Description

Climate change is warming aquatic ecosystems and will have profound consequences. Effective conservation of aquatic resources will require unprecedented levels of interagency coordination.  In addition, it will require the development of datasets and models for accurate downscaling of climate change effects to important habitat parameters and species distributions at local scales. Many broad-scale bioclimatic assessments have been done for salmon and trout in the Rocky Mountains, but most rely on air temperature or elevation- imprecise surrogates for stream temperature.  This project generates stream temperature data rather than relying on air temperature or elevation surrogates.

Key Points:

  • The NorWeST database may be the largest of its kind, consisting of stream temperature data contributed by over 60 state, federal, tribal, and private resource agencies across the western United States.
  • The data contained in NorWeST would require $10,000,000 to replicate, but the information these data yield for decision making and prioritizing future investments has value that is much greater.
  • Temperature data, model outputs, and metadata are posted to the NorWeST website available to download as ArcGIS shapefiles.
