Yah mid week would be your best bet it can get busy in there. The lake never gets busy as its a big lake but the camp ground is not the biggest so it can fill up at times. Very few if any of the noise maker boats in there though generally speaking the people that head in there are in there to fish so it's generally a good crowd.
It is a beautiful place hammer well worth the visit a real gem. Absolutely stunning beaches long shallow beaches with not a soul on them it's really is a nice place.
Take a good assortment of deep diving Rapalas in with you and get your troll on. Both the big eyes and big northerns will take them,, have fun.
Take your camera we want pics..
Remember,, no bait on Seibert,, well technically lol,, you know just sayin !!
