An eleven year study of nitrate leaching in vegetable production with winter cover crops

Creator:: Feaga, Jeff
Abstract:: The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...

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...

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...

The development and analysis of future agricultural landscapes

Creator:: Berger, Patricia A.
Abstract:: Alternative futures studies provide a way for policy-makers and stakeholders to investigate the future impacts of different management strategies by providing representations of possible outcomes. An alternative futures study was undertaken by the Pacific Northwest-Ecosystem Research Consortium for the Willamette River Basin, Oregon, USA, to determine how this regional system...

Implementing best management practices in small commercial and non-commercial animal enterprises

Creator:: Godwin, Derek C.
Abstract:: Small commercial and non-commercial animal enterprises (SCAEs) raise a few beef cows, horses, pigs, sheep, poultry, and other animals on a few acres. These enterprises are often located in suburban areas of watersheds and show potential for degrading water quality through to increased bacterial, nitrogen, and phosphorus concentrations. SCAEs implement...

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...

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...

A spatially explicit method for determining the effects of watershed scale land use on stream conditions

Creator:: Kehmeier, Jonathan W.
Abstract:: The primary goal of this research was to identify the impacts that individual agricultural land uses have on fish communities in small streams located in the Willamette Valley of western Oregon. The diverse nature of the land use features of the valley provided a challenging but useful system for the...
