Maps & Tools

Below are links to maps and tools that have been developed to show or interpret information about Upper Columbia and listed spring Chinook, steelhead, and bull trout. GIS spatial data related to some (but not all) of these maps can be found through the Data Portal. Source of the map and data are indicated below. Contact for questions related to map content.

Snow2Flow Snowpack Decision Support Tool

UCSRB, in partnership with Ecotrust, has developed a free, online decision support tool that will help forest and stream restoration practitioners support salmon recovery across North Central Washington. The easy-to-use website informs salmon recovery by assessing the effects of forest restoration activity on snowpack retention and subsequent water supply and timing.

UCSRB has a whole-watershed, Ridgetop-to-River approach to salmon recovery. Water availability, especially during the late summer, is one factor that affects salmon populations in the Upper Columbia. One of several approaches to increasing the amount of water available for instream flow in the late summer is by increasing the capture and duration of storage of mountain snowpack. This tool builds on Pacific Northwest National Laboratory’s Distributed Hydrology Soil Vegetation model (DHSVM) to identify both how forest restoration activity affects downstream flows, and where to target upstream restoration activities to benefit specific in-stream locations.

There are three use cases:

  1. Identify good treatment areas by selecting the stream you wish to increase flow to
  2. Identify good treatment areas by region and other landscape considerations, or
  3. Explicitly draw your intended treatment area to see how streamflow will be impacted
