For the past six years, the Bureau of Reclamation (BOR) has funded the USGS to study fish responses to restoration efforts and to construct a model relating stream habitat with fish population dynamics in the Methow River Basin, a tributary of the Columbia River. In the proposed study, we will use fish growth, distribution and movement (USGS data), foodweb data (Idaho State University), river flow (BOR data that we will expand) and water temperature data (from numerous agencies) to develop spatially-explicit bioenergetics models to assess effects of climate change on the viability of resident salmonid populations based on models being developed by USGS. The bioenergetics models will integrate such things as climate-change...

The Cascadia Partner Forum will complete conservation design for four Great Northern Landscape Conservation Cooperative conservation targets with significance to the transboundary Cascadia landscape to inform sound, data-driven management planning and action. This project aims to complete conservation design at the Cascadia-wide scale for grizzly bear, salmon, aquatic, and terrestrial connectivity to contribute to the Great Northern LCC Science Plan, while providing input and integration to the coarser-scale GNLCC-wide Science Plans established objectives, threats, metrics, and conservation actions for each target. Additionally, the Forum will conduct analyses on a common Great Northern LCC landscape stressor roads...

The Great Northern Landscape Conservation Cooperative (GLNCC) has convened the Columbia Basin Partner Forum (CBPF) to help facilitate collaboration among conservation practitioners and partnerships that share landscape conservation challenges in an eco-geographic context. Through a loosely structured process, field-level managers, scientists, and conservation constituents will identify priority conservation information, scientific needs, and implementation opportunities within the scope of the Great Northern LCC Strategic Conservation Framework. The CBPF will also provide a means to engage the partnership network (a more diverse and directly knowledgeable constituency) on specific conservation needs that will inform...

Climate change, drought, habitat alterations, and increasing water demands are leaving less water available for streams of the Pacific Northwest and for fish like salmon. As water levels drop, some small streams become fragmented, transforming from a ribbon of continuous habitat into a series of isolated pools. Fragmented streams may pose a serious threat to salmon. For example, juveniles that become stranded in small pools are at increased risk to overheat, starve, or be consumed by predators. Healthy salmon populations can cope with fragmentation and recover from a bad drought-year. However, many salmon populations are endangered and face long-term drought. Land and resource managers are increasingly finding...

The data contain yearly modeled estimates of Pacific salmon escapement (in annual metric tons of wet mass) from 1976 to 2015 across four regions of western North America. A second data file contains modeled estimates of contaminant or nutrient concentrations in Pacific Salmon. The modeled estimates were derived from Bayesian generalized linear models (contaminant or nutrient concentrations) or from Bayesian generalized additive models (Salmon Escapement).

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...
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...
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...

Existing stream temperature data were compiled from numerous federal, state, tribal, and private sources to develop an integrated regional database. Spatial statistical models for river networks were applied to these data to develop an accurate model that predicts stream temperature for all fish-bearing streams in the US portion of the GNLCC. Differences between model outputs for historic and future climate scenarios were used to assess spatial variation in the vulnerability of sensitive fish species across the GNLCC.FY2011Objectives: Develop a regional stream temperature model that incorporates important climate drivers, wildfire/riparian conditions, and geomorphic factors; Use the model to understand and predict...

The goal of this study is to use eDNA as a cost effective tool for documenting the occurrence and distribution of ESA-listed spring-chinook (Oncorhynchus tshawytscha) throughout the Okanogan and Methow watersheds in an effort to map habitat use and connectivity. Our approach will use eDNA to detect low density spring-chinook in filtered water samples to inventory distribution and re-colonization of tributaries at strategically-sampled points throughout entire stream networks. This approach will provide one of the first applications of eDNA technology for monitoring distribution of native fish species of conservation concern. The findings will help the Colville Tribe Fisheries Managers assess aquatic connectivity...
