  Citation × Citation Citation Abstract Copy Title: Thomas Creek Mainstem Assessment Completion Report Abstract -- This project expands upon a year 2000 project (OWEB 99-543) that was designed to examine riparian and water quality impacts on aquatic invertebrate assemblages and fish diet in Thomas Creek. The initial project design was to sample water quality, fish, and invertebrates at nine sites along 30 river kilometers (R kms) of the stream; three in conifer dominated, three in mixed forest, and three in hardwood dominated riparian forest. Preliminary results suggested water quality conditions were similar throughout the 30 R kms and riparian vegetation composition was not associated with fish diet or invertebrate assemblage composition. Longitudinal patterns were weak and appeared to be driven by three upstream sites. Therefore we proposed to expand the survey area to include the entire stream open to anadromous fish migration (51 R kms). The fish diet portion of the project was discontinued because we were denied a sampling permit for ESA listed salmonids during 2001. Instead, we focused on broad-scale fish distribution and habitat use. Additionally, we compared patterns for fish with invertebrates. The extent of fish, invertebrate, and water quality sampling locations increased to include all 51 R kms downstream of the waterfall. An extensive fish survey to examine fish distribution included 218 survey locations throughout the 51 R kms. Intensive snorkel surveys to examine fine-scale, habitat use by salmonids included four sample locations in the upstream 14 R kms. Invertebrate samples were collected from three habitat types at 27 sites to examine distribution and habitat use along the 51 R kms Title: Thomas Creek Mainstem Assessment Completion Report Abstract -- This project expands upon a year 2000 project (OWEB 99-543) that was designed to examine riparian and water quality impacts on aquatic invertebrate assemblages and fish diet in Thomas Creek.

  Citation × Citation Citation Abstract Copy Title: Work Completed for Compliance with the Biological Opinion for Hatchery Programs in the Willamette Basin USACE funding: 2004 Annual Report Abstract -- The National Marine Fisheries Service (NMFS) has listed spring chinook salmon(Oncorhynchus tshawytscha) and winter steelhead (O. mykiss) in the Upper Willamette River Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act (ESA; 64 FRN 14308; 64 FRN 14517). Concomitant with this listing, any actions taken or funded by a federal agency must be evaluated to assess whether these actions are likely to jeopardize the continued existence of threatened and endangered species, or result in the destruction or impairment of critical habitat. Several fish hatcheries operate within the ESU and may impact wild populations of listed species. Although all of the artificial propagation programs that potentially affect listed salmonids in the Upper Willamette River ESUs are operated by the Oregon Department of Fish and Wildlife(ODFW), 90% of the funding for these operations comes from the U.S. Army Corps of Engineers (COE). Possible risks of artificial propagation programs have been well documented. Hazards include disease transfer, competition for food and spawning sites, increased predation,increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, providing a genetic reserve in the case of extirpation, and providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects of hatchery programs on naturally spawning populations of spring chinook and winter steelhead within the Upper Willamette River ESU. The project employs four types of activities to achieve this goal: sampling of returns to hatcheries, creels to assess fisheries, monitoring of adult and juvenile migration through the use of traps and video observations, and monitoring natural production through spawning ground surveys.

  Citation × Citation Citation Abstract Copy Title: Little Deschutes Subbasin Watershed Assessment Abstract -- Many of the impacts to fish and wildlife habitat and water quality in the Little Deschutes River Subbasin are concentrated in the areas of housing, roads, and other human development. Most of the human population in the subbasin is concentrated around the community centers of La Pine, Gilchrist, Crescent, and Crescent Lake. There is significant dispersed development along the lower reaches of the Little Deschutes River between the communities of Sunriver and La Pine -an area characterized by gentle topography and depressions with forested wetlands, marshes and shallow lakes. Streams in this area, as illustrated by the Little Deschutes River , are low gradient and originate in the high elevation areas in the southwest portion of the watershed where there is higher precipitation. This ownership pattern has significant implications for natural resource management, as lower gradient floodplain areas tend to provide important wetland, fish, and wildlife habitat. Key Findings Fuel Loading: Having homes safe from wildfires is a concern for many residents. Fire suppression has increased the amount of dry wood in the area, creating a ready source for major wildfires. Riparian Areas and Wetlands: Loss of wetland and riparian areas , especially in the lower areas along the Little Deschutes River , has affected a number of resources. Water quality has been affected by the reduced wetlands that act as filters of nitrogen; the loss of streamside trees and other vegetation reduces shade that helps to cool water temperatures. Finally, loss ofwetlands and riparian vegetation has reduced important fish and wildlife habitats. Wildlife: The growth and development have altered wildlife habitats. Loss of wetlands, streamside vegetation, and other changes in the watershed have reduced important wildlife habitat. Roads and development have impacted migrating mule deer, increasing collisions between deer and cars and altering their migration pathways. Fish: There has been a significant loss of native trout and an increase in introduced brook and brown trout in the Little Deschutes River and tributaries. Loss of native trout is from competition with introduced species and changes in aquatic habitat and water temperatures. Water Quality: A major concern about the water in the river is unusually high temperatures in the summer and the abnormal growth of algae. Other studies indicated that there are problems with groundwater loading ofnitrogen. The high water table (with associated wetlands), and porous pumice soils contributes to increased nitrates, a by-product of septic systems and an indicator of human pathogens.
