This report evaluates the potential environmental impact of proposed maintenance dredging at Oak Orchard Harbor, New York, by the U.S. Army Corps of Engineers. Field samples were obtained in autumn 1978 and spring and summer 1979. Data reports based on these sampling efforts were submitted earlier to the Buffalo District of the U.S. Army Corps of Engineers.

The impact of dredging was considered in relation to physical and chemical conditions, terrestrial vegetation/wetlands, aquatic macrophytes, macrobenthos, phytoplankton and zooplankton, fish, birds, endangered species, toxic chemicals and seiches.

For each factor considered, sections entitled Existing Conditions are followed by our Assessment of Impact. The last section presents our conclusions and recommendations concerning the general impact of dredging.
