Physical dimensions and hydrologic effects of beaver ponds on Kuiu Island in southeast Alaska

Creator:: Beedle, David L.
Abstract:: Dimensional characteristics of 44 beaver dams and ponds on Kuiu Island in Southeast Alaska were determined to evaluate the hydrologic effects of these structures on peak flows. The study area consisted of low gradient, incised streams in broad U-shaped valleys. Pond routing simulations were conducted using four return intervals (2-,...

Sediment transport and channel morphology in a small mountain stream in Western Oregon

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...

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...

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....

Influence of hillslope and instream processes on channel morphology of Esmond Creek in the Oregon Coast Range

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...

Hydrology and delineation in four wetlands in the Oregon Cascades

Creator:: MacLeod, Norman A.
Abstract:: Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

Coarse woody debris in streams of the Drift Creek Basin, Oregon

Creator:: Veldhuisen, Curt N.
Abstract:: This study examined the occurrence of coarse woody debris (i.e., pieces greater than 0.15 m in diameter and 2.0 m in length) in first- through fifth-order streams located within the Drift Creek Basin of the Oregon Coast Range. Nine "tributary reaches" were surveyed to determine how three land management treatments...

Infiltration capacities and surface erodibility associated with forest harvesting activities in the Oregon Cascades

Creator:: Johnson, Michael G.
Abstract:: An infiltration capacity and surface erodibility study was conducted six years after forest harvesting in the Oregon Cascades. A portable rainfall simulator was utilized to obtain field measurements on the Coyote Creek and Hi-15 Watersheds during summer and fall, 1977. Seasonal variations were found to occur in infiltration capacities and...

Summertime water temperature trends in Steamboat Creek Basin, Umpqua National Forest

Creator:: Holaday, Steven A.
Abstract:: The Steamboat Creek basin drains 227 mi² (588 km²) of steep forested terrain into the North Umpqua River of Southwest Oregon, 39 mi (63 km) northeast of Roseburg. Summer base flows for Steamboat Creek average 83 cfs (2.35 m³/sec). Steamboat Creek and its tributaries are considered important to the production...

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...
