Regional decision desk
Three moving systems make this region unusually well suited to live tools: vessels and fish at Seattle's locks, salmon moving up the Columbia, and a major dam destination whose lake, flows and visitor schedule change the trip.
What to check first
The regional page does not blend unrelated signals into one score. Ships, salmon passage and dam visitation each keep their own evidence.
See the latest adult counts at Bonneville, The Dalles, John Day and McNary, plus the seven-day direction for Chinook, Coho and steelhead.
Check Columbia salmon counts →Use vessel traffic, salmon counts, tides, weather and visitor context to decide when the locks are likely to be most interesting.
Check Ballard Locks →Lake Roosevelt level, dam outflow, tours, laser-show timing and weather matter more than a generic attraction-hours page.
Check Grand Coulee →Regional tools
Each tool is narrow on purpose. It should answer one travel or viewing decision well instead of becoming a giant Pacific Northwest dashboard.
Columbia River · Oregon & Washington
Follow reported adult salmon passage from Bonneville through McNary and see whether recent counts are rising, falling or holding.
Best for: visitors, anglers and fish watchers who want current run evidence rather than only a seasonal calendar.
Fish Passage Center + USACE fish-count methods and run timing
Open Columbia Salmon Run LiveSeattle · Washington
Combine vessel traffic, salmon passage, tides, weather, chamber context and the live visitor experience at one of Seattle's most unusual working-waterfront destinations.
Best for: visitors choosing when to see boats, locks and fish activity rather than simply checking opening hours.
AIS + WDFW salmon + NOAA tides + NWS weather + USACE operations
Open Ballard Locks LiveGrand Coulee Dam · Washington
Plan the visit around Lake Roosevelt level, Columbia River outflow, available operational context, visitor tours, laser-show timing and weather.
Best for: road-trip visitors trying to turn a major engineering landmark into a timed experience.
USACE water + Bureau of Reclamation visitor information + NWS
Open Grand Coulee LiveRegional rhythm
The three tools peak at different times and for different reasons, which is useful for regional search depth instead of concentrating all traffic into a single event week.
