Comparisons of fish assemblages and habitat associations in littoral zones of reservoirs in the Willamette Basin, Oregon

Creator:: Bennett, Paul Michael
Abstract:: The littoral zones of seven reservoirs in the southern Willamette Valley of Oregon were sampled with a boat electroshocker during the summer months of 1995 and 1996. Shoreline substrates were inventoried before sampling sites were randomly selected. Sampling sites consisted of 9 of 12 possible habitat types including four substrate...

Fish and amphibian use of intermittent streams within the upper Willamette Basin, Oregon

Creator:: Colvin, Randall William
Abstract:: In the fall through spring of 2002/03 and 2003/04, the composition of fish and amphibian communities were examined in intermittent streams in the upper Willamette river basin in western Oregon. I recorded standard aquatic habitat variables and water nutrient concentrations (nitrate and phosphate) and correlated them with fish and amphibian...

A spatially explicit method for determining the effects of watershed scale land use on stream conditions

Creator:: Kehmeier, Jonathan W.
Abstract:: The primary goal of this research was to identify the impacts that individual agricultural land uses have on fish communities in small streams located in the Willamette Valley of western Oregon. The diverse nature of the land use features of the valley provided a challenging but useful system for the...

Willamette River Floodplain 100 Meter Slices Framework Technical Details: Fish Communities ca. 2010

Creator:: University of Oregon. Institute for a Sustainable Environment and Enright, Chris
Abstract:: The SLICES framework is intended for use in making decisions about conservation and restoration in the Willamette River floodplain. It makes use of distinct spatial units, called slices, for planning and tracking change in the floodplain. The Fish Communities ca. 2010 Technical Report describes the two associated attributes (field names:...

Habitat relationships of native and non-native fishes of the Willamette River, Oregon

Creator:: Williams, Joshua E.
Abstract:: The Willamette River flows north between the Cascade Mountains and Coast Range of western Oregon within a 29,728-km² basin. The fish community in the geologically young basin consists of 36 native species, but introductions of non-native fishes have added 33 additional species for a total of 69 fish species. During...

Quality of shallow ground water in alluvial aquifers of the Willamette Basin, Oregon, 1993-95

Creator:: Hinkle, Stephen R., National Water-Quality Assessment Program (U.S.), and Geological Survey (U.S.)
Abstract:: The purposes of this report are to describe the quality of shallow ground water in alluvial aquifers of the Willamette Basin and to identify relationships between shallow ground-water quality and various natural and anthropogenic factors. Several natural and anthropogenic factors (soil characteristics, cumulative thickness of clay above open interval of...

The Biology of the winter steelhead of the Willamette River, Oregon

Creator:: Clady, Michael D. (Michael David), 1942- and Oregon. State Game Commission. Research Division
Abstract:: This report the sizes for winter steelhead runs of the Willamette River and many of its tributaries from 1958-69, giving numbers and suggesting possible reasons for small runs.

Linkages among land use, riparian zones, and uptake and transformation of nitrate in stream ecosystems

Creator:: Sobota, Daniel J.
Abstract:: Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the biosphere during the past century from human activities. In this dissertation, I quantified uptake and transformation of nitrate (NO₃⁻)...

Optimizing Reservoir Operations to Adapt to 21st Century Expectations of Climate and Social Change in the Willamette River Basin, Oregon

Creator:: Moore, Kathleen M.
Abstract:: Reservoir systems in the western US are managed to serve two main competing purposes: to reduce flooding during the winter and spring, and to provide water supply for multiple uses during the summer. Because the storage capacity of a reservoir cannot be used for both flood damage reduction and water...
