Water quality of runoff from flood irrigated pasture in the Klamath Basin, Oregon

Creator:: Ciotti, Damion C.
Abstract:: Runoff from agricultural lands into Upper Klamath Basin rivers and lakes can cause water quality problems affecting fish and wildlife. Excessive eutrophication in Upper Klamath Lake is linked to high nutrient input (particularly phosphorus) stemming from both lake sediments and watershed tributaries. On a unit area load basis the Wood...

Investigation of the presence and change over time of water quality parameters in selected natural swimming areas in Oregon

Creator:: Van Ess, Erica
Abstract:: Few studies, and none in Oregon, have examined the presence and change of water quality parameters over time in popular natural swimming areas. This information is necessary to better understand water quality and risk of illness from either fecal contamination or cross-infection from other swimmers. The purpose of this study...

The effects of red alder leaf fall on the water color and other water quality characteristics of a small watershed in northwest Oregon

Creator:: Taylor, Robert Lynn
Abstract:: This study was initiated to make some preliminary evaluations of the effects of red alder (Alnus rubra, Bong.) leaf fall on stream water quality, particularly water color. Laboratory tests were also conducted to better understand the effects of leaf loading, duration of leaf leaching, and type of leaching on changes...

Investigation of the hydraulic, physical, and chemical buffering capacity of Missoula Flood Deposits for water quality and supply in the Willamette Valley of Oregon

Creator:: Iverson, Justin
Abstract:: The Willamette Silt is a surficial geologic unit composed of successive Missoula Flood Deposits that underlies 3100 km2 (1200 mil) of arable land in the Willamette Valley of Oregon. The Willamette Silt protects the underlying regionally important Willamette Aquifer from agricultural contamination while acting as a semi-confining unit and a...

The spatial and temporal variability of nitrate in streams of the Bull Run Watershed, Oregon

Creator:: Bakke, Paul D.
Abstract:: An 18-year record of nitrate (NO₃), orthophosphate, total nitrogen and total phosphorus in four streams of the Bull Run watershed, Oregon, was examined to determine its precision and time resolution. Of these four species, only NO₃ was found to be known to a sufficient level of detail for modeling and...

Stream DOC, nitrate, chloride and SUVA response to land use during winter baseflow conditions in sub-basins of the Willamette River Basin, OR

Creator:: Frentress, Jay
Abstract:: To better understand the impact of land use on stream nutrient export, a synoptic sampling of 57 sub-basins within the Willamette River basin was conducted during winter baseflow conditions (February 2009). I assessed whether stream dissolved organic carbon (DOC), NO₃⁻ and Cl⁻ and specific ultra-violet absorbance (SUVA) values were correlated...

An analysis of well water quality and local residents' perceptions of drinking water quality in the southern Willamette Valley

Creator:: Kite-Powell, Aaron C.
Abstract:: The purpose of this study was to; (1) determine the extent of well water contamination with nitrate and pesticides, and to understand the relationships among nitrate, pesticide, dissolved chloride, dissolved sulfate, well age, and well depth in the southern Willamette Valley, Oregon; and, (2) to investigate local residents' perceptions and...

Chemical and isotopic patterns of nitrate variability in the southern Willamette Valley, Oregon

Creator:: Vick, Christopher Flanders
Abstract:: A relatively stable, persistent and historical problem with elevated NO₃⁻ concentrations in rural drinking wells in the southern Willamette Valley, Oregon is evident. What is the origin of NO₃⁻ in rural drinking water wells in this area? The answer to the question is not simple. Many non-point sources contribute to...
