Angler briefing
generated · claude-haiku-4-5**Verdict:** Marmot Dam Reach rates Poor (36/100) for Coho today, and you should expect limited success. The low score is driven primarily by flow conditions—at 198 cfs, the river is running well below the ideal 600–2200 cfs range, which significantly reduces fish activity and positioning (13 points deducted). Weather conditions provided some positive offset with heavy cloud cover and light wind stabilizing pressure (23 points), but couldn't overcome the flow deficit. Confidence in this assessment is limited to 37% due to unavailable fish counts, water temperature, and recent angler reports, so conditions could be better or worse than indicated.
