Abstract:: Through the trapping of sediment behind dams, the presence of beaver in a watershed may cause substantial changes to fluvial and geomorphic processes. In an effort to investigate sedimentation patterns in beaver ponds in the Oregon Coast Range, a case study was made of the annual accumulation of sediment in...

Creator:: Edwards, Richard Earl
Abstract:: Sediment transport measurements on Flynn Creek, a headwater stream in the Oregon Coast Range, have illustrated the magnitude of fluvial transfer processes, primarily of the bedload component, during a moderate storm runoff season (1979 water year). The total dissolved solids concentration of storm runoff averaged 40 mg/L, and was independent...

Creator:: Poage, Nathan Jeremy
Abstract:: Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, timber, and aesthetics. A retrospective approach was taken in this study in order to understand and compare the structure, pattern, and history of an...

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...

Creator:: Bruner, Karen L.
Abstract:: The effects of beaver (Castor canadensis) on stream morphology, riparian zones, and coho salmon (Oncorhynchus kisutch) fry in Cape and Cummins Creeks, Oregon, were examined using stream surveys, vegetation transects, and coho salmon fry counts in 1987. The basin around Cape Creek has been extensively logged since the late 1940's....

Creator:: Talabere, Andrew G.
Abstract:: The distribution of Lahontan cutthroat trout Oncorhynchus clarki henshawi was assessed in a high-desert stream in southeastern Oregon where beaver Castor canadensis are abundant. Longitudinal patterns of beaver ponds, habitat, temperature, and Lahontan cutthroat trout age group distribution were identified throughout Willow Creek. Three distinct stream segments were classified based...

Creator:: Dent, Elizabeth F.
Abstract:: Esmond Creek is a tributary to the Siuslaw River located in the Oregon Coast Range. It is 18 km in length and drains a watershed area is 48.9 km². Average channel gradient of the study reach is 0.9%. In 1988 a landslide occurred in the Esmond Creek watershed involving approximately...
