used to develop environmental constraint criteria' to predict the future spatial distribution of aquatic macrophytes in L Lake. The L Lake biophysical data were placed in a 5 × 5 m raster geographic information system (GIS) and analyzed using Boolean logic. Areas in L Lake which were ≤4 m in depth, ≤10% slope, had a fetch of ≤500 m, and on suitable soil were identified. The final GIS model predicted the spatial distribution of 37.30 ha of aquatic macrophytes which met the environmental constraint criteria (cattails = 12.29 ha and waterlilies = 25.01 ha) |
