An evaluation of the effectiveness of instream structures for steelhead trout rearing habitat in the Steamboat Creek basin.

Creator:: Fontaine, Barbara L.
Abstract:: Several types of instream structures were evaluated for their potential to provide rearing habitat and to increase reach carrying capacity for steelhead trout (Salmo gairdneri). Evaluation was conducted in each season over the course of 1 year. Blast pools created in bedrock glides increased the carrying capacity of stream reaches...

Prediction of peak flows for culvert design on small watersheds in Oregon

Creator:: Campbell, Alan J.
Abstract:: Forest engineers must frequently make flood frequency estimates for very small watersheds when designing culvert installations. Empirical formulae and simplified rainfall runoff models, the most commonly used techniques to predict floods from very small watersheds, require considerable engineering judgement to give reasonable results. As an alternative to such methods, this...

A bioeconomic analysis of altering instream flows anadromous fish production and competing demands for water in the John Day River basin, Oregon

Creator:: Johnson, Neal S.
Abstract:: The growing demand for water in the arid regions of the West increases the need for optimal allocation of water among competing uses. An efficient allocation of water between instream and out-of-stream uses has been impeded by institutional constraints and the scarcity of information regarding instream flow benefits. The objectives...

Sediment routing in a small watershed in the blast zone at Mount St. Helens, Washington

Creator:: Smith, Richard D. (Richard Dean), 1950-
Abstract:: A descriptive model of the routing of sediment that was delivered to the study area by the 1980 eruptions of Mount St. Helens has been developed. On hillslopes this sediment was distributed among three major storage compartments: 1) the tephra profile, 2) primary storage, and 3) secondary storage. The most...

A comparative assessment of four winter feeding programs for spring calving cow-calf ranches in the Harney Basin, Oregon

Creator:: Bates, Jonathan D.
Abstract:: The objective of this thesis is to assess four winter feeding programs of spring-calving brood cows that may improve profitability to ranching operations of the Harney Basin, Oregon. The four feeding strategies include strip grazed rake-bunched hay, supplemented range grazing, strip grazed meadow pasture, and baled hay feeding. These first...

An analysis of two post-Mazama prehistoric flaked stone scatters in the upper Deschutes River basin of central Oregon

Creator:: McFarland, Janine Ruth
Abstract:: During the summer of 1986, an archaeological testing project was completed at seven prehistoric campsites primarily located in the upper Deschutes River Basin of central Oregon. Testing was focused on two low-density "lithic scatters", an archaelogical site type which is especially abundant in this obsidian-rich region but which, to date,...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

Oregon's early peoples and their relation to the environment : an interpretive approach

Creator:: Possiel, William John
Abstract:: The dramatic upsurge of contract-supported archaeological activity, generated by legislative action, has precipitated an increase in information about Oregon's prehistoric peoples. This information, however, has not been presented in a format which can be easily understood by the general public. This study presents an account of early peoples in Oregon,...

The cultural significance of mountain regions : implications for the Calapooya Divide, Oregon

Creator:: Starr, Karen J.
Abstract:: Altitudinal variations in upland regions of the earth create variable climatic zones and conditions. Plant and animal communities must adapt to these conditions, and when they reach their tolerance limits for environmental conditions at the upper levels of a zone, they cease to exist in the environment. Humans also utilize...
