1 Monitor Natural Escapement and Productivity of John Day Basin Spring Chinook Project # Oregon Department of Fish & Wildlife James Ruzycki Richard Carmichael Wayne Wilson Terra Lang Schultz Derek Wiley

2 Salmonid Productivity, Escapement, Trend, and Habitat Monitoring in the John Day River Basin Project # Oregon Department of Fish & Wildlife James Ruzycki Richard Carmichael Wayne Wilson Terra Lang Schultz Derek Wiley

3 Columbia Plateau

4 Objectives Provide accurate and precise status and trend data for Chinook and steelhead of the John Day River basin. –Escapement estimates –Population characteristics »Age composition »Distribution –Smolt-to-adult returns (SAR) –Smolt production –Habitat monitoring
