The entire Chain holds some good Largemouth, we were up there 7/14 - 7/21. The Largemouth were holding in healthly looking green weeds and the lily pads. The back Bay of Thousand Island prior to entering the channel that leads to Africa and Record Lakes was very productive for Largemouth. Topwater baits worked best.
The fish holding in the lily pads were in the large thick pads, sparse pads were not holding fish. The channel leading into Cisco lake has a great strech of thick pads. Creature baits flipped with 1/2 oz weights pegged, in the thick pads produced the best fish. Color of the plastics didn't make much of a difference.
Hope this helps. Good luck.
