Started out Sat. morning from Gem Beach Marina and was going to fish for walleye between Niagra and Green Is. and the lake turns us to fish on the leeway side of the Islands, Balist Is. shoals. Caught around 50 perch and the lake turned into 2 to 3 footers in the afternoon, so we decided to go to Gull shoals, and fished the rest of day for walleye. Nothing but sheephead. Should have stayed perching. Sunday we went back to Balist Is. shoals and we caught 100 perch from 7:45 to 10:00am and ran out of minnows. 5 fishing in our boat. Cardinal sin, always buy enought minnows for the Islands do not have a bait stores. Rookie mistake.
