The group I was with went to Chatterton in 1971.  It was back when you could take car top boats and outboard motors.  It was a flunk, but one day the walleyes went crazy on Chatterton.  I didn't keep a running tally of how many walleyes we caught, but one day we had three triples.  A triple means all three of us had walleyes on at the same time.  We had lots of doubles, but I didn't keep track of doubles.  The next day fishing went back to normal.
The take away is some days/times the fish will go crazy, but you have to be there when they go crazy.
