My charts are on my boat, but I believe it is on either chart 3603 or 3602. I know for sure it shows up on my GPS CMAP for the area as well. I have not fished there in two years, but last time I was there is was absolutely on fire for springs between 15 and 25 pounds, the were hitting like Coho's we could not get our downriggers down all the way before they would hit.
