Imagine this: you come to the river, and there’s a huge sea lion sitting there, looking at you with intelligent eyes and letting out a loud roar. You laugh, pull out your phone to take a photo, and think, “What a handsome guy!” That’s exactly how thousands of Seattle residents must have felt in the mid-1980s, when an unusual guest by the famous Ballard Locks appeared—named Herschel. But behind this sweet story there was a real drama: a tale of how one city tried to both love nature and protect it, and how those two things suddenly turned out to be incompatible.
The Locks That Became the Heart of the Neighborhood
The Ballard Locks are an engineering marvel on the edge of Seattle. They were built in 1917 and connect freshwater lakes—Lake Washington and Lake Union—to the salt waters of Puget Sound. Picture giant gates right in the water: a ship enters a special chamber, the water rises or falls, and the vessel ends up at a different level—like an elevator, only for boats. It was a genuine technical achievement of its time, and locals were proud of it.
But even when the locks were only just built, fishermen and scientists noticed something troubling: salmon stopped returning home. Salmon are remarkable fish. They are born in freshwater, swim out to the ocean, and then return to the very place they hatched to lay their eggs. This journey spans thousands of kilometers, and the fish makes it with flawless precision. But the locks became a barrier for them.
