Watershed Assessment Of Tryon Creek Of Oregon, Danielle Goodrich
Watershed Assessment Of Tryon Creek Of Oregon, Danielle Goodrich
Environmental Science and Management Professional Master's Project Reports
As the Tryon Creek Watershed Council (TCWC) continues to grow its organization, it is important to focus their efforts on lasting changes that most positively affect the watershed. The TCWC plays a community-appointed role as the binding element of agency and stakeholder partnerships throughout the Tryon Creek watershed by providing communication and cooperation. The watershed assessment aims to provide a compilation of existing data as well as an identification of data gaps and recommendations for future cooperative management of the watershed. Developing an understanding of the processes that shape the watershed can shed light on the status of measurable ecosystem …
Process-Based Modeling Of The Dairy Mckay Watershed To Inform Monitoring For Agricultural Best Management Practices, Brittany Saeman
Process-Based Modeling Of The Dairy Mckay Watershed To Inform Monitoring For Agricultural Best Management Practices, Brittany Saeman
Environmental Science and Management Professional Master's Project Reports
The project described in this paper specifically looks at the influence of land management practices on water quality, specifically total phosphorus (TP) loads in the Dairy McKay Watershed (DMW). The project is being used to inform a water quality monitoring plan for the Oregon DEQ via outputs from a SWAT model. The DMW is known to have high TP levels that are linked to low dissolved oxygen levels in the Tualatin River. There is a total maximum daily load (TMDL) for the Tualatin River that specifies target TP levels coming out of the DMW, if these targets are met, the …
Analysis Of Toxic Pollutant Sources And Characteristics Contributing To Water Quality Impairments In The Willamette River Basin, Melinda Borgens
Analysis Of Toxic Pollutant Sources And Characteristics Contributing To Water Quality Impairments In The Willamette River Basin, Melinda Borgens
Environmental Science and Management Professional Master's Project Reports
Point and nonpoint sources contribute toxic pollutants to surface waters, degrading water quality and impairing aquatic and human life. As of 2012, 51 stream segments totaling approximately 6,000 kilometers (3,750 miles) in Oregon’s Willamette River Basin (the Basin) were listed as impaired on the Clean Water Act's (CWA) Section 303(d) list with 48 toxic pollutants. These toxic pollutants exceed the Oregon Department of Environmental Quality's (DEQ) state water quality standards, requiring Total Maximum Daily Loads (TMDLs) to restore water quality and protect beneficial uses. Identifying toxic pollutant point and nonpoint sources, and the total loads a waterbody receives, are critical …
