Weekend boat traffic is always a flip of the coin... You never know how crowded or when there will be gaps... I think there is plenty of lake for everyone to participate at what they like. I typically go through the week and the last time I was there on a weekend, it was kinda enjoyable in the sense that the pontoon and ski boats do get a little close at times but you get to revisit all the 70's and 80's music they play... Last time, a pontoon was blaring Brandy, you're a fine girl, what a good wife you will be and it took me half way back to Valpo on the road to get that song out of my head... And of course, another Koontz lake favorite besides anything from the Beach Boys is the Wreck of the Edmund Fitzgerald...I will say, the turbulence from all the boats seems to improve the fishing. It kind of stirs up the lake and I think they seek refuge near the fisherman's boat as it is an oasis of more quiet and less waves...
