Pacific salmon
What do the Columbia River and and Great Lakes have in common?
Fishing for salmon.
Just back from a National Geographic cruise on the Columbia and Snake Rivers. The Columbia River has been dammed for electric power and the Pacific salmon that used to crowd the Columbia River are not found above the locks and dams in any good numbers.
I took the video below the locks and dams. I also took a trip up the wild Snake River where white sturgeon are found and the steelhead run. The steelhead were not running yet. The water was too warm I was told. But they were expected in spite of invasive species of fish in these waters.
We went through Hell's Canyon and I could see how it got that name. My imagination went wild there seeing all sorts of figures in the convoluted rocks. We came to the confluence of the wild Salmon River (The River of No Return).
I am pleased that Pacific salmon are living in the upper Great Lakes. This was an idea that has worked. To learn more about how Pacific salmon happened to be planted in the Great Lakes read my book, The Dynamic Great Lakes. This critcally acclaimed book is widely available on the www and in many bookstores.
