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.

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.

Forest Service, Geological Survey (U.S.) This report presents the concentrations of major ions, nutrients, and trace elements in water and bottom sediments collected in the four-tributaries during the low-flow condition of September 9-13, 1996. Stream-water chemistry results are contrasted, and trace-element concentrations compared with U.S. Environmental Protection Agency chronic aquatic life toxicity criteria. Bottom -sediment trace-element results also are constrasted and compared with concentrations considered to be enriched in streams of the nearby Willamette River Basin and to interim Canadian threshold effect level (TEL) concentrations established for the protection of aquatic life.
