  Citation × Citation Citation Abstract Copy Title: Clear and Foster Creek Watershed Assessment Abstract -- A watershed assessment was completed in the Clear and Foster Creek watersheds to evaluate existing conditions and make recommendations to protect or enhance watershed natural resources. Clear and Foster Creek are tributaries to the Clackamas River below any major dams on the system; consequently these tributaries are positioned favorably to contribute to recovery of important anadromous fish populations. Anadromous fish species in the Clackamas basin include spring and fall chinook, coho salmon, winter steelhead, summer steelhead (non-native), migratory cutthroat trout and lamprey. Clear and Foster Creeks are utilized by fall chinook, winter steelhead and coho salmon. The assessment generally followed the framework described in the Oregon Watershed Enhancement Board’s Watershed Assessment Manual (WPN, 1999). The assessment focused on the following components: Channel habitat classification and modification; hydrology and water use; riparian/wetlands; sediment sources; water quality; fisheries; and wildlife and upland vegetation. Generally the approach builds on existing information, and enhances this information with aerial photo interpretation and limited field checking. Additional fieldwork was used to verify channel habitat types and to characterize fish habitat condition. GIS was used as a critical assessment tool and method of displaying results.

The basis of these estimates are visual counts of adult spawners in randomly selected stream reaches. To date, survey-derived estimates have not been validated against known spawner abundances. Beginning in 1999, we initiated a study at Smith River (Umpqua Basin) to calibrate survey-based spawner estimates. Smith River provides an ideal location for this type of study because it is typical of many other coastal streams that support coho salmon, contains large quantities of habitat and spawners, and provides the ability to efficiently trap and tag adequate portions of the coho run.

  Citation × Citation Citation Abstract Copy Title: OASIS - Lower Columbia River Coho Status Report 2002 – 2004: Population abundance, distribution, run timing, and hatchery influence. Abstract -- This report provides an assessment of abundance, distribution, spawn timing, and hatchery:wild ratios of spawning adult coho salmon (Oncorhynchus kisutch) based on EMAP spawning surveys in the Oregon portion of the Lower Columbia River in the 2002, 2003, and 2004 spawning seasons. The Oregon portion of the Lower Columbia River Evolutionarily Significant Unit (ESU) extends from the mouth of the Columbia River to the Hood River, excluding areas above Willamette Falls. Analysis is conducted at the population complex level, six subsets of the ESU defined during Oregon Department of Fish and Wildlife Status Review (Chilcote 1999). Population characteristics, most notably the proportion of wild spawners and spawn timing, vary among complexes. Interannual variation within complexes over the last three years is linked to streamflow variation. Most hatchery straying occurred within complex, though the Bonneville complex received strays from further upriver. Abundance increased in areas without evidence of hatchery inputs. Abundance goals established by the ODFW endangered species management plan (Chilcote 2001) in the Clackamas (>1900 adults) and Sandy (>670 adults) have been met the last two years; however, spawner densities and the proportion of wild spawners are lower than on the Oregon Coast.

  Citation × Citation Citation Abstract Copy Title: Oregon Fish Habitat Distribution - Pacific Lamprey Abstract -- The Pacific lamprey has inhabited the rivers, streams and coastal waters of the west for 350 million years (BPA, 2005). These data describe areas of suitable habitat currently and historically used by Pacific lamprey populations. Pacific lamprey, Lampetra tridentata, (more recently identified as Entosphenus tridentatus), are native to the Pacific coast from Baja California to the Bering Sea. They are anadromous, migrating from their natal stream to the ocean and back, but unlike salmon, Pacific lamprey spend well over half of their total life cycle in freshwater. The Pacific lamprey was listed as an Oregon State sensitive species in 1993 and in 1996 was protected through restriction of harvest (ODFW 2006). These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in February 2011. The Standard document can be found at: http://gis.oregon.gov/DAS/EISPD/GEO/standards/docs/OregonFishHabitatDistributionDataStandardv2.pdf The term "currently" is defined as within the past five reproductive cycles. This information is based on sampling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually.Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the Pacific Northwest Framework Hydrography dataset. The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1990 to 2011. Data were migrated to the NHD in Spring of 2014.

These activities are coordinated under the Oregon Plan for Salmon and Watersheds and are part of a broader effort to monitor populations of salmonids in select Oregon coastal streams. Two objectives of this program are to estimate the abundance of returning adult salmonids and downstream-migrating juvenile salmonids, and estimate the marine and freshwater survival rates for coho salmon. This record provided catch summary reports from monitoring activities for the 2005-2006 run-year of returning adult fish and year 2006 out-migration of juvenile fish in the West Fork Smith River.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2012 Annual Report Abstract -- In the Willamette Basin upstream of Willamette Falls (Figure 1), there are four distinct spring Chinook salmon hatchery programs (North Santiam [Stock 21], South Santiam [Stock 24], McKenzie [Stock 23], and Middle Fork Willamette [Stock 22]) that are managed for integrated harvest augmentation as part of the Willamette Valley Hatchery Mitigation Program. These hatchery stocks, as well as all naturally spawned spring Chinook salmon in the Upper Willamette Basin, are included in the Upper Willamette River Evolutionary Significant Unit (ESU). The Upper Willamette Summer Steelhead Hatchery Program is managed to provide fish for sport fisheries and to replace loss of fisheries caused by habitat and passage loss/degradation in the Willamette Basin and other lower Columbia basins. The hatchery program currently includes annual smolt releases into the North Santiam, South Santiam, McKenzie, and Middle Fork Willamette rivers. Lack of access to historical habitat and degradation of remaining habitat below the dams, especially in the North and South Santiam (the “core” populations) are the key limiting factors shared between winter steelhead and spring Chinook salmon. In addition, summer steelhead are not native to the Willamette Basin upstream of Willamette Falls and a third, unique, limiting factor is the potential for competition, predation and genetic introgression from out-of-ESU hatchery fish interacting with and spawning in the wild with the native winter-run. Summer steelhead were first introduced to the South Santiam River as mitigation for lost winter steelhead production in areas inundated by Foster and Green Peter reservoirs. The scope of work actually directed towards risks posed by summer steelhead is much smaller than that directed towards issues faced by spring Chinook. The Willamette Project Biological Opinion (BiOP; NMFS 2008) required the USACE to collect information to describe the nature and extent of these potential effects but beyond relatively small-scale studies often integrated into much larger studies involving spring Chinook, more focused work will only follow commitment of significantly more effort and funds. 11 This report fulfills a requirement under Task Order NWPPM-10-FH-06, covering activities of May 2012–June 2012, that were implemented by ODFW on behalf of the Corps to assist with meeting requirements of the reasonable and prudent alternatives (RPAs) and measures prescribed in the Willamette Project Biological Opinion (BiOp) of July 2008 (NOAA 2008).

Hatchery practices have in many cases served to advance our knowledge of both hatchery and natural production spring Chinook populations, although improvements could be made with respect to data collection, management and analysis. Nevertheless, UWR hatcheries have either been directly involved with or provided support to numerous research efforts that have generated data on adult spring Chinook run sizes, spatial distributions, stock structures, straying rates, production, survivorship, juvenile outmigration, ocean distribution and harvest. We have summarized these data in this report. Our review has also identified numerous critical uncertainties and information gaps related to UWR spring Chinook hatchery programs. We have identified these points through the review of existing data, and developed an exercise to relate these data to previously identified information needs (Chapter 4). Based on our analyses and identification of critical uncertainties, we developed recommendations (Chapter 5) intended to improve the focus and management of UWR spring Chinook hatcheries through research, management and evaluation (RM&E) efforts.

  Citation × Citation Citation Abstract Copy Title: Willamette BiOp - Genetic Stock Identification and Relative Natural Production of Willamette River Steelhead Abstract -- We used genotypic data from 15 microsatellite loci to characterize the stock structure of Oncorhynchus mykiss in the upper Willamette River basin. We then used two analytical approaches, implemented in the programs ONCOR and STRUCTURE, to assign (presumably) natural-origin, unmarked fish to their most likely reporting group or hybrid class. We investigated sibling relationships among unknown samples with the program ML RELATE. In the upper Willamette River, O. mykiss genetic structure can be characterized by four principal groups: summer steelhead of Skamania stock ancestry, eastern tributaries winter steelhead, western tributaries winter steelhead and resident rainbow trout. We found that about 10% of unmarked juvenile O. mykiss sampled at Willamette Falls in 2009-2011 were summer steelhead and that an additional 10% of samples were summer x winter steelhead hybrids. Most O. mykiss sampled from the McKenzie River were either summer steelhead or summer x winter steelhead hybrids. Natural production of pure summer steelhead appeared to be very low in the North and South Santiam rivers, though summer steelhead hybrids represented 11.1% and 14.8% of samples. Results from ML RELATE analyses appeared unreliable and inconclusive, and may have been limited by low genetic diversity among summer steelhead samples. We provide several recommendations to better understand and reduce potentially negative interactions between hatchery summer steelhead and native upper Willamette River O. mykiss populations. These include reductions in adult steelhead on natural spawning grounds, improved reproductive isolation between hatchery and native populations and additional research to evaluate genetic integrity within and among O. mykiss populations.

In the upper Willamette River, O. mykiss genetic structure can be characterized by four principal groups: summer steelhead of Skamania stock ancestry, eastern tributaries winter steelhead, western tributaries winter steelhead and resident rainbow trout. We found that about 10% of unmarked juvenile O. mykiss sampled at Willamette Falls in 2009-2011 were summer steelhead and that an additional 10% of samples were summer x winter steelhead hybrids. Most O. mykiss sampled from the McKenzie River were either summer steelhead or summer x winter steelhead hybrids. Natural production of pure summer steelhead appeared to be very low in the North and South Santiam rivers, though summer steelhead hybrids represented 11.1% and 14.8% of samples. Results from ML RELATE analyses appeared unreliable and inconclusive, and may have been limited by low genetic diversity among summer steelhead samples. We provide several recommendations to better understand and reduce potentially negative interactions between hatchery summer steelhead and native upper Willamette River O. mykiss populations. These include reductions in adult steelhead on natural spawning grounds, improved reproductive isolation between hatchery and native populations and additional research to evaluate genetic integrity within and among O. mykiss populations.

These ongoing monitoring programs provide technical, logistical, and biological information to managers charged with maintaining viable salmon and steelhead populations and associated fisheries in Northeast Oregon. This report is organized into fish culture monitoring for juveniles, adults, CWT recoveries, and estimates for total escapement. During the period covered in this report, steelhead from the 1999-2001 broods returned to spawn, and steelhead from the 2003 brood were released as smolts. Adult steelhead that returned to spawn were used to create the 2004 brood. Corrections: Complete code wire tag (CWT) information from the Warm Springs National Fish Hatchery and the Washington Department of Fish and Wildlife was not available when the 2003 report was published. We have updated tables 10 through 12 of the 2003 Annual Progress Report, which present summaries of CWT recovery estimates for the 2002-2003 run year, to reflect this new information. Updated tables are in the addendum. All changes are in bold.

These surveys represent the fourth year of the US/Canada Pacific Salmon Treaty Monitoring Program implemented in 1986 by tribal, state and federal fishery agencies. The Pacific Salmon Treaty directs fishery management entities to conserve and rebuild chinook salmon stocks originating from the Columbia River Basin by appropriate ocean and in-river harvest controls. In order to monitor the success of the Pacific Salmon Treaty, annual spawner escapement of chinook salmon "indicator" stocks must be determined. The spring chinook salmon stocks of the John Day, Grande Ronde, and Imnaha River basins have been identified as potential indicator stocks for monitoring. These drainages were selected because of the unique wild salmon chinook stock in John Day River and wild stock component of spring chinook runs in the Grande Ronde and Imnaha Rivers. In addition, base line data have been established because ODFW has conducted spring chinook salmon spawning ground surveys in these basins since 1960. The comprehensive and multiple index surveys completed in 1989 were developed to collect information which could provide an estimate of spawner escapement and be comparable to historic redd survey data. In addition to spawning ground surveys, a new method was implemented to estimate spawning escapement. In 1989, snorkel and foot surveys were conducted in the Middle Fork John Day River to enumerate spring chinook salmon holding prior to spawning. The Middle Fork of John Day River was selected as the study site because 1) the holding and spawning area is only 30 miles long (the entire 30 miles could be sampled within one week) 2) the 30 mile section has good access by road and 3) the 30 mile section is generally narrow and shallow. Snorkeling and foot surveys were chosen as the method because 1) there are no weirs on the John Day River to count fish 2) snorkeling is a low-impact method and 3) other studies have shown snorkeling to be both time and cost effective with good success for estimating fish population size (Northcote and Wilkie (1963); Zubik and Frayley (1988)).
