During autumn 2009 and winter 2010, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE), conducted a hydrographic survey using a multibeam echosounder system (MBES). The survey was from river mile (RM) 130 to 142 on the Snake River, and from RM 0 to 2 on the Clearwater River areas of Lower Granite Reservoir. The survey mapped the part of the river that was accessible to the boat and the echosounder equipment, but very shallow areas along the banks that were inaccessible or too shallow to be measured with echosounder equipment were not mapped. The survey was conducted in 1-mile segments, and the data were combined to provide a continuous digital elevation dataset of the...

The first of six strategies in Canada’s Policy for the Conservation of Wild Pacific Salmon concerns the identification of units of diversity (called Conservation Units) and determining their conservation status. The primary purpose of this document is to describe the method that was developed to identify the Conservation Units for the five species of Pacific salmon in British Columbia. The description of units in most of the Yukon and Northwest Territories will proceed using this method once the ecotypology of those areas is completed.The approach of Waples et al. (2005, Journal of Fish Biology, volume 59, pages 1-41) was modified to characterize diversity in Pacific salmon along three major axes: ecology, life...

Overall Rank RAP Watersheds The Riverscape Analysis Project (RAP) is a web-based GIS Decision Support System that was designed to assist in salmon conservation across North Pacific Rim (NPR) Rivers. RAP is based upon a robust classification (typology) of rivers and river habitats which is aimed at mapping habitat quality and abundance, as well as conserving the existing potential production of salmon and the rivers that they spawn and rear in. Key elements of the RAP system include relative habitat rankings, GIS tools to extract and download data, a subset of high resolution remote sensing imagery, and models of salmon habitat suitability based on current and future climate scenarios.

Understanding how routing modifications influence survival of juvenile salmon is complex because reach-specific survival and routing at key river junctions in the North Delta each have a different relationship with river flow. Therefore, to facilitate understanding of how routing modifications at key river junctions influence through-Delta survival, we developed this spreadsheet model to allow managers to explore the potential effects of modifying routing. The purpose is to provide a screening tool that allows managers to quickly run many different scenarios to understand how both routing and route-specific survival interact to affect overall survival through the Delta. This tool may be useful in narrowing the range...

This dataset contains the 2012 version of the anadromous fish streams (polylines) for Southeast Alaska and is pull from the Anadromous Waters Catalog. The Alaska Department of Fish and Game's (ADF&G) Anadromous water bodies data is derived from the ADF&G's GIS shape files for the "Catalog of Waters Important for Spawning, Rearing or Migration of Anadromous Fishes" (referred to as the "Catalog") and the "Atlas to the Catalog of Waters Important for Spawning, Rearing or Migration of Anadromous Fishes" (referred to as the "Atlas"). It is produced for general visual reference and to aid users in generating various natural resource analyses and products. The shape files depict the known anadromous fish bearing lakes...

This dataset includes the boundaries evolutionarily significant units (ESUs) of salmon on the West Coast of the United States of America. An evolutionarily significant unit, or ESU, of Pacific salmon is considered to be a "distinct population segment" and thus a "species" under the Endangered Species Act. Chinook salmon, Chum salmon, Coho salmon, Pink salmon, Sockeye salmon, and steelhead are all included in the dataset. ESU boundaries were compiled by the GIS group at the Bonneville Power Administration from various sources based on written descriptions in NOAA Fisheries Service status reviews (available upon request) and mapping provided by the Fisheries Service. Initial boundaries were derived from USGS 1:250,000...

This dataset is used for cartographic representation of "double-line" streams where braided watercourses, wide channels and multi-channels occur on stream/river systems. This particular version of the dataset was developed to submit to the National Hydrography Dataset (NHD) As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this metadata for an older version of the source data. This dataset provides cartographic representation of "wide" linear water features of the Tongass National Forest in Southeast Alaska with the inclusion of some features from state and private lands.

Field measurements of saturated hydraulic conductivity were used to characterize the streambed permeability for two reaches of the lower Merced River in California's Central Valley to support research intended to evaluate the extent to which large-scale restoration projects provided improved salmon spawning habitat. A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. Saturated hydraulic conductivity, denoted by K, was measured with a backpack permeameter and modified Mark VI groundwater standpipe using the constant head method of Terhune [1958]. For each reach, permeameter measurements were collected at ten sites spanning a single...

Native fish of the Columbia River Basin, and the ecosystems that support them, are an innate and critical part of Nez Perce culture. The persistence of these fisheries may be at risk due to climate change, especially in combination with other stressors (e.g., habitat fragmentation and disconnectivity). Assessing vulnerability of these fisheries to climate change, considering options for action, and taking action will require strategic collaboration and coordination with multiple partners. Here, we propose to start building those partnerships to address this landscape-level conservation concern.The overarching philosophy of Nez Perce fisheries management is to ensure that all species and populations of anadromous...

Here we describe one conservation tool that will help to identify particularly significant river basins of the North Pacific for the conservation of salmon: the first Pacific-Rim wide assessment of salmon populations at a consistent scale. In conjunction with a scientific advisory panel and a peer review workshop we developed four criteria for the Pacific Salmon Conservation Assessment (PSCA) to provide an indication of aquatic ecosystem and salmon population resilience at the basin scale. These criteria are salmon abundance, diversity, hatchery influence, and landscape suitability. Highly abundant salmon populations have more “cushion” with which to absorb anthropogenic or natural disturbance (Quigley and...

We used snorkel surveys in the Elwha River, conducted in consecutive years before (2007, 2008) and after (2018, 2019) dam removal to assess changes in fish distribution and density. In total, we counted 54,616 Chinook Salmon, Bull Trout, Steelhead, and trout (Rainbow Trout and Coastal Cutthroat Trout combined) in 22 common reaches spanning 65 river kilometers. The occupancy of juvenile Chinook Salmon, Coho Salmon, and trout was also assessed following dam removal.

Field measurements of water depth were acquired from a reach of the upper American River in California, November 5-7, 2018, to support research on mapping chinook salmon spawning locations (redds) via remote sensing. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor S5 acoustic Doppler current profiler (ADCP) deployed...
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

This data release includes images and field measurements used to map chinook salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely sensed data. Traditionally, redds have been mapped by eye while walking the bank or from a boat, or by an observer in an aircraft or an interpreter visually examining aerial images. The goal of this proof-of-concept investigation was to assess the potential for more efficient, objective, and automated redd mapping from conventional...
