The RAD provides data-driven information on restoration to support Trinity River ecology and fisheries below Trinity and Lewiston Dams, all the way to the confluence with the Klamath River. These data are primarily tabular, but will link out to other forms of data including maps. We intend to include all restoration activities within the Trinity River watershed that benefit mainstem fisheries. However, TRRP is only responsible for data on our own activities. Corrections may be submitted to the TRRP Data Steward. All data is provided as-is with no guarantees or warranties.
