Assessment of water quality, nutrients, algal productivity, and management alternatives for low-flow conditions, South Umpqua River basins, Oregon, 1990-92 - Tanner, D. Q. (Water-Resources Investigations Report, 1996)
“This report is an evaluation of the effects of nutrient loading on water quality in the South Umpqua River Basin. . . . Five wastewater-treatment plants were shown to contribute less than 15 percent of the flow, but more than 90 per-cent of the nitrogen and phosphorus, in the South Umpqua River during low streamflows in summer. These nutrient inputs were associated with, and largely responsible for, the dense growth of periphytic algae that covered the rocky channel and produced biomass values as large as 340 grams of ash-free dry weight per square meter.” (from the Abstract) Algal respiration at night depleted dissolved oxygen, while daytime photosynthesis caused water pH to exceed the Oregon standard.

Pinniped Food Habits in Oregon - Riemer, Susan D.; Brown, Robin F. (Oregon Dept. of Fish and Wildlife. Marine Mammal Project, 1996)
“The purpose of this investigation was to determine if pinniped feeding patterns have significant negative impacts on depressed salmonid stocks. Knowledge about prey selection by pinnipeds is key to assessing their potential impact on salmonid stocks. The four major work elements reported are: 1) the reanalysis of Columbia River area scat samples collected in the early 1980's; 2) examination of California sea lion (Zalophus califonianus), Pacific harbor seal (Phoca vitulina), and Steller sea lion (Eumetopias jubatus) scat; 3) determination of salmonid size from recently collected gastrointestinal tract samples from the Columbia River; and 4) examination of previously collected pinniped scat samples from the southern Oregon coast. In addition pinniped prey items were identified from previous scat collections made in Siletz Bay, Alsea Bay, and the Umpqua River, along with a comparison of lavage, enema and scat samples collected in the Columbia River” (from the Abstract).

Status review of West Coast steelhead from Washington, Idaho, Oregon, and California - Busby, Peggy J.; Wainwright, Thomas C.; Bryant, Gregory J.; Lierheimer, Lisa J.; Waples, Robin S.; Waknitz, F. William; Lagomarsino, Irma; U.S. National Marine Fisheries Service. Northwest Fisheries Science Center,; U.S. National Marine Fisheries Service. Southwest Region. Protected Species Management Division, (NOAA Technical Memorandum NMFS-NWFSC, 1996)
Steelhead in the southern half of the state were doing a little better than northern Oregon steelhead. Umpqua estuary winter steelhead run trend varied from -0.5% (North Umpqua) to -0.8% (South Umpqua) to -1.7% (Smith River) per year. The North Umpqua summer steelhead run was actually trending upwards (+1%/year). Although the Smith River receives Alsea River hatchery fish, the Umpqua River is planted only with its own stocks. The North Umpqua summer steelhead run is a native run -- most other Oregon summer steelhead runs were introduced from the Siletz River. Authors estimated that from 10-62% of spawning steelhead in these streams were of hatchery origin. Hatchery practices (past and present) identified as major threat to genetic integrity for steelhead in this area.

Restoration strategies for the Umpqua Basin - Nehlsen, Willa (Sea-Run Cutthroat Trout Biology, Management, and Future Conservation Proceedings of a Symposium, 1995)
The author argues for an ecosystem approach to restoration of the Umpqua Basin. "The initial focus would be on relatively intact ecosystems and currently productive areas (the key watersheds, aquatic diversity areas, and source areas), with a restoration strategy building outward from these anchors. It could be argued that such a strategy would likely benefit not only sea-run cutthroat, but also other salmonids." (from the Abstract)

Ted (Sea-Run Cutthroat Trout : Biology, Management, and Future Conservation : Proceedings of a Symposium, 1995)
Winchester Dam fish counts show, "From 1946 to 1956, an average of 950 adults passed the dam per year. The run declined precipitously in the late 1950s, followed by a sharp increase in the 1960s and early 1970s during the period when natural fish were supplemented with hatchery releases. In the late 1970s, the run precipitously declined again, and has averaged only 62 adults per year since 1977." (Abstract, p.87) This species was listed as endangered in August, 1966.

1993 Calf Creek Migrant Trapping Results and Juvenile Steelhead (Oncorhynchus mykiss) Emigration Estimate - Harkleroad, Glenn R. (Umpqua National Forest, North Umpqua Ranger District, 1994)
Juvenile steelhead in Calf Creek display a "partial rearing life history." When stream levels drop, they migrate into the North Umpqua River. Instead of heading directly to the ocean, they may stay in the river for 1-2 years, before heading to sea. "This means that resource managers must not only be aware of potential impacts put upon them by management activities within the Calf Creek basin, but they must also be aware of factors influencing water quality and fish habitat in the North Umpqua River where the fish may reside for an important developmental portion of their lives. Therefore, management for Calf Creek steelhead includes management of' potential cumulative watershed effects of land management activities in the North Umpqua River basin above and below Calf Creek."

1994 Proposed Coastal Barrier Resources System Maps [cartographic resource] : State of Oregon - United States. Fish and Wildlife Service, (U.S. Fish and Wildlife Service, Region 1, 1994)
Coastal barriers are landforms that protect mainlands and aquatic habitats against the worst effects of coastal storms. Coastal barriers include estuaries, inlets, marshes, wetlands and nearshore waters and can include islands, sandspits, sandbars and broad beaches. The protective value of these landforms can be degraded by development. In 1994, a proposal was made to expand the Coastal Barrier Resources System to include the West Coast of the United States. These maps were drafted to show areas that should be protected. The proposed expansion, however, did not take place. Nevertheless, the maps have value in showing what should not be developed.

Status review for Oregon's Umpqua River sea-run cutthroat trout - Johnson, Orlay W.; Waples, Robin S.; Wainwright, Thomas C.; Neely, Kathleen G.; Waknitz, F. William; Parker, L. Ted (NOAA Technical Memorandum NMFS-NWFSC, 1994)
"Although the pattern of abundance and tag/recovery data during the period of supplementation indicated that Alsea River hatchery fish returned as adults to Winchester Dam in some numbers, it is apparent that 15 years of hatchery releases did not result in a viable, self-sustaining population of naturally spawning fish. The unresolved issue is, What do the few remaining anadromous O. clarki represent: remnants of the original Umpqua River gene pool, descendants of the Alsea River hatchery fish, or a mixed lineage? The run-timing shift suggested that an indigenous component may remain." (from the Abstract) This publication discusses the issues surrounding a possible listing of Umpqua River sea-run cutthroat trout. The species was listed as endangered in August, 1996.

Prehistoric seal and sea-lion butchering on the southern Northwest Coast - Lyman, R. Lee (American Antiquity, 1992)
Mammal remains from the Seal Rock and Umpqua Eden sites were analyzed. The analysis included examination and study of butchering marks on bones and includes insights on butchering techniques and transportation of animal remains. The author compares remains of adult Stellar sea lions from Seal Rock with harbor seal remains from Umpqua Eden. Most of the seal remains were of newborns, so the difference in size between the two types of marine mammals is great, yet the butchering techniques seemed similar. “Remains of two taxa of pinnipeds of markedly different body size from two sites of similar age on the southern Northwest Coast of North America do not vary significantly in skeletal parts represented, which suggests similar transport histories.” (from the Abstract)

The problem of channel erosion into bedrock - Seidl, M. A.; Dietrich, W. E. (Functional Geomorphology: Landform Analysis and Models: Festschrift for Frank Ahnert, 1992)
Tests rule for predicting rate of erosion into bedrock in the Siuslaw, Umpqua and Alsea basins. Steeper slopes deviated from the rule, probably due to debris flows scouring tributaries. Results suggest three mechanisms for bedrock erosion: vertical wearing; debris flow scouring; and sharp changes in channel slope (knickpoint propagation).

At the time of this publication, the Umpqua's population of wild coho salmon was considered "Depressed." Special concern was noted regarding the North Fork of the Umpqua River because of hatchery strays. The wild fall Chinook population was deemed "Healthy." Chum salmon populations on the Lower Umpqua River and the Smith River were of "Special Concern," and biologists noted that they may not be "valid population[s]." The status of the wild winter steelhead population on the Smith River was judged "Depressed," while the run on the North Fork of the Umpqua River was "Healthy." The summer steelhead run on the North Fork Umpqua River was also "Healthy."

Summertime Water Temperature Trends in Steamboat Creek Basin, Umpqua National Forest - Holaday, Steven A. (Oregon State University, 1992)
"This study was undertaken to: (1) determine long-term trends over the period 1969-90 of summertime water temperatures in the mainstem of Steamboat Creek, selected tributaries, and in Boulder Creek, an unharvested control stream in an adjacent watershed and (2) evaluate spacial patterns of maximum water temperatures in the Steamboat Creek basin during the summer of 1990." (from the Abstract) Found that, while low-water temperatures in the basin are high, as forest management practices evolved, stream temperatures in the basin decreased. Continued protection of riparian vegetation is necessary, particularly for steelhead trout.

Analysis and modeling of long-term stream temperatures on the Steamboat Creek Basin, Oregon: implications for land use and fish habitat - Hostetler, S. W. (Water Resources Bulletin, 1991)
The Steamboat Creek watershed is both an important source of timber and provides critical spawning and rearing habitrat for steelhead trout. This study compares Steamboat Creek Basin stream temperatures from 1969-1989 with an unlogged watershed, Boulder Creek. While Boulder Creek stream temperatures remained unchanged, temperatures in most Streamboat Creek streams dropped over the period studied, indicating a partial recovery still in progress of riparian vegetation following logging.

Distribution, Abundance, and Emigration of Juvenile Steelhead (Oncorhynchus mykiss), and Analysis of Stream Habitat in the Steamboat Creek Basin, Oregon - Dambacher, Jeffery M. (Oregon State University, 1991)
"Snorkel dive estimates and an inventory of stream habitat of the juvenile steelhead (Oncorhynchus mykiss) population in the Steamboat Creek basin were made in the summers of 1987 and 1988. Emigration was monitored by fish trapping from spring through fall of 1988. Distribution, abundance, and habitat utilization of juvenile steelhead were affected by stream size and temperature. . . I suggest that parr emigration from Steamboat Creek may be a life history adaptation that takes advantage of rearing conditions downstream in the North Umpqua River." (from the Abstract)

Urban storm runoff in the Roseburg Area, Oregon, as related to urban flood characteristics of the Willamette Valley - Hubbard, L. E. (Water-Resources Investigations Report / U.S. Geological Survey, 1991)
"Techniques are provided for estimating flood magnitudes for streams in the urbanized parts of the Roseburg, Oregon area for exceedance probabilites (recurrence intervals) of 0.5 (2-year), 0.2 (5-year), 0.1 (10-year), 0.04 (25-year), 0.02 (50-year) and 0.01 (100-year). A network of four continuous-recording streamflow gages, three crest-stage gages, and six precipitation gages was established and operated for a 3- year period (1982 to 1984). A U.S. Geological Survey rainfall-runoff model was calibrated for each site where runoff was measured and was used to produce a series of synthetic flood peaks." (from the Abstract)

Climatic change, spring Chinook, and human seasonal movements in the upper basin of the South Umpqua River: the Times Square Rockshelter model - Spencer, Lee (Northwest Anthropological Conference, 1990)
Print of paper given at conference. It is not known if this paper was ever published. Relates history of human use of the Times Square Rockshelter over almost 4,000 years to what is known about the climate. Unfortunately, not enough was known about the climate in the region of the rockshelter to definitely link patterns of use to fluctuations between xeric and mesic climate regimes, but the author believes that the data from the rockshelter can help to "serve as a basis for model building." (p.3). Maps, charts, tables.

A Phenotypic Comparison of Thirty-Eight Steelhead (Oncorhynchus mvkiss) Populations from Coastal Oregon - Hatch, Keith Martin (Oregon State University, 1990)
Shifts in fish genetics can show how fish interact with their environment. Here, the author looks at coastal steelhead and finds some differences, both in terms of basin size and geographical area. The author notes that, “Steelhead allelic frequencies for several isozymes gradually change in a north to south pattern in populations along the Oregon coast. . . . Small basin populations were shown to have some distinct differences from the large basin populations. While the cause of the differences is not known, the effects of genetic drift on these small, relatively isolated populations is suggested.” (p.42) Major professor was Hiram W. Li.

Note that these were the coastal peoples - for example, the Upper Umpqua and Upper Coquille peoples were Athapaskans, with a different cultural heritage."The most important resource of the area was salmon, which were taken from canoes in deep water, dipnetted, harpooned, clubbed, and trapped at upriver weirs or in rapids and shallow water. Additionally, the estuaries and rivers supported major runs of herring, smelt, lampreys, and less seasonally limited supplies of various saltwater and freshwater fish."

Benthic Invertebrates at a Test Dredged-Materials Disposal Site in the Umpqua River, Oregon - Miller, David R.; Emmett, Robert L.; McConnell, Robert J. (Coastal Zone and Estuarine Studies Division, Northwest Fisheries Center, 1989)
The Umpqua River was dredged in September, 1987 at the entrance of Winchester Bay. NMFS investigated the materials disposal site to assess the impact of disposal on benthic fauna. Sediments were sampled before and after dredging. The Umpqua showed high species diversity at low density (122 different invertebrate taxa) before dredging, and even higher diversity with higher density after dredging (144 taxa). The authors discuss possible reasons for the surprising increase in benthic invertebrates following this dredging.

Ecology and Decline of a Rare Western Minnow: The Oregon Chub (Oregonichthys crameri) - Pearsons, Todd N. (Oregon State University, 1989)
The Oregon chub is presently found only in the Umpqua and Willamette drainages. This rare fish seems to be in decline. This study attempts to describe life history, habitat requirements, reproduction, and diet of the Oregon chub. One factor in its decline seems to be its need for slowly moving or slack water as a habitat. The related Umpqua chub can survive in faster-moving waters and is doing better. Methods of identifying larvae are given. The major professors for this Masters thesis were Hiram W. Li and Douglas F. Markle.

An Evaluation of the Effectiveness of Instream Structures for Steelhead Trout Rearing Habitat in the Steamboat Creek Basin - Fontaine, Barbara L. (Oregon State University, 1987)
In 1985-1986, different types of instream structures designed to improve habitat for steelhead trout (boulder clusters, boulder-log clusters, angle logs, blast pools, single boulders, boulder pairs, and interstitial blasting) were built in streams in the Steamboat Creek Basin and subsequently evaluated. Treatments were deemed ineffective. "The treatment that had a statistically significant effect (blast pools) on the summer standing crop of juvenile steelhead only increased the 1+ population by a few individuals. . . Habitat preservation is undoubtedly the most cost effective option." (p.49) There was a learning curve, and the author learned how to build more effective structures over the course of the study. Also, she gained a better understanding of the different seasonal needs (summer / winter) of juvenile steelhead trout. The author urges that enhancement programs be followed by evaluations of their effectiveness. The major professor was James D. Hall.

Nest locations and nesting habitat of the marbled murrelet (Brachyramphus mamoratus) in coastal Oregon - Varoujean, Daniel H.; Williams, Wendy A. (Technical Report / Oregon Department of Fish and Wildlife, Nongame Wildlife Program, 1987)
A research project was carried out over two study periods (March-September 1986, March-August 1987) to determine the nest locations and nesting habitat of marbled murrelets (Brachyramehus marmoratus) in coastal Oregon . . . A suspected nesting area was found through the identification of calling murrelets at Remmy Creek, a forested basin in Douglas County located 44 km from the ocean. This 260 ha basin contains stands of old-growth conifers, principally Douglas-fir (Pseudotsuga menziesii), and is estimated to support three to five pairs of nesting marbled murrelets. Abundance surveys indicate that at-sea murrelet abundance in the study area is patchy, in that it declines with increasing distance from the mouths of rivers and bays, and varies from day to day in the same area. Based on murrelet density estimates in the study area, the breeding population of marbled murrelets in coastal Oregon is tentatively estimated to be approximately 2,500 pairs of birds. (p.1)

Food Habits and Dietary Adaptation of the English Sole (Parophrys vetulus) in a Recently Disturbed Habitat - Marks, Dennis Keith (Dept. of Biology, 1986)
This Master’s thesis examines the changes in diet of English sole in an area affected by the construction of a jetty. In 1980, the training jetty in the Umpqua River entrance was extended to control cross-currents. Before construction, the area was dynamic and strongly affected by riverine flows. After the jetty was built, the area had much less wave action, had more sedimentation, and salinity was much higher. As the environment changed, did the diet of English soles change? The author examined sole stomach contents over the period of 1980-1982 to find out. “Excepting amphipods and nematodes, which were largely absent probably because of their small size, all invertebrate taxa were represented in the sole stomachs in roughly the same proportions as observed in the changing sediment samples, demonstrating a low degree of food selectivity and a corresponding high capacity for dietary adaptation.” (from the Abstract)

The Relative Effects of Ceratomyxa shasta on Crosses of Resistant and Susceptible Stocks of Summer Steelhead - Wade, Mark (Oregon State University, 1986)
In 1971, after a new fishway was built at Willamette Falls, ODFW introduced summer steelhead into the Upper Willamette River, from stocks from the Siletz and Skamania rivers. The Skamania fish returned, but the steelhead that originated from Siletz River stock did not, due to infection by a myxosporean parasite, Ceratomyxa shasta. Subeequent testing for resistance to infection showed that the Siletz and Umpqua River stocks are susceptible to this infection. This thesis shows that even disease-resistant stocks can have their resistance weakened by interbreeding with less-resistant strains, a potentially dangerous side-effect of hatcheries. The major professor was Hiram Li.

The Skamania fish returned, but the steelhead that originated from Siletz River stock did not, due to infection by a myxosporean parasite, Ceratomyxa shasta. Subeequent testing for resistance to infection showed that the Siletz and Umpqua River stocks are susceptible to this infection. This work (essentially, the author's M.S. thesis) shows that even disease-resistant stocks can have their resistance weakened by interbreeding with less-resistant strains, a potentially dangerous side-effect of hatcheries.

Disposal of Seafood Waste to Enhance Recreational Fisheries on the Umpqua River Estuary - Miller, B. A. (Fish Division, Oregon Dept. of Fish and Wildlife, 1984)
ODFW Progress Reports. In 1981, the Douglas County Dept. of Public Works banned dumping of seafood processing waste in the county landfill. The processing plants began negotiations to discharge their wastes into the Umpqua Estuary. This study, began in Sept. 1982, was intended to learn what happened to discharged wastes, their impact on water quality and the estuary's life, see if seafood wastes could enhance production of fish and shellfish, and set criteria for locating and timing waste disposal into the bay. Maps. Includes list of species seined between Cornwall Point and Salmon Harbor west basin entrance.

Interaction and Behavior of the Redside Shiner (Richardsonius balteatus) and the Steelhead Trout (Salmo gairdneri) in Western Oregon: the Influence of Water Temperature - Reeves, Gordon H. (Oregon State University, 1984)
This dissertation looks at competition between two different species of freshwater fish, the redside shiner, and the steelhead trout. Water temperatures influenced fish behavior and helped determine which species was dominant in warmer or cooler waters. The social behavior and adaptive strategies of the two species are considered. The major professor was James D. Hall.
