DescriptionThe goal of the debris survey was to identify buried objects that may be hazards to the dredging operation in the proposed pilot study area. Both sub-bottom and magnetometer surveys were conducted in an attempt to identify objects buried beneath the surface of the sediment. The survey work encompassed the entire river bottom, to the MLW mark along each shoreline. The survey extended for 1000 feet along the river centerline from bank to bank. None of the targets located were found to have signatures indicative of historically significant submerged cultural resources. Because all of the materials generating the targets are buried below the surface of the sediment, it is impossible to positively identify them using remote sensing equipment. Whether the targets identified are a concern for the future dredging operations cannot be determined. Should the potential exist for the dredging equipment to be damaged by the targets, further investigation may be necessary to determine the nature and depth of burial of the material generating the anomaly.
