Nautical chart question.

[Sea lyin’]

Whats the number of the nautical chart that’s south of Barkley sound? The one that butts up to 3671 and covers port renfrew and straight of Juan de fuca. Is it #3606? Thanks

3602 covers the approaches from about Wya Point to Juan de Fuca and out to sea Rat's Nose, tuna grounds etc- scale is 1-150,000
3606 is 1- 110,000 and is all of Juan de Fuca, but does come close to Barkley on the western side.

There is also a small chart with detailed view of Nitinat and Port San Juan -3647
