I'm looking for some info on Castle Rock Lake & Pentwell in central WI. I know Castle is about 1500 acres bigger than the Chip and Pentwell is about 23,000 acres. Both are supposed to have Muskie's. Tried to get a download on a map from the WI DNR, my stupid computer won't do it. Do these lakes have islands, rock & weed bars. Anybody know of a mom and pop resort on Castle. This place would cut 2 to 21/2 hrs off our drive. Are these lakes connected and part of the WI. river, any help would be appreciated.
