Marmot Dam Reach

**Verdict:** Marmot Dam Reach rates as Excellent for Coho right now, but proceed with moderate caution given incomplete information. Fish populations are strong—recent counts hit 400, a 40% jump above baseline—and weather conditions are favorable with stable pressure and manageable wind, which together account for most of the high score. However, the 37% confidence reflects significant blind spots: water temperature data is missing (critical for Coho activity), recent angler reports aren't available, and flow at 584 cfs is slightly below the optimal range, which slightly dampens the outlook. Before heading out, confirm current temperature and recent success reports if possible.
