There used to be salmon as big as golden retrievers in the Columbia River, but dams killed them off

When I was a kid in the middle 50’s early 60’s living in Clarkston Washington, I remember walking across the Interstate bridge spanning the Snake river (a tributary of the Columbia river) and seeing what appeared to me to be blood running down the riveras far up and down as I could see. I was frightened and upset and ran back to the Clarkston side yelling that there was a large amount 0of blood in the river 75 feet wide. An oldman started smiling and took my hand to calm me down and said that is just the color of the sides of the returning salmon, and he walked me back out to the center of the bridge and showed me. This went on for several days.
