  Citation × Citation Citation Abstract Copy Title: Selected elements and organic chemicals in bed sediment and fish tissue of the Tualatin River Basin, Oregon, 1992-96 Author: Bonn, Bernadine A., Washington County (Or.). Unified Sewerage Agency., Geological Survey (U.S.) The U.S. Geological Survey (USGS) has worked cooperative with the Unified Sewerage Agency of Washington County (USA) since 1990 to assess water quality in the Tualatin River Basin. The objectives of this study were to: assess the occurrence and magnitude of trace element and selected organic contaminants in streams of the Tualatin River Basin; compare contaminant levels found in Tualatin River Basin streams with published guidelines for the protection of aquatic life; place the contaminant levels found in the Tualatin River Basin streams in context, regionally and nationally, by comparing them with those found in the Willamette Basin and by the USGS National Water-Quality Assessment (NAWQA) Program; compare contaminant concentrations in bed sediment with those in fish tissue; and identify contaminant patterns that would help managers make decisions regarding future monitoring and the implementation of pollution prevention and abatement programs.

Water Resources Dept., Miller, Suzanne J., Friday, John, Geological Survey (U.S.) Statistical summaries of streamfiow data at 123 stream-gaging sites are presented in this report to aid in appraising the hydrology of river basins in Eastern Oregon. Records for 13 gaging stations were compiled into separate periods owing to changes in regulation during the period of data collection. The periods before and after regulation are presented for comparison. A brief station description is given describing the physical and operational features for each gaging station. Following the station description are tables of monthly and annual flow statistics, flood frequency data, low-flow and high-flow frequency data, and flow-duration information.
