Forecasting the impacts of Climate Change in the Columbia River Basin: Threats to Fish Habitat Connectivity
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...
Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. USGS scientists worked closely with state management agencies and the National Wildlife Federation to complete several objectives that provide knowledge to aid their planning and management strategies in anticipation of coming changes. First, researchers updated a regional Great Lakes climate model to predict water level changes, water temperatures, and ice cover data for the entire Great Lakes basin 50-100 years into the future. Second, researchers used satellite data to determine whether the...
The NorWeST Regional Stream Temperature Model for Mapping Thermal Habitats and Predicting Vulnerability of Aquatic Species to Climate Change Across the Great Northern LCC
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...
