It's a good fishery. How far you coming from, don't know where Johnstown is? I'm going to assume it's 2+ hours from here since I haven't heard of it. Not sure I'd drive hours at a time just to fish that lake, but if you are going to be in the area anyways it would be worth fishing. It's a fun little lake, but still big enough that I can't fish all my spots in 8 hours. Pike and tiger muskies in there too. The launch isn't a problem, not very steep and it's concrete. Guys launch smaller boats with Camry's and Volvos even. Never saw anybody have issues.
