Salmon spawn in all the rivers and streams on the Pacific Northwest. At least they used to. They return to the same streams year after year. There are a multitude of theories about how they do this but we don’t really know. Even around Vancouver there are many streams where Salmon spawn and in some of them the runs are gone. Conservationists are doing their best to re-introduce Salmon into these streams. I’ve heard very pessimistic and optimistic reviews about this experiment. We shall see in years to come if they are successful.
This particular image is not of the Pacific Northwest as some of the flora is wrong. But I like it anyway.
