Statistical summaries of streamflow data at 212 stream-gaging sites
are presented in this report to aid in appraising the hydrology of river
basins in Western Oregon. Records for 21 gaging stations were compiled
into separate periods owing to changes in regulation during the period
of data collection. The periods before...

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...
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...
