Featureless? Seriously?
It's pretty clear you haven't spent any real time fishing Erie, or you wouldn't say such a thing. There's a ton of structure and cover if you know what to look for. The lake is an amazing place to fish, especially if you like big bass.
Not sure if they still run it or not but there used to be an opening weekend smallmouth tournament that ran out of Buffalo ... it was a two-fish limit and if you didn't have 12 - 13 pounds, you wouldn't even crack the top 10. The problem ... if you want to call it that ... was culling four and five pound smallies one after another, all day long, while trying to get a bigger limit. I can't think of too many other lakes in Ontario where you have that kind of trouble.
Walleye fishing on Erie is legendary. It coughs up some of the biggest muskies caught in Ontario every year. Summer trolling for steelhead is mind-boggling, and the east end of Erie has some of the biggest lake trout this side of Nunavut. It has jumbo perch, big pike, some major slab crappies ... man alive, what more do you want?
And yeah, Sinker is absolutely right - you see huge numbers of high-end bass boats out there that bristle with rod holders. Some of the US boats like like porcupines. If you've never seen rod holders on a bass boat, then you need to try fishing somewhere other than the Kawarthas.
