Stand at the underground viewing window at the Ballard Locks this week and you're watching something the state of Washington itself couldn't quite predict. On September 15, the Washington Department of Fish and Wildlife closed coho salmon fishing across a wide stretch of Lake Washington, from north of the 520 bridge down through the Montlake Cut and into the Sammamish River near Kenmore. Three days later, on September 18, the agency reopened it, citing fish counts at the Locks that had improved significantly in a matter of days. Coho fishing is now open through October 31.
That whiplash is the real story this year, and it's a better reason to visit than the line every visitor guide repeats about coho peaking in September. The calendar says one thing. The fish, this particular season, are saying something more complicated.
What the counts were actually showing
The Locks have functioned as the region's salmon checkpoint since long before anyone thought to build a viewing room around it. Every Chinook, coho, and sockeye moving between Puget Sound and the Cedar and Sammamish watersheds passes through the fish ladder on the south side of the complex, and WDFW and the Muckleshoot Indian Tribe have counted them there since 1972, co-managing the run and using the daily numbers to set fishing rules in real time.
This year those numbers gave fair warning before the coho closure ever happened. Even the Chinook run, which typically peaks in August and usually gets the most attention, was already tracking softer than usual. Nearly 4,800 Chinook were counted at the Locks between July 29 and August 16, and while the migration was accelerating through mid-August, the cumulative count remained below the totals from the two previous completed runs, 18,522 in 2024 and 19,872 in 2023. So when WDFW's in-season data flagged the coho return as smaller than forecast in mid-September, it fit a pattern that had already been building for weeks, not a sudden surprise.
What changed by September 18 was that the numbers turned around fast enough for the state to reverse course inside the same week. That kind of swing is exactly why the daily counts matter more than the seasonal guide. A visitor guide can tell you coho peak in late September on average. It can't tell you what the ladder looked like yesterday, or whether this is one of the years the average doesn't hold.
The orcas that showed up for the wrong salmon
The Locks got a stranger kind of attention back in August, when a pod of transient killer whales turned up in Salmon Bay itself, close enough to the spillway that visitors could hear their echolocation clicks. Local field biologist Kersti Muul, who runs Salish Wildlife Watch, a WhatsApp-based sighting network, had been tracking the group as they moved past Whidbey Island and Edmonds before they turned up at the Locks. Researchers identified several individuals, including one known to regular whale watchers as T-137A, or "Jack."
The timing looked poetic. It wasn't quite. These were Bigg's killer whales, the transient population that hunts seals and sea lions rather than fish, so the Chinook moving through the ladder that week weren't the draw. The seals gathering below the spillway to prey on those same Chinook likely were. Shari Tarantino of the Orca Conservancy, who has tracked orcas in the region for fifteen years, told KIRO 7:
"I've been here 15 years, I don't recall orcas going into the locks."
The Army Corps of Engineers, which operates the site, called it a coincidence worth noting anyway, writing that the appearance was "an exceptional reminder of the ecological connections that extend from the Ballard Locks all the way to the Salish Sea." It's not the first time someone tried to manage that predator problem by force. Two decades ago the city floated a fake orca near the spillway to scare off seals. It didn't work. The statue, known as Fake Willy, was donated back to the Locks in 2019 and now sits near the visitor center, a small monument to an idea that never landed.
How to actually check before you go
The lesson from both the coho reversal and the orca visit is the same: this stretch of water doesn't run on a fixed schedule, and the people who get the best visits are the ones checking current conditions instead of trusting the brochure copy. A few ways to do that before you head over:
- Look at WDFW's Lake Washington salmon count page directly. Chinook counts are typically posted from late July through September, and coho counts run from early September into October. The data is preliminary and updates through the season.
- Check the fish ladder viewing windows in the early morning or on a weekday afternoon. Weekend crowds build fast once word gets out that a run is strong.
- Watch local wildlife sighting channels, including Salish Wildlife Watch, if you're hoping to catch anything unusual in the water. Orca visits to the Locks remain rare enough that they're still news when they happen.
Making the trip worth it either way
Even in a slow week for fish, the Locks reward a visit on their own terms. The complex covers 18 acres and includes a botanical garden alongside the working locks, where boats ranging from kayaks to commercial trawlers get raised or lowered up to 26 feet in a process that takes ten to fifteen minutes. The fish ladder viewing room is open daily from 7 a.m. to 8:45 p.m., and the grounds stay open until 9 p.m. The visitor center runs 10 a.m. to 6 p.m. daily through September, then narrows to Thursday through Monday, 10 a.m. to 4 p.m., once October arrives.
Dogs are welcome on the grounds on a leash, though not inside the visitor center or the underground viewing room itself. A small concession stand operates during peak summer months, but takeout from Ballard proper, carried over to the lawn by the botanical garden, is the better call most weekends. The pedestrian walkway across the top of the lock gates doubles as a genuine shortcut between Ballard and Magnolia, and it's the same stretch of water where the orcas surfaced in August, which makes the crossing a little more interesting than the average commute. If you want to round out the afternoon, the Nordic Museum sits a few blocks off in Ballard's old town, and Golden Gardens, the beach that also had its own orca sighting that week, is a short walk beyond the Locks' north side.
None of this requires the fish to cooperate. But this particular September, with a coho run that closed and reopened inside four days, checking the count before you go isn't just good practice. It's the only way to know what you're actually walking into.
