We had great fishing for samllies just below Sag Falls from shore! We stopped for a lunch and I happen to have a face mask, fins, and a snorkle along. I went swimming and found smallies stacked up in the shade of the big boulders under the water on the left side bank as you look at the falls area from below the falls. The next day the two kids and myself stayed down from the fish area, landed the boat, and fished the smallies from shore with night crawlers! It was a blast and the kids had the biggest fish of 4 lbs. 7 ounces of which we entered in the St.Paul Pioneer Press Contest. This was back in the 70’s.
Give it a try.
