Environmental correlates of parasitism in introduced threespine stickleback (Gasterosteus aculeatus) in the Upper Deschutes River Basin, Oregon

Creator:: Koketsu, Wataru
Abstract:: The Pseudophyllidean tapeworm, Schistocephalus solidus, is a parasite that requires both copepods and fish, mainly the threespine stickleback (Gasterosteus aculeatus) as intermediate hosts, and birds as its final host to complete its life cycle. A rapid increase in the abundance of both the non-native stickleback and the tapeworm in the...

Stratigraphy, sedimentology, and petrology of neogene rocks in the Deschutes basin, central Oregon : a record of continental-margin volcanism and its influence on fluvial sedimentation in an arc-adjacent basin

Creator:: Smith, Gary Allen
Abstract:: Neogene rocks of the Deschutes basin include the middle Miocene Columbia River Basalt Group and Simtustus Formation, and late Miocene to early Pliocene Deschutes Formation. Assignment of Prineville chemical-type flows to the Grande Ronde Basalt of the Columbia River Basalt Group is based upon correlation of these lavas from their...

Life history variation and movement among three populations of redband trout (Oncorhynchus mykiss gairdneri) in the middle Deschutes Basin, Oregon

Creator:: Groves, Kristy L.
Abstract:: Redband trout (Oncorhynchus mykiss gairdneri) are found over a wide range of environmental conditions and are known for their variability in life history traits among watersheds or even within streams. Life history traits and population structure of these trout can be influenced by a variety of anthropogenic changes including habitat...

Identification of economic, social, and policy factors influencing irrigation district participation in water transactions in the Deschutes Basin

Creator:: Whitman, Cally A.
Abstract:: Surface water in the Deschutes Basin of central Oregon has been largely over allocated since the early 1900s. Therefore, rapid population growth and urban demand for water in the upper Basin lead to an increased reliance on groundwater in the last three decades. The Oregon Department of Water Resources (OWRD)...

Upper Deschutes River Basin Prehistory: A Preliminary Examination of Flaked Stone Tools and Debitage

Creator:: Taggart, Michael W.
Abstract:: The prehistory of Central Oregon is explored through the examination of six archaeological sites and two isolated finds from the Upper Deschutes River Basin. Inquiry focuses on the land use, mobility, technological organization, and raw material procurement of the aboriginal inhabitants of the area. Archaeological data presented here are augmented...

Effects of kokanee (Oncorhynchus nerka) redd superimposition on bull trout (Salvelinus confluentus) reproductive success in the Deschutes River Basin, Oregon.

Creator:: Weeber, Matthew A.
Abstract:: Oregon's only remaining non-reservoir population of adfluvial bull trout (Salvelinus confluentus) is found in Odell Lake, in the headwaters of the Deschutes River. The population size is unknown, but appears to be quite small. Limited spawning and rearing habitats, combined with the effects of introduced species and other anthropogenic changes...

Modeling Elevation-Dependent Snow Sensitivity to Climate Warming in the Data Sparse Eastern Oregon Cascades

Creator:: Cooper, Matthew Guy
Abstract:: In the mountains of the Western US, shifts in the timing and magnitude of snow water equivalent (SWE) over the past century are well documented and attributed to climate warming, but the magnitude of sensitivity depends on elevation. We modeled the spatial distribution of SWE and its sensitivity to climate...

Taming the Tumalo : A Damned Dam Repurposed for Recharge

Creator:: Harpham, Kelsey
Abstract:: The Tumalo Project at Tumalo Reservoir in Central Oregon was proclaimed a failure almost as soon as it was completed. As the reservoir filled with water diverted from Tumalo creek in the spring of 1915, sinkholes developed in the reservoir floor and every last drop of captured water disappeared into...

Risk assessment : introduction and establishment of Myxobolus cerebralis in the Deschutes River Basin, Oregon, USA

Creator:: Zielinski, Christopher
Abstract:: A plan for the reestablishment of anadromous salmonid stocks into waters above the Pelton Round Butte Hydroelectric Project (PRB) located on the Deschutes River, Oregon has been under development since 1996. The PRB complex, starting at river kilometer (Rkm) 103, blocks the further upstream migration of anadromous salmonids into upper...
