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...

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.

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...

Resource Type:: Undergraduate Thesis

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...

Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

Creator:: Heimann, David C.
Abstract:: This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...

Response to Water Protection Rule changes in the Oregon Forest Practices Act : landowner/operator opinions and streamside conditions

Creator:: Hairston, Anne B.
Abstract:: This study assessed implementation of the 1994 Water Protection Rules in the Oregon Forest Practices Act from the perspective of Rule users and post-harvest riparian conditions. A 1993 evaluation found that under the previous rules over half of riparian conifers were removed during harvest, prompting concerns about future sources of...
