The purpose of this study was to evaluate the loss of soil and nutrients from the upland area of ten selected small watersheds or subwatersheds surrounding Conesus Lake. Macrophyte beds of mixed composition exist around the entire edge of Conesus Lake – perimeter beds. In addition, macrophyte beds consisting mainly of Eurasian milfoil exist at or near many of the creek mouths within the littoral zone of Conesus Lake. These creek-mouth associated beds are of interest because their presence may be associated with creeks that lose a large amount of nutrients and soils from their subwatershed
