The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

Vegetation and soil response to tree removal methods in invasive western juniper woodlands

Creator:: O'Connor, Casey A.
Abstract:: On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...

Post-accident radiocesium uptake in eastern Oregon wheat crops : A preliminary estimate using a modified "PATHWAY" model

Creator:: Palotay, Joshua A.
Abstract:: An experimental environmental uptake model was developed for the purpose of estimating the final harvest concentration of contaminant following an acute accidental release of radiocesium onto an eastern Oregon winter wheat crop. The system was developed using the PATHWAY environmental uptake model as presented by Whicker and Kirchner (1987) for...

Economics of drought preparedness and response in irrigated agriculture

Creator:: Peck, Dannele E.
Abstract:: The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...

Municipal water source turbidities following timber harvest and road construction in western Oregon

Creator:: Grizzel, Jeffrey D.
Abstract:: Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...

After the rain: urban runoff

Creator:: Oregon State University. Extension Service and Dodrill, Steve.
Abstract:: This program explains that urban water pollution comes from a number of common sources, such as automobiles, lawn and garden fertilizer, and pet waste, and explores ways in which citizens can minimize their contribution to such pollution.

Analysis of the Oregon Stakeholder Drug Take Back Public Policy Process to ReducePharmaceutical Pollution in Oregon’s Water Resources

Creator:: Hubbard, Monica L.
Abstract:: The goal of this analysis is to use the social construction framework to determine 1) whether the Oregon Drug Take Back Program stakeholder group can design a public policy that will ultimately reduce water contamination from the improper disposal of unused pharmaceuticals from the general public, and 2) use the...

An Ecoregion-Based Reference Condition and Classification Scheme for Determining Nutrient Criteria in Oregon Lakes

Creator:: Brenner, Jacqueline M.
Abstract:: The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...
