Report of dam at Chitwood mill on Haxel Creek, a tributary of Thornton Creek

Creator:: Waldron, Kenneth D. and Oregon Fish Commission. Shellfish Program
Abstract:: Describes an investigation of a dam at a millpond near the village of Chitwood, Oregon. The dam was on Haxel Creek, a tributary of Thornton Creek, a tributary of the Yaquina River. Includes a hand-drawn map of the area.
Resource Type:: Technical Report
Full Text:: to 10 years. The owner of the mill, Chet Minnie of Corvallis, Oregon, was not available for an inter

Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:: Skaugset, Arne E.
Abstract:: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...

The geomorphic significance of log steps in forest streams of the Oregon Coast Range

Creator:: Marston, Richard A.
Abstract:: A log step develops when large woody debris extends across the active channel, creating a change in the water surface elevation as the stream spills over the log step. By forming a series of vertical falls, log steps reduce the amount of potential energy available for conversion to kinetic energy...

Forest harvesting impacts on coarse woody debris and channel form in central Oregon streams

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

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...

Alsea watershed study : to determine the effects of logging on aquatic resources

Creator:: Hall, James D.
Abstract:: This report describes the preliminary results of a study to compare effects of clear-cut and staggered logging on fish and other aquatic resources in small headwater streams. The results of this study were published in ODFW Fishery Research Report 9 in 3 parts.

Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

Soil compaction from low ground-pressure, torsion-suspension logging vehicles on three forest soils

Creator:: Froehlich, Henry A. and Oregon State University. Forest Research Laboratory
Abstract:: Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...
