lakefront lillypads

So I assume I am like a majority of people here who would do just about anything to actually own a piece of lakefront. I always look, even though I am probably no where near able to purchase. Anyone else do this? I just figure if I find just right spot at the price too good to pass, then maybe I can rearrange a lot of things and maybe, just maybe, make it happen. Anyway, my realtor just sent me a link to house on a local lake. The house looks liveable, it has rickety dock, and its surrounded by lillypads...neighbors too. So I know I can't be picky if I'm gonna live on the lake, but are lillypads a deal breaker? Do lillypads indicate a nasty water or anything like that? And can they be removed with treatment of some sort? For boating I don't really care much, but if we're gonna live on the lake one of the benefits is that we can swim off our own dock and lillypads just give my kids the heebies...
