# Monroe Bend – Coho Salmon Briefing Monroe Bend rates **Excellent (80/100)** for coho right now, driven primarily by strong fish abundance—recent counts are 45% above baseline at 850 fish—and stable weather, though river flow is running high at 3120 cfs, well above the ideal 600–2200 cfs range. However, confidence is modest at 37% because water temperature data and recent angler reports are unavailable, both of which could materially shift conditions. Fish are present in good numbers, but the elevated flow may be pushing them through faster or deeper than usual—scout carefully and consider how high water affects your presentation.
