I have been diving Lake Crescent the last 2 months. Beautiful location and the vis is incredible. PM me, and I will set you up with one of my dive buddy Michael H and he has been getting the permits and dealing with the rangers. There is a dodge car about 200' deep and the warren car at 171'. The warren car is a memorial for the warren family that died in 1929, and the car was found in 2003, and unfortunately there have been divers that have been taking stuff off the car
. Probably the reason for the permits.
