Late winter 1992 sampling for water quality in three stream segments of the Tualatin River Basin, Oregon

Creator:: Miner, J. Ronald, Nelson, Peter O., Vedanayagam, Samuel, Oregon State University. Water Resources Research Institute, and Oregon State University. Extension Service
Abstract:: The Tualatin River Basin in Washington County, Oregon has been identified by the Oregon Department of Environmental Quality (DEQ) as "Water Quality Limited." Algal blooms have become commonplace in the lower , reaches of. the river during summer months. Phosphorus has been identified as the nutrient upon which to base...

A statistical evaluation of the water quality impacts of Best Management Practices installed at Tillamook County dairies

Creator:: Dorsey-Kramer, Jadene
Abstract:: The overall goal of this study was to determine if the Tillamook Bay tributaries' water quality has improved as a result of the Best Management Practices (BMP) installed at Tillamook County Dairies. The Rural Clean Water Program (RCWP) was a 10 to 15 year experiment designed to control agricultural non-point...

Source identification of fecal pollution in the Tillamook watershed : antibiotic discriminant analysis

Creator:: Bower, Robert J.
Abstract:: The identification of sources of point and nonpoint fecal pollution is difficult to determine. Understanding the sources of fecal organisms in quality limited waters could greatly enhance our ability to restore and protect the water quality and habitat of these systems. Antibiotic resistance patterns of fecal streptococci bacteria were analyzed...

Fecal coliform bacteria in stream sediments : sampling methodology, measurement and modeling the impact on stream water quality

Creator:: Church, Wendy S.
Abstract:: Three studies were conducted related to the measurement and impact of stream sediment fecal coliform (FC) bacteria on stream water quality. In part one an enumeration technique for sediment FC was defined and statistically characterized. This characterization necessitated the development of a sample splitting mechanism, which was found to split...

Data analysis: water quality of Dairy Creek and major tributaries

Creator:: Oregon State University. Water Resources Research Institute, Miner, J. Ronald, and Scott, Eric F.
Abstract:: Dairy Creek, located in Washington County, Oregon, has a drainage area of approximately 230 square miles, and includes West Fork, East Fork, and McKay Creek drainages. Dairy Creek is a major tributary of the Tualatin River which experiences algal problems during the late summer when stream flows decrease and water...

Estimating the frequency and quantity of surface runoff within the Tualatin River Basin

Creator:: Taylor, George H., Klingeman, Peter C., Miner, J. Ronald, and Oregon State University. Water Resources Research Institute
Abstract:: The Tualatin River Basin along the east side of the Coastal Mountains in Oregon is subject to a complex mixture of land uses. Approximately half the area is devoted to forestry production. The remainder is divided between agriculture and urban uses. In addition to this diversity in land use, there...

Agricultural land use in the Tualatin Basin

Creator:: Scott, Eric F., Wood, Mary, Warkentin, Benno P., and Oregon State University. Water Resources Research Institute
Abstract:: This report presents estimates of land uses, concentrating on agricultural land in the Tualatin drainage basin. Acreage in different crop groups and agricultural water use and distribution in the watershed were estimated. The total amounts of nitrogen and phosphate applied to agricultural land and the average loading of nutrients per...

An analysis of water quality data in Tualatin River tributaries with three different land uses

Creator:: Miner, J. Ronald, Scott, Eric F., and Oregon State University. Water Resources Research Institute
Abstract:: Water quality and stream flow data for tliree representative land uses in the Tualatin River Basin were evaluated to determine the comparative levels of various pollutants. In addition, the data were used in an effort to identify the extent to which observed concentrations of total and ortho phosphorus could be...
