# Puyallup Flats – Chinook Salmon **Verdict: Excellent conditions today.** The score is driven almost entirely by ideal river flow at 774 cfs (well within the optimal 600–2200 cfs band), which accounts for 68 of your 91 points, while stable pressure and overcast skies with light wind add another 24 points—both favorable for salmon feeding. However, the 37% confidence rating reflects significant gaps: fish count data, water temperature, and recent angler reports are all unavailable, so while conditions look good on paper, you're fishing somewhat blind on actual fish presence and recent success.
