An evaluation of temperature prediction models on Coastal Oregon and western Cascade streams

Creator:: Tanner, Robert W.
Abstract:: Evaluations were performed on three stream temperature prediction models: Heat Source 5.6, SSTEMP 3.9, and Brown's equation. Each model was evaluated using data collected from three Coastal Oregon and two western Cascade streams. Stream temperature simulations were performed on two forested reaches, one clearcut reach, and one buffered reach, for...

Sediment potentials for selected ecological land units in central Oregon

Creator:: Mattison, Jeffrey L.
Abstract:: During the summers of 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of Crook County, in central Oregon. The Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a...

Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Hydraulic influences on pool morphology : a laboratory investigation

Creator:: Frizenschaf, Jacqueline
Abstract:: A flume study was conducted to investigate the influences of changing hydraulic conditions on the bed morphology of a scoured pool. During a simulated storm runoff event, responses of the pool were tested under different conditions: clearwater flow, sediment supply at steady rates, and two different sediment mixtures of the...

Landslide occurrence in the Elk and Sixes River basins, southwest Oregon

Creator:: McHugh, Margaret H.
Abstract:: Timber management of coastal watersheds in southwest Oregon has been complicated by the need to protect anadromous fish habitat from accelerated stream sedimentation resulting from management activity. The rugged terrain of the Elk and Sixes River basins is underlain by the complex geological province of the Klamath Mountains, in which...

Seasonal changes in distribution and abundance of salmonids and habitat availability in a coastal Oregon basin

Creator:: Sleeper, Jack David
Abstract:: Visual estimation techniques were used to quantify habitat characteristics, habitat type (pool, riffle) use and longitudinal distribution of steelhead (Oncorhynchus mykiss), cutthroat trout (0. clarki), and coho salmon (0. kisutch) in spring, summer and fall in 8.8 km of Cummins Creek, a basin in the central coast of Oregon. Fish...

Distribution and characteristics of an isolated population of coastal cutthroat trout (Oncorhynchus clarki) in streams of Triangle Lake Basin, Oregon

Creator:: Hurley, Steven M.
Abstract:: This research focused on features of a genetically isolated population of cutthroat trout (Oncorhynchus clarki) in the Triangle Lake basin of coastal Oregon. A falls at the outlet of Triangle Lake has blocked upstream migration of trout and anadromous salmonids into the basin. Cutthroat trout were found throughout the six...

Incipient motion and particle transport in gravel-bed streams

Creator:: Matin, Habib
Abstract:: The incipient motion of sediment particles in gravel-bed rivers is a very important process. It represents the difference between bed stability and bed mobility. A field study was conducted in Oak Creek, Oregon to investigate incipient motion of individual particles in gravel-bed streams. Investigation was also made of the incipient...

Response of juvenile steelhead trout to an instream habitat rehabilitation project in Meadow Creek, Oregon

Creator:: Miller, Alan Christopher
Abstract:: Responses of juvenile steelhead trout to changes in stream habitat resulting from an instream habitat rehabilitation project in Meadow Creek, Oregon were measured from 1991 through 1992 and compared to pre-treatment data from 1987 through 1990. Sixty nine pool-forming, and 59 channel-stabilizing log structures were constructed by the U.S. Forest...

Pool habitat characteristics and juvenile anadromous salmonids in two Oregon coastal streams

Creator:: Haapala, Deborah L.
Abstract:: Relations between the diversity of juvenile anadromous salmonids and pool features were examined in a managed and a pristine watershed in Oregon during the summer of 1990. There were no differences (p>0.05) in pool depth, velocity or pool wood volumes between streams. However, the pristine system had twice the number...
