The Madison chain of lakes has some good fishing. The bass fishing is very good. TBASS and I fished in a tournament Sunday and took 19 out of 60 with 4 fish for 10.5 lb. 22 lb. won it for a 6 fish limit with a 5.8 lb. big fish. This was the Cystic Fibrosis charity tournament launched out of Lake Farm Park on Lake Waubesa. There are weekly bass tournaments on Tuesday and Wednesday nights, that rotate between the chain lakes.
Lake Mendota is the biggest and has the best walleye and smallmouth fishing.
Lake Monona has good largemouth, with decent smallmouth fishing. Muskie fishing is good as well.
Lake Waubesa is primarly largemouth, with good muskie fishing.
Hope that helps you Dan and anyone else that was wondering.
