  Citation × Citation Citation Abstract Copy Title: Oregon Fish Passage Barriers Abstract -- The Oregon Fish Passage Barrier Data Standard (OFPBDS) dataset contains barriers to fish passage in Oregon watercourses. Barriers include the following types of natural or artificial structures: bridges, cascades, culverts, dams, debris jams, fords, natural falls, tide gates, and weirs. The OFPBDS dataset does not include structures which are not associated with in-stream features (such as dikes, levees or berms). Barriers are structures which do, or potentially may, impede fish movement and migration. Barriers can be known to cause complete or partial blockage to fish passage, or they can be completely passable, or they may have an unknown passage status. This dataset complies with version 1.1 of the OFBPDS data standard. New optional attributes have been added to describe fish passage barrier feature modifications, to describe supplementary information (via a comments field) and also to linear reference the barrier features to the National Hydrography Dataset. The OFPBDS dataset now contains over 40,000 barrier features from 19 separate sources including: Oregon Department of Fish and Wildlife (ODFW), Oregon Department of Transportation (ODOT), Oregon Department of Water Resources (OWRD), Oregon Department of Forestry (ODF), Oregon Watershed Enhancement Board (OWEB), Oregon Department of Land Conservation and Development (DLCD) US Bureau of Land Management (BLM), US Forest Service, Nez Perce Tribe, Benton SWCD, Washington county, Lower Columbia River Estuary Partnership and watershed councils representing the Rogue, Umpqua, Siuslaw, Santiam, Calapooia, Clackamas and Scapoose basins. The Data Steward obtained fish passage barrier data from multiple data originators between 2008 and 2015, collaborated with them to develop inclusion / exclusion criteria and dataset specific crosswalks for converting data from its original data structure to the structure of the OFPBDS. The data were then converted into the OFPBDS format and analyzed for duplication with existing OFPBDS barrier features. Where duplicates were identified, depending upon the scenario, one feature was either chosen over the other or in some cases attributes from different sources are combined. Source information is retained for each feature. The data were then loaded into the OFPBDS database. Barrier features were linear referenced (Framework Hydro only which is outside of the standard) and the corresponding optional attribute elements were populated. The data conversion, duplication reconciliation and linear referencing protocols are documented in the Oregon Fish Passage Barrier Data Management Plan. A separate dataset containing fish passage barrier features that have been completely removed or replaced (e.g. dam removals and culvert replacements) is published simultaneously with the OFPBDS dataset. The OFPBDS database is the most comprehensive compilation of fish passage barrier information in Oregon however, it does NOT represent a complete and current record of every fish passage barrier within the state. Efforts to address deficiencies in data currency, completeness and accuracy are ongoing and are often limited by lack of sufficient resources. Attributes (including key attributes such as fish passage status) are often unknown or incomplete. Consistency in attribution also varies among data originators. Field verification of barrier features and their attributes will be an important component to making this dataset current, comprehensive and accurate. Fish passage status is a key attribute. Many barrier features have an unknown passage status. For other features, the passage status may have changed since it was originally documented. Note that this metadata file is best viewed in ArcCatalog. Documentation for the OFPBDS can be found online at http://www.oregon.gov/DAS/EISPD/GEO/docs/bioscience/OregonFishPassageBarrierDataStandardv1dot1.pdf.

  Citation × Citation Citation Abstract Copy Title: Lower Umpqua Watershed Analysis, 1997 Abstract -- This analysis of the Lower Umpqua River watershed (2% of the total Umpqua River drainage area) in the southern Coast Range includes watershed characterization, issues, inherent landscape instability, aquatic species' habitat and population, terrestrial species' habitat and population, and restoration opportunities. This analysis was conducted by Siuslaw National Forest personnel with assistance from the Bureau of Land Management - Coos Bay District. The analysis was focused on fisheries and wildlife issues. The existing resource conditions were compared to expected natural conditions to assess trends in resource conditions. From this information, a strategy of restoration opportunities to enhance resource conditions on federal lands was developed. Watershed Analysis is one of the key components of the Aquatic Conservation Strategy (ACS) developed for the Northwest Forest Plan (NFP) (USDA-USDI 1994). The analysis is intended to facilitate watershed planning that: 1) achieves Aquatic Conservation Strategy and Late-Successional Reserve objectives and 2) provides the basis for monitoring and restoration programs.

  Citation × Citation Citation Abstract Copy Title: Status of Winter Rearing Habitat in Four Coho Population Units_ODFW AQI Winter Report Final 2008 Abstract -- We described the status of habitat in four Oregon coastal coho salmon (Oncorhynchus kisutch) population units (Nehalem, Siuslaw, Coquille, South Umpqua) during winter 2007, estimated the potential winter rearing capacity of streams within those population units, and described the differences observed in stream habitat between winter and summer with emphasis on slow water and secondary channel habitats. Sample sites were randomly selected and spatially balanced within the distribution of coho salmon (juvenile and adult) in Oregon coastal watersheds south of the Columbia River. Twenty five sites were targeted within each of the four population units. Each survey was approximately 1000 m in length and adhered to protocols in Moore et al (2007). The Habitat Limiting Factors Model (HLFM) was used to estimate habitat capacity and quality for rearing juvenile coho. The HLFM predicted that the Nehalem and Siuslaw basins could support the highest density of juvenile coho, and the South Umpqua the least. Seasonal changes in habitat were similar to that reported in a previous study. Winter surveys facilitated the assessment of habitat status and estimating capacity because the surveys were conducted at the time when habitat is most limiting to survival of juvenile coho. Winter surveys were particularly valuable in capturing secondary channel and slow water habitat units such as beaver ponds and alcoves. We also performed a sensitivity analysis to determine the number of survey sites necessary to represent each population unit within the desired confidence range of 30% recommended in the Coho Conservation Plan. Twenty five target sites were not adequate to describe the winter parr capacity within a 95% confidence interval of +30% in each population unit. Confidence intervals of estimates of parr per km ranged from 34 to 60% and mean parr per m2 ranged from 20 to 45%.

The Coos Watershed Association (CoosWA), funded by two grants from the Oregon Watershed Enhancement Board (OWEB), the Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians (CTCLUSI), and Weyerhaeuser Company evaluated 793 km of the 853 km road system surrounding the East Fork Millicoma River. We used the Geomorphic Road Analysis and Inventory Package (GRAIP), designed by the U.S. Forest Service, which evaluates surface erosion, gully risk, landslide risk and stream crossing failure risks. Additionally, CoosWA surveyors recorded information on road features to develop a database to be used for long-term-road asset management.

  Citation × Citation Citation Abstract Copy Title: Using Calibrated Index Surveys to Estimate Chinook Spawner Escapement into the Salmon River, Oregon Information Report number 2012-01 Abstract -- The Pacific Salmon Commission has designated the Salmon River hatchery stock of fall Chinook as an Exploitation Rate Indicator Stock (ERIS) for all 16 naturally produced stocks of fall Chinook on Oregon’s north coast. The Pacific Salmon Treaty (PST) specifies the necessity of these stocks to model the effects of mixed stock fisheries on wild Chinook salmon. The ocean migration patterns and catch rates of this stock are thought to closely resemble Oregon’s north migrating Chinook from coastal basins ranging from the Necanicum River in the north to the Siuslaw River in the south. A relatively long and continuous history of mark and recapture experiments with corresponding extensive spawning ground surveys and harvest estimates from a fresh water creel, serves as the foundation for a predictive model of spawner abundance. Peak counts from two spawning ground surveys were identified as an index that strongly correlates with relatively precise abundance estimates derived from a Peterson two event mark-recapture model. Index surveys are less labor intensive than previous mark-recapture activities, and evidence suggests they are an efficient and cost effective method to estimate spawner abundance.

  Citation × Citation Citation Abstract Copy Title: Mid-Coast Small Ocean Tributary Streams Fish Management Plan 1997 Abstract -- The Fish Management Policy of the Oregon Department of Fish and Wildlife (ODFW) requires that management plans be prepared for each basin or management unit. The MidCoast Small Ocean Tributary Streams Fish Management Plan (hereafter referred to as the Ocean Tributaries Plan) was developed to direct management of the fish resources of Beaver Creek, Cummins Creek, Bob Creek, Tenmile Creek, Rock Creek, Big Creek, Cape Creek, and all other mid-coast small ocean tributary streams except those systems containing lakes or reservoirs. The Ocean Tributaries Plan is one of several Oregon mid-coast basin plans developed by ODFW. Other plans have been developed for the Salmon River, Siletz River, Yaquina River, Alsea River, Yachats River and Siuslaw River basins. ODFW is committed to the planning process as an integral part of all current and future management by the agency. Species plans for coho, coastal chinook, steelhead, trout and warmwater game fish have been adopted. These statewide plans guide the development of more localized plans for individual river basins and sub-basins.
