Pilot Freshwater Mussel Survey in King County Results of a pilot freshwater mussel survey in Bear Creek, Stossel Creek, and Covington Creek, King County, Washington State. Puget Sound Stream Benthos: Monitoring Status and Data Management Sammamish River Corridor Action Plan The plan focuses on the Sammamish River's role as a necessary migratory corridor for anadromous salmon in the Sammamish Watershed. Implementation of the plan, however, would benefit more than just salmon and a wide range of other wildlife; it would also enhance the river corridor's ability to serve as a place of pleasure and refuge for the surrounding human community. Sammamish River Diel pH and Dissolved Oxygen Study The Sammamish River has recently been the focus of a number of water quality studies, primarily due to the use of the river by Endangered Species Act (ESA) listed species of salmon. A review of Sammamish River monitoring data has also led the Washington State Department of Ecology to identify water quality problems related to elevated levels of fecal coliform bacteria, temperature, and pH and reduced levels of dissolved oxygen in the river (Washington State Department of Ecology 2000 303(d) list of impaired waters). Sammamish River Water and Sediment Quality Assessment The objectives of the project were to provide an assessment of the current water and sediment quality conditions in the river, and to begin a database of analytical results for Sammamish River that would be useful for multiple King County projects (e.g., ESA-listed salmon, water reuse). Sediment Quality Evaluation in Lake Sammamish, Lake Union, and Lake Washingon The Sediment Quality Triad (SQT) approach to sediment quality evaluation was used to characterize and assess the extent of altered benthic invertebrate assemblages, sediment contamination and toxicity in Lakes Sammamish, Washington, and Union near Seattle, Washington.
