Habitat Development Field Investigations, Miller Sands Marsh and Upland Habitat Development Site, Columbia River, Oregon. Appendix B. Inventory and Assessment of Predisposal and Postdisposal Aquatic Habitats.
Abstract
Miller Sands, an island-lagoon complex located in the Columbia River Estuary at River Kilometre 39 (River Mile 24) was one of five research projects where the feasibility of using dredged material for beneficial habitat development was studied. The study was conducted during predisposal, disposal, and postdisposal phases from March 1975 to July 1977. The National Marine Fisheries Service was part of a five-agency team charged with the investigation of various physical, chemical, and biological parameters during the marsh development program. The National Marine Fisheries Service research findings describe changes in sediments, macroinvertebrates, various water quality parameters, zooplankton, nekton, and nekton food utilization. Water flow conditions in the Columbia River were high in 1975, average in 1976, and were exceedingly low during the winter of 1976 and the spring-summer of 1977. Water quality parameters that were manifested as a result of these changes in flow probably overpowered subtle changes that could have developed as a result of the habitat improvement project at Miller Sands. Water quality parameters monitored were water temperature, pH, salinity, dissolved oxygen, turbidity, ammonia, total alkalinity, and nitrogen gas.
