Dad in the Yukon/Salmon Fishing

At Dawson Dad had a commercial fishing licence. The Yukon River was flowing at about 12 knots and was silty from glacier water, coming from the White River. He would net King Salmon. Down river (north) was Moose Hide and there was an Indian that had a fish wheel set up in the river. We went to see it. It turned with the current. It had troughs fastened to the wheel and as it turned fish would be scooped out of the water. Very interesting! It was a great invention.
