# Monroe Bend on the Snohomish River – Coho Salmon **Verdict:** Excellent conditions today with a score of 91/100, though moderate confidence warrants cautious optimism. **Why:** River flow at 1440 cfs is squarely in the ideal band (600–2200 cfs), accounting for 68 points of your score, while today's weather—full cloud cover, light 11 km/h wind, and stable pressure—adds another 23 points and should keep fish active and feeding. **Caveat:** Fish count data, water temperature, and recent angler reports are all unavailable, which keeps confidence at only 37%; before you commit significant time, consider calling local fly shops or checking recent social media posts for current catch reports and exact water temp.
