I haven't been lately, but I have a suggestion. Give them a call. Their number's on their web site: http://www.guistcreek.com/ Whenever I've called, they've told me straight up whether the fishing's been good or "slow," and they'll tell you if you'll have trouble launching.
Oh, and it's getting towards the time of year where shiners trolled deep and slow in the deepest part of the lake can produce 10-12 lb. hybrids. Not that it can only happen in cold weather, but that seems to be the best time. Good luck!
