Effects of Stage 0 treatment on spring Chinook juveniles within South Fork McKenzie River in Oregon

Creator:: Hahn, Aleah
Abstract:: Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...

Fish out of Water: Virgin Spinedace (Lepidomeda mollispinis) in the Santa Clara River, Utah

Creator:: Siefken, Sarah N.
Abstract:: River ecosystems throughout the arid southwestern U.S. are imperiled. Water management infrastructure, climate change, unsustainable water use, and political conflict harm the region's aquatic and riparian ecosystems. This case study surveys one such desert river, an endemic fish species, and conservation efforts in southwestern Utah. The analysis focuses on the...

Climate change in the Northwest : implications for our landscapes, waters, and communities

Creator:: Dalton, Meghan M., Mote, Philip W., Snover, Amy K., and Oregon Climate Change Research Institute
Abstract:: Climate Change in the Northwest: Implications for Our Landscapes, Waters, and Communities is a report aimed at assessing the state of knowledge about key climate impacts and consequences to various sectors and communities in the Northwest United States. This report draws on two recent state climate assessments in Washington in...

Oregon climate assessment report : December 2010

Creator:: Dello, Kathie D., Mote, Philip W., and Oregon Climate Change Research Institute
Abstract:: The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....

Stream Chemistry in the Oregon Coast Range: Spatial and Temporal Variation

Creator:: Carini, Lya
Abstract:: Hydrological and biogeochemical processes occurring throughout a watershed are typically reflected in stream water chemistry, including in coastal watersheds. While Oregon Coast Range streams have been studied in the past, there is a dearth of knowledge in terms of seasonal temporal trends and spatial variability that this study seeks to...

Ecohydrologic Connections in Semiarid Rangeland Ecosystems in Oregon

Creator:: Durfee, Nicole M.
Abstract:: An improved understanding of the ecohydrologic relationships in semiarid rangelands is imperative for the development of effective rehabilitation and land management practices. This thesis addresses the ecohydrologic relationships of two significant issues concerning semiarid rangeland ecosystems: western juniper encroachment and increasing stream temperatures. This thesis is divided into two chapters;...

The Relationship between Hydroregime and Coho Salmon (Oncorhynchus kisutch) Spawning in Three Streams of the Smith River Watershed, Oregon

Creator:: Baxter, Mackenzie R.
Abstract:: Migration and spawning phenology of Pacific Salmon is linked to the hydroregime, and thought to be triggered by increases in river discharge and decreases in water temperature. However, little data exists that describes direct fine-scale linkages between the hydroregime and spawning in Coho Salmon. This study evaluated the spatial and...

Assessing the Current State of Transboundary Cooperation in the International Columbia River Basin

Creator:: Timboe, Ingrid A.
Abstract:: The Columbia River Treaty (CRT) is often used as an example of how treaties can work to normalize, regulate, and improve the cooperative management of shared water resources between basin countries. Few would argue that, in its limited mandate to regulate hydropower generation and flood risk management for downstream communities,...

Cool, Pathogen-Free Refuge Lowers Pathogen-Associated Prespawn Mortality of Willamette River Chinook Salmon

Creator:: Benda, Susan E., Naughton, George P., Caudill, Christopher C., Kent, Michael L., and Schreck, Carl B.
Abstract:: Spring Chinook Salmon Oncorhynchus tshawytscha are transported above dams in the Willamette River to provide access to blocked spawning habitat. However, 30–95% of these transplants may die before spawning in some years. To varying degrees, salmon in other tributaries—both blocked and unblocked—have similar prespawn mortality (PSM) rates. Our study determined...

Pits, Politics, and People : Identifying Barriers to the Enhancement Reclamation of Floodplain Aggregate Mines in the Willamette Valley, OR

Creator:: Morrison, Elizabeth A.
Abstract:: Aggregate, which consists of crushed rock, sand, and gravel resources, is one of the most extracted resources in Oregon. Floodplain sites throughout the Willamette Valley -- particularly along the Willamette River -- are of particular importance because they produce high quality sand and gravel, located close to the aggregate market....
