Dropping crappie condos and other material sounds awesome and I am thinking about putting some out. What or how do you know that it is out of the way of the summer ski traffic? I don't want to tear anybody's boat up, or anyone. If I built a 20 foot condo and sunk it in 40 ft of water according to normal pool, would that be alright? I guess shallower stuff could be put out in stumped chocked coves were no one could possibly ski. Any suggestions or ideas on this would be much appreciated.
