The effects of channel modification on characteristics of streams during low flow

Creator:: Atkinson, Brett
Abstract:: Fluorescent dye was used to assess summer low flow hydraulic retention and transient storage (dead zone) associated with fish habitat structures at Camp Creek, Drift Creek, and the East Fork of Lobster Creek within the central Coast Range of Oregon. Utilizing channel units to stratify stream reaches, the effect of...

Performance of perennial ryegrass (Lolium perenne L.) seed crops under water stress conditions

Creator:: Velloza, Theodosius Marmaduke
Abstract:: Summer drought is a major factor limiting the regrowth of perennial ryegrass seed crops. This phase of crop development has a strong influence on seed yield because most of the tillers that contribute towards next season's seed crop are produced or regrown during this period. In recent years many seed...

Bacteria die-off in stream sediments

Creator:: Sherer, Brett Micheal
Abstract:: The purpose of this study was to evaluate the impact sediment has on the survival of bacteria in a typical rangeland stream. This information is an important component in determining a time integrated prediction of bacterial numbers in the stream sediment and overlying water. Bacterial survival in stream is a...

Using valuation functions to estimate changes in the quality of a recreational experience : elk hunting in Oregon

Creator:: Fried, Brett M.
Abstract:: Public agencies need information on the value of recreational activities to assist in managing fish and wildlife species. Over the past two decades economists have developed and applied techniques to measure the value of such non-marketed commodities. The contingent valuation method (CVM) is one technique used by economists to measure...

Inventory of spawning habitat used by Oregon coastal fall Chinook salmon

Creator:: Hodgson, Brett L. and Jacobs, Steven E.
Abstract:: This study was performed in response to doubts about the reliability of the database in place at ODFW. It consisted of surveys to verify if Chinook salmon were using the habitats previously identified and looks for discrepancies between summer habitat inventory and fall Chinook spawners. A large portion of the...

Introduction to the OSU Extension Soil Sensitivity Database

Creator:: Huddleston, J. H. (James Herbert), 1942-, Mendez, W. R., Brett, M., Kerle, Elizabeth A., Vogue, Peggy A., and Oregon State University. Extension Service
Abstract:: The OSU Extension Soil Sensitivity Database lists nonirrigated and irrigated soil sensitivity ratings for every map unit of every soil survey in Oregon. These ratings were developed for the Oregon Water Quality Decision Aid, a tool for evaluating groundwater vulnerability to pesticide contamination.

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...
