Idahoiceman,
I don't remember for sure, but it seemed we were in 10 to 15 ft of water on Cascade.
I have not ice fished CJ or Lake Lowell. There was a man on the south shore catching some nice sized cats this summer. He was using trout minnows (dead of course). I was not sure CJ ice would be very stable. Internet reports were good from Magic last winter, however, friends of mine had much less glowing ones.
