i drove by there last year to check it out and found that you can not use downriggers. its a deep clear lake so I would rig with spoons and large jigs. the take is one or two per day.
you could always troll flys way back from the boat with some lead core in order to get down. from the regs i believe that you can only use 3 ozs of lead . I have been wanting to go back with the boat but with such restritions I dont know if its worth it. the local store on the lake was not much help for fishing in fact i got the idea they did not like fisherman.
