Abstract:
Four species of Rhinichthys (R. cataractae, R. falcatus, R. osculus, and R. umatilla) are recognized in Canadian sections of the Columbia River, with sympatry occuring between all species except R. falcatus and R. osculus. Species status of the latter is supported by morphological dissimilarity between it and the morphologically similar R. falcatus and R. umatilla. Populations of R. umatilla from the Similkameen, Kettle, and Columbia (including Kootenay and Slocan) rivers have morphological and pigmentary differences, but are identifiable with R. umatilla of the lower Columbia River. Canadian R. osculus are similar to historically known populations near the Colville and Little Spokane rivers of northeastern Washington. Populations from more distant tributaries of the Columbia system are variable in morphology and habitat and require separate study to determine their relationships to Canadian populations. Rhinichthys osculus was apparently replaced by R. umatilla in the Colville River, an event that may have been correlated with historical changes of water quality or flooding by the Roosevelt Reservoir. Because R. umatilla prefers swift clear portions of large rivers, it is potentially in conflict with hydroelectric projects. Though not immediately threatened, the status of this species in Canada should be monitored in connection with future development of river systems.

Abstract:
Umatilla Dace (Rhinichthys umatilla, Cyprinidae) are endemic to the Columbia River Basin. In Canada, this species is assessed as “threatened”. Little is known about its life history, especially with respect to spawning in the wild. A total of 688 specimens were captured, including 39 mature males and females displaying spawning colouration and tubercles, during minnow trapping and electrofishing surveys conducted on the Slocan River in southern British Columbia, Canada. Fertilized eggs were not observed, but eggs and milt were expressed from ripe individuals. Spawning was estimated to occur from mid-July to mid-September. Aquatic macrophytes and flooded terrestrial vegetation were important habitat features for mature Umatilla Dace leading up to the spawning period on the Slocan River. To our knowledge this is the first time that Umatilla Dace have been captured in spawning condition and observed with spawning colouration and tubercles in the wild in Canada. Results of this study will aid the development of recovery plans and management for this species in British Columbia.

Abstract:
`Umatilla Russet' and `Russet Legend', two newly released potato (Solanum tuberosum L.) cultivars were compared with four established cultivars (`Russet Burbank', `Shepody', `Frontier Russet', and `Ranger Russet'). Potatoes were grown under four, season-long, sprinkler irrigation treatments in three successive years (1992-94) on silt loam soil in eastern Oregon. At each irrigation, the full irrigation treatment received up to the accumulated evapotranspiration (ETc) since the last irrigation. Three deficit irrigation treatments had progressively less water. The new cultivars `Umatilla Russet' and `Russet Legend' performed as well as or better than the other cultivars in the full irrigation treatment, with `Umatilla Russet' showing a higher yield potential at the higher water application rates than `Russet Legend'. All cultivars produced more U.S. No. 1 tubers than `Russet Burbank', except in 1993, an unusually cool and wet year. `Russet Legend' was the only cultivar showing a tolerance to deficit irrigation. In two out of the three years, `Russet Legend' was as productive of U.S. No. 1 yield over most of the range of applied water as `Shepody', `Frontier Russet', and `Ranger Russet' were at the higher end of the applied water range. Chemical names used: 0,0-diethyl S-[(ethylthio) methyl] phosphorodithioate (phorate); N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine (pendimethalin); and 2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1methyl-ethyl) acetamide (metolachlor).

Full text
Abstract:
Until the 1990s, salmon had been extinct from the Umatilla River for over 70 years. The struggle to bring salmon back to this river is a compelling story that exemplifies some of the new relationships in Columbia River Basin salmon management. The Umatilla River and the disappearance of its salmon was a local issue. Irrigation interests had used the river so thoroughly it ceased to flow during the late summer and fall months-precisely when salmon needed it for migration. The Confederated Tribes of the Umatilla Indian Reservation saw decided that they would change that: they would figure out a way to put both salmon and water back into the river. This thesis examines this process. First, it contextualizes the Umatilla River within the Columbia River Basin and Columbia Basin salmon management, and shows how a local salmon issue became a regional salmon issue. It then discusses the triangle of relationships that Indians, salmon, and hatcheries have come to form. Chapter III discusses the formation of the unique Umatilla Fish Restoration Program, which reintroduced fish into the river, and was paid for by the Bonneville Power Administration (BPA), as per the Northwest Power Act. Key elements within BPA's Fish and Wildlife Division resisted complying with the directives of the Northwest Power Planning Council to pay for the Program, setting the Program back years. I argue that this comes from two clashing ways of seeing the River: "cost-benefit analysis" versus "least cost." Chapter IV looks at the new partnerships formed in the Umatilla River Basin by the Tribes and irrigation districts in order to encourage the U.S. Bureau of Reclamation to construct a water delivery system that would satisfy irrigators while allowing most of the Umatilla to flow freely. The last Chapter suggests that these new and somewhat ironic partnerships between federal and state governments, private irrigators and landowners, nongovernmental organizations, and Indian tribes are key to restoring ecosystems in the Columbia River Basin. It further argues that without tribal nations playing an active role and exerting their treaty rights, restoring rivers like the Umatilla is impossible.

Abstract:
An examination of the history of transportation in Umatilla County, Oregon, will provide an understanding of its role in the colonization and economic development of this remote and arid reg10n. This study begins with a description of the movement of Umatilla, Walla Walla, and Cayuse Indians in the Umatilla Country to establish the patterns of transportation at the beginning of the nineteenth century. From this basis, significant changes in transportation technology and patterns of movement can be identified and analyzed. Primary sources are reviewed to establish existing routes and conditions of travel. Immigrant accounts and pioneer reminiscences reveal that difficulties with transportation were identified very early as the major obstacle to the development of an agriculture-based market economy. Umatilla County archives provide a clear record of the actions taken by the county government to lay out and maintain wagon roads. Three significant changes are identified in nineteenth century transportation in Umatilla County: introduction of the horse, introduction of wheeled vehicles, and the coming of steampowered vessels and trains. Each of these three developments were revolutionary, adding to the capacity and range of the existing transportation system. The sudden demands for transportation as a result of gold strikes east and south of Umatilla County created the need to expand the regional transportation system. That expanded system was then available to new settlers. As the dominant land use was transformed from livestock grazing to dryland wheat farming, the need for railroads, in addition to Columbia River steamboats, became clearly evident. Feeder roads remained very important, as did animal traction to pull the wagons to the warehouses and loading docks along the rail lines. The location of major routes of travel across the Umatilla Indian Reservation resulted in significant problems for the transportation system. The system to establish and maintain county roads, mandated by state law, involved direct participation of individuals residing adjacent to the roads. Throughout the nineteenth century, the patterns of movement remained remarkably unchanged. Based on ancient Indian trails, the transportation system was the crucial element m the economic development of Umatilla County.

Abstract:
In the late nineteenth and early twentieth centuries, the United States government, in its relations with Native Americans, implemented a policy of assimilation designed to detribalize Indian peoples and absorb them into the dominant society. Subjected to this colonial agenda, the Cayuse, Walla Walla, and Umatilla tribes of Oregon's Umatilla Indian Reservation, as a matter of survival, endeavored to maintain community cohesion and retain their indigenous identity. In this context, I argue that the tribes confronted federal initiatives with a strategy of adaptive resistance that allowed them to approach these onerous impositions on their own terms. This study examines their diverse responses to assimilation and colonialism, specifically accommodation, adaptation, and diplomacy. Employing the investigative frameworks of education, religion, and economics reveals the variety of tactics applied within these categories, which range from incorporation to evasion. Through these actions and reactions, the tribes reaffirmed their capacity to assert native agency.

Brown, Elizabeth Ann. "Rhyolite Petrogenesis at Tower Mountain Caldera, OR." PDXScholar, 2017. https://pdxscholar.library.pdx.edu/open_access_etds/3997.

Full text
Abstract:
Tower Mountain Caldera is the main feature of an Oligocene volcanic field located in the Umatilla National Forest, eastern Oregon. It is perfectly suited to investigate models of rhyolite petrogenesis as all of the important rock components for evaluating generation models are present in a single location and thus are presumably related; basalts, intermediate igneous rocks (which consist of older plutons and younger volcanic rocks, which are ~coeval with rhyolites), metamorphic basement rocks of significant grade, and rhyolites of varying composition. The formation of the caldera produced the Dale Tuff, which comprises the intra-caldera and outflow facies. 40Ar/39Ar dating places the age of the tuff at 32.66 ± 0.36 Ma. Post-caldera rhyolites erupted along apparent ring fractures and elsewhere. Radiometric U-Pb dating of zircons from three of these rhyolites yielded ages of 32.167 ± 0.020 Ma (#CH07a), 31.798 ± 0.012 Ma (#TM5), and 31.426 ± 0.016 Ma (#CH08a). All rhyolites at Tower Mountain range from low to high silica varieties. Some of the post-caldera rhyolites are chemically similar to the Dale Tuff, such as sample CH07a, and have compositions typical of rhyolites of calc-alkaline volcanic centers (I-type rhyolites), while others are similar to A-type rhyolites (CH08a and TM5). The ages indicate that the calc-alkaline rhyolites were followed by the A-type rhyolites. The petrogenetic relationships between the various rocks types were evaluated. Partial melt modeling based on experimental melts produced from crustal material indicates that batch partial melting of metamorphosed high silica crustal material modified by the addition of more primitive mafic material by assimilation/contamination is the most likely source for the Tower Mountain rhyolites.

"The use of Hydrochemistry to Identify Potential Processes Operating in the Saddle Mountains Basalt Aquifer and the use of the Nitrate-nitrogen Isotope to Distinguish between Potential Sources of Nitrate to the Shallow Alluvial Aquifer in the Lower Umatilla Basin, Oregon." PDXScholar, 1996. https://pdxscholar.library.pdx.edu/open_access_etds/5206.

Full text
Abstract:
Nitrate concentration in excess of national drinking-water standards (10 mg/l) are present in the shallow alluvial aquifer and Saddle Mountains Basalt (SMB) aquifer in the Lower Umatilla Basin, Oregon. To determine sources responsible for elevated nitrate concentrations in the SMB aquifer mass-balance and reaction-path models (NETPATH and PHREEQE) were used to understand observed geochemical trends. Nitrate-nitrogen isotopes were used to distinguish potential nitrate sources in the shallow alluvial aquifer. NETPATH-validated simple water/rock reactions in the SMB aquifers in Irrigon (dissolving glass, precipitating smectite, dissolving or precipitating calcite, and cation exchange) using constituents (calcium, magnesium, sodium and carbon). Diversity of composition for the shallow alluvial water and limited number of wells available made obtaining a mass balanced solution for the SMB aquifer near Boardman impossible. Irrigon basalt groundwaters were consistent with the PHREEQE models prediction of natural hydrochemical trends, where Boardman basalt groundwaters plotted consistently with impacted alluvial groundwater. Nitrogen-isotopic values of nitrate (o 15NNo3) were measured in the shallow alluvial groundwater from 17 wells in 4 land-use settings, 3 lysimeter samples and 1 surface water effluent sample. The landuse setting and corresponding average ranges for nitrate concentrations (as N) and 015NNo3 values for wells near: commercial fertilizer-irrigated fields range from 25-87 mg/l, +3.5 to +4.6 per mil; explosive washout lagoons ranged from 10-18 mg/l, +4.6 to +4.9 per mil; potato waste water application ranged from 6.4-17.8 mg/l, +4.4 to +35 per mil; past confined animal feeding operations (CAFO) ranged from 16-56 mg/l, +4.9 to 10.4 per mil; lysimeters 5.4-39.9 mg/l, +9.1 to +21.9 per mil; surface water effluent ranged from 60-61 mg/l, +3.5 to 6.5 per mil; and varying landuse ranged from 9.3-19.5 mg/l, +2.7 to +7.1 per mil. Commercial fertilizer 0 15NNo3 signatures are consistent for this source. Explosive 015NNa3 values are consistent with an atmospheric signature. CAFO o15NNo3 signatures probably result from mixing between currently applied commercial fertilizer and past CAFO's. High 015NNo3 Signatures (+22 to +35 per mil) imply denitrification. Potato waste water and varying land-use 015NNo3 signatures indicate probable mixing of nitratenitrogen sources in the groundwater.

The study found the difference was not significant when comparing the use of solution frames between The Hermiston Herald and The Oregonian. In addition, there was not a significant difference in use of pluralistic framing by The Hermiston Herald and The Oregonian. However, there was a significant difference in the sources presented in the newspaper articles. There was also a significant presence of episodic frames compared to thematic frames in both the newspapers under examination.

Full text
Abstract:
This study provides an analysis of watershed response to climate change and forest fire impacts, to better understand the hydrologic budget and inform water management decisions for present and future needs. The study site is 2,365 km2, located in the upper Umatilla River Basin (URB) in northeastern Oregon. The Precipitation Runoff Modeling System, a distributed-parameter, physical-process watershed model, was used in this study. Model calibration yielded a Nash Sutcliffe Model Efficiency of 0.73 for both calibration (1995-2010) and validation (2010-2014) of daily streamflow. Ten Global Climate Models using Coupled Model Intercomparison Project Phase 5 experiments with Representative Concentration Pathways 4.5 and 8.5 (RCP), were used to observe hydrologic regime shifts in the 2020s, 2050s, and 2080s. Mean center timing of flow occurs earlier in the year in both pre- and post-fire conditions, where there are increased winter flows and decreased summer flows throughout the 21st century. Change in temperature and percent change in precipitation is more variable in the summer than winter increasing over time, with a slight decrease in winter precipitation in the 2080s in RCP 8.5. Temperature increases 1.6°C in RCP 4.5 and 3.3°C in RCP 8.5 by the end of the 21st century. The ratio of Snow Water Equivalent to Precipitation decreases 96% in the 2080s in RCP 8.5 before forest cover reduction, and decreases 90-99% after forest cover reduction. Potential basin recharge and the base-flow index are both sustained throughout the 21st century with slight declines before forest cover reduction, with an increase in basin recharge and increase in base-flows in the 2080s after fire-burns. However, the simulated sustained base-flows and area-weighted basin recharge in this study, do not take into account the complex geologic structure of the Columbia River Basalt Group (CRBG). A more robust characterization and simulation of URB aquifer recharge would involve coupling the PRMS model with a groundwater model in a future study. Although groundwater recharge in the CRBG in the URB is not well understood, the long-term decline of groundwater storage presents a serious environmental challenge for the Confederated Tribes of the Umatilla Indian Reservation and communities in the URB.

Abstract:
<em>Abstract</em>.—Between 1999 and 2007, more than 2,600 adult Pacific lampreys <em>Entosphenus tridentatus </em>(formerly <em>Lampetra tridentata</em>) were reintroduced to the Umatilla River, where they had been extirpated by poisoning, from nearby locations in the Columbia River consistent with the International Union for Conservation of Nature and Natural Resources guidelines. Reintroduced adult Pacific lampreys were able to find suitable spawning habitat, construct nests, and deposit viable eggs (81–93% mean egg viability per nest). Their larvae were able to feed and grow. Median lengths for age 0+, 1+, and 2+ larvae were 19, 63, and 109 mm, respectively. Mean density of larvae in survey plots increased over time from 0.08 to 6.56 larvae/m<sup>2</sup>. Geographical distribution of larvae in the river increased downstream, but larvae failed to become established in the lower Umatilla River where water flows were regulated for irrigation. Annual abundances of trapped, recently metamorphosed, out-migrating larvae increased during the study from nearly zero to 180,000, but not in all years, which suggests that many might not be surviving migration to the Columbia River, possibly because of irrigation withdrawals. Abundances of trapped, returning adult lamprey also increased from 2003 to 2006, which corresponded with the period when adult lampreys that were the progeny of reintroduced lampreys were expected to return, but long-term monitoring is necessary to confirm that increases were the result of the reintroduction. Our results also demonstrated that even if presumptive causes of extirpation were known and removed before reintroduction, success is not guaranteed. Reintroduction not only assists in redistributing animals to parts of their historical range, but in conjunction with monitoring, it may be essential to identify additional limiting factors that were unknown at reintroduction.

Abstract:
<em>Abstract.</em>—Since 1982, the Columbia River Treaty tribes (Yakama, Nez Perce, Umatilla, and Warm Springs) have proposed the use of hatcheries as a tool to recover naturally spawning populations throughout the Columbia basin. The Yakama Nation is working with the support of other agencies to implement tribal salmon restoration philosophies and proposals in the Yakima River basin. Yakima/Klickitat fishery project biologists estimate that the Cle Elum supplementation project has boosted populations of upper Yakima spring Chinook salmon <em>Oncorhynchus tshawytscha </em>by about 90% in both 2001 and 2002 over what returns would have been without the innovative hatchery. With the benefit of added fish from the Cle Elum supplementation project, the spring Chinook redd count in the Teanaway River in 2002 was more than five times the highest count in recorded history. Yakama Nation efforts to re-establish a sustainable, naturally spawning coho salmon <em>O. kisutch </em>population in the Yakima basin have resulted in adult coho returns that averaged nearly 5,000 fish from 1998 to 2001 (an order of magnitude greater than the prior 10-year average), including an estimated return of more than 1,500 wild/natural coho to the Yakima River basin in 2001. Yakama Nation steelhead <em>O. mykiss </em>kelt reconditioning programs have increased the escapement of steelhead to spawning grounds in the Yakima basin by 2.4% for the 2001–2002 migration and by 7.3% for the 2002–2003 migration. While it is not yet possible to definitively state whether or to what extent the use of hatchery reared fish and/or methods has resulted in these successes without causing other adverse ecological consequences, intensive monitoring and evaluation efforts continue on these projects and formal scientific results will be published as definitive results become available.

Abstract:
ABSTRACT In late Wisconsin time, the Purcell Trench lobe of the Cordilleran ice sheet dammed the Clark Fork of the Columbia River in western Montana, creating glacial Lake Missoula. During part of this epoch, the Okanogan lobe also dammed the Columbia River downstream, creating glacial Lake Columbia in northeast Washington. Repeated failure of the Purcell Trench ice dam released glacial Lake Missoula, causing dozens of catastrophic floods in eastern Washington that can be distinguished by the geologic record they left behind. These floods removed tens of meters of pale loess from dark basalt substrate, forming scars along flowpaths visible from space. Different positions of the Okanogan lobe are required for modeled Missoula floods to inundate the diverse channels that show field evidence for flooding, as shown by accurate dam-break flood modeling using a roughly 185 m digital terrain model of existing topography (with control points dynamically varied using automatic mesh refinement). The maximum extent of the Okanogan lobe, which blocked inundation of the upper Grand Coulee and the Columbia River valley, is required to flood all channels in the Telford scablands and to produce highest flood stages in Pasco Basin. Alternatively, the Columbia River valley must have been open and the upper Grand Coulee blocked to nearly match evidence for high water on Pangborn bar near Wenatchee, Washington, and to flood Quincy Basin from the west. Finally, if the Columbia River valley and upper Grand Coulee were both open, Quincy Basin would have flooded from the northeast. In all these scenarios, the discrepancy between modeled flood stages and field evidence for maximum flood stages increases in all channels downstream, from Spokane to Umatilla Basin. The pattern of discrepancies indicates that bulking of floods by loess increased flow volume across the scablands, but this alone does not explain low ­modeled flow stages along the Columbia River valley near Wenatchee. This latter discrepancy between modeled flood stages and field data requires either additional bulking of flow by sediment along the Columbia reach downstream of glacial Lake Columbia, or coincident dam failures of glacial Lake Columbia and glacial Lake Missoula.
