Angler briefing
generated · claude-haiku-4-5**Verdict:** Marmot Dam Reach rates as Poor for Coho today (41/100), so plan accordingly or scout alternatives. **Why:** Low river flow at 229cfs—well below the ideal 600–2200cfs range—is the primary concern, accounting for 17 points of the score. Clear skies and falling pressure (23 pts) are also working against you, as Coho typically favor overcast, stable conditions. However, confidence in this assessment is only 37% because fish counts, water temperature, and recent angler reports are all unavailable, meaning conditions could be better or worse than this score suggests.
