Abstract:

The LummiSinclair Island ZSFZone of Siting Feasibility and the McNeil Island ZSF in south Puget Sound were found to be unsuitable as nondispersive sites for the disposal of dredged material. At both ZSFs the grain size of the sediment was much too coarse and little organic material was in evidence. In addition the macrofaunal communities at both ZSFs were characteristic of a suspension feeding community which indicate that water currents in the ZSF are relatively high. 2 Areas were located within each of the remaining 3 ZSFs that are suitable nondispersive sites. 3 In Bellingham bay the area that appears to be the most depositional is locate roughly 0.5 nautical miles north of the existing ZSF. 4 The area of greatest deposition within the AndersonKetron Island ZSF is located in the center area being slightly more depositional. 5The region at the entrance to Drayton Passage has the greatest potential to be depositional. Concentrations of all measured parameters exceed the 95 CI and 1.96 SND in this region.
