Where is the Marking Crew Now?

Tagging Fish for Release

The CRFWCO Marking Crew just returned from tagging Spring Chinook and Summer Steelhead at Dworshak NFH and Spring Chinook at Warm Springs NFH. These tagged fish will be released this spring and their detections at Columbia River dams will allow us to estimate survival and travel time during their juvenile migration to the Pacific Ocean.
