Little Port Walter was the home of a herring saltery during the turn on the century and the ruins can still be seen. Little Port Walter had a small community at one time but has been replaced by a research station that studies the life cycles of several species of Salmon. There is a staff of 3–15 state and federal employees running the research station year-round. There is a dock, and the harbor itself is a safe anchorage. [1] [2]
