We saw the same on my graph. We fished both days in somewhat the same vicinity, and kept walleyes, bows and cohos. What was interesting to me at least - Saturday, all the fish were stuffed full. The walleyes and 2 cohos with smelts 2-4" long and the bows with nothing but gobies. I guess I need to bone up on my goby knowledge. I thought they were kind of a shallow water mussel bed lover fish. Sunday, all 9 keepers were basically empty
