A couple of lakes here in Bella Vista have it. Loch Lomond, the biggest lake, I think around 700 acres, got it pretty bad a few years ago. Grew right up to the top of the water, but the lakes group runs mowers on it, kills it around docks, and introduced a bunch of grass carp. They over did it last year and just about wiped it out. However, the bass population exploded on Lomond. I was having great days fishing 1/4 oz kastmasters over the weeds, perfect size to imitate the small shad whose population also exploded. Very healthy fish in the 1-4 lb. range, a blast on spinning gear. And the best bite was in late August through September when all the other lakes around here are slow.
Well last year wasn't so good once the milfoil was gone. Plus word got out and the pressure was unreal. Sure was a hoot while it lasted.
