I arrived at low tide and I couldn't believe my eyes. There where oysters as far as could see in nearly all directions. I had been here 12 or so years ago and it wasn't anything like this at that time. There are at least five different species of oysters in Puget Sound and Hood Canal, with the Pacific oyster being the most common. Most of these (including the Pacific oyster) are introduced. Many of the wild original oysters have died off or where considered not market worthy.
Along the west side of Hood Canal where Eagle creek enters. Where these creeks enter Hood Canal is where the oyster beds are. The creeks are glacier melt and supply a lot of oxygen - creating a perfect habitat for oysters.
