You will see lots of boats South of the Keystone Terminal. Most of the boats will be along a line West of the Lake Handcock inlet, check your chart.
Charts and the GPS are in the boat, stored about a mile away or I'd get you some numbers. Look for about 150-200 feet of water. Should be a good number of boats.
Also from salmonuniversity.com Terry Rudnick posts these:
The "Humps," a series of fairly sharp drop-offs just northwest of Port Angeles.
Coyote Bank, an underwater plateau that spans the US/Canada border northeast of Port Angeles.
Hein Bank, the large underwater plateau about eight miles north-northeast of the Dungeness Light.
Eastern Bank, another large plateau about four miles southeast of Hein Bank.
Dungeness Bank, a good-sized plateau off the tip of Dungeness Spit, near Sequim.
Dallas Bank/Protection Island, near the entrance to Discovery Bay.
Smith Island and Partridge Bank, at the north and south ends of a vast series of flats and drop-offs with miles of potential halibut-holding water.
