Weather Impacts on Monitoring

Weather-related challenges have complicated late-season monitoring:

October 24: Bogus Creek, Jenny Creek, and Shovel Creek weirs removed ahead of forecasted precipitation

• Bogus reinstalled Oct 27
• Jenny reinstalled Oct 29
• Shovel reinstalled Oct 30

November 4: Scott River, Bogus Creek, Jenny Creek, and Shovel Creek weirs again removed for storm protection

• Sonar unit installed at Scott River site to continue monitoring
• Bogus reinstalled Nov 6
• Shovel reinstalled Nov 12
• Jenny Creek remains out as of Nov 14
• Scott River weir still out, operating sonar instead

Season Summary

The 2025 Chinook run delivered strong returns across all tributaries:

• Total documented Chinook: Over 9,500 fish across all five monitoring stations
• Peak migration period: Early to mid-October
• Late-season activity: Minimal new arrivals after late October
• Coho arrival: Began appearing in early November, approximately one month later than typical Chinook peak

Note: These counts represent net upstream passage at monitoring stations only. Significant spawning occurs downstream of counting facilities, particularly in Scott River and Bogus Creek. Sonar data from Scott River will be reviewed and included in the annual report. Final comprehensive escapement reports will be available after the season concludes and all data is finalized.
