Description In November 1988 the Washington State Department of Ecology began a Sediment Trap Monitoring Program in the Nearshore/Tideflats area of Commencement Bay. The program was aimed at evaluating the effectiveness of source control efforts designed to reduce the input of problem chemicals to Thea Foss Waterway. The primary component of this program consisted of a quarterly collection of settling particulate matter (SPM) with the use of moored sediment traps. In-place bottom sediments, current velocity measurements and water column profile data have also been collected periodically as part of the program. Based on the results from Thea Foss Waterway, sediment trap monitoring was expanded in July 1990 to include Hylebos and Sitcum Waterways.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
