The short term temporal and spatial variability of nitrogen and phosphorus in two Oregon Coast Range streams

Creator:: Scherer, Robert A.
Abstract:: High intensity sampling was undertaken to characterize the temporal and spatial variability of oxidized nitrogen (NO3-N + NO2-N), ammonia-nitrogen (NH3-N), total dissolved phosphorus, total unfiltered phosphorus and orthophosphorus (PO4-P) from two adjacent small streams in Western Oregon's Coast Range, Deer Creek (303 ha) and Flynn Creek (203 ha). Deer Creek...

Summer stream temperatures and channel characteristics of a southwestern Oregon coastal stream

Creator:: McSwain, Michelle D.
Abstract:: The Elk River Basin drains 93 sq ml of steep forested terrain on the west side of the Klamath Mountains in Southwest Oregon. This river and its tributaries support a diverse and abundant population of anadromous fish; a hatchery located at river mile 13 (km 21) supplements these native populations....

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...

Controlling water temperatures with buffer strips

Creator:: Brazier, Jon Roger
Abstract:: Buffer strips have been proposed as a method for controlling temperature changes in streams adjacent to clear-cuttings. Nine small mountain streams in Oregon's Coast Range and Cascade Mountains were studied to determine the influence of buffer strips on water temperature. Timber volume in the strip, strip width, and canopy density...

Summertime stream temperatures in the North and South Forks of the Sprague River, south central Oregon

Creator:: Friedrichsen, Paul T.
Abstract:: The Upper Sprague River Watershed (North and South Forks of the Sprague River) in south central Oregon provides important habitat for salmonid species, including native bull trout (Salvelinus confluentus) and redband trout (Oncorhynchus mykiss ssp.). Concern over the loss of viable habitat for these species has increased due to reductions...

A physical and chemical characterization of stream water draining three Oregon Coast Range catchments

Creator:: Hale, V. Cody
Abstract:: Few studies have examined both long-term and fine-scale spatial variations in water quality of small streams in the Pacific Northwest. As such, a case study was conducted to determine if current physical and chemical properties of water in three streams located in the Oregon Coast Range differed from historically measured...

Groundwater elevations and temperature adjacent to a beaver pond in central Oregon

Creator:: Lowry, Michael M.
Abstract:: This study was designed and implemented to observe the spatial and temporal dynamics of groundwater levels and temperatures adjacent to a beaver pond in semi-arid central Oregon. The study site was located on the eastern boundary of Painted Hills National Monument along Bridge Creek, a tributary to the John Day...
Resource Type:: Masters Thesis

The influence of contemporary forest management on stream nutrient concentrations in an industrialized forest in the Oregon Cascades

Creator:: Meininger, William Scott
Abstract:: The increased demand for wood and fiber from a continually shrinking land base has resulted in the use of intensively managed forest plantations. The concentration of timber production on the most suitable sites allows the world's demand for forest products to be met on less land and enable native forests...

The influence of contemporary forest harvesting on summer stream temperatures in headwater streams of Hinkle Creek, Oregon

Creator:: Kibler, Kelly Maren
Abstract:: Stream temperature is a water quality parameter that directly influences the quality of aquatic habitat, particularly for cold-water species such as Pacific salmonids. Forest harvesting adjacent to a stream can increase the amount of solar radiation the stream receives, which can elevate stream temperatures and impair aquatic habitat. Oregon Forest...

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...
