I've lived 15 minutes from that lake my entire life, and have never wasted a minute there... good crawfish I hear however
If fly fishing is your thing, try chironomids at pass lake, crawdad patterns where the rocks and trees are, and woolly buggers in the weeds, fly fishing only catch and release, no motors (gas or electric)
Campbel lake (the big one with the island in the middle) has some awesome sized fish, big triploid rainbows, fish them in the deep spot with a fly, or you can do marshmallows and worms off the boat launch at dusk, ask the old man at Lake Erie Grocery how to fish....
Best action is if you pack a boat into whistle lake in anacortes.... It's a mile plus hike, but it has some of the biggest lake fish on the west side, it's a big 400+ foot deep lake, with no motors allowed, an ultra light row boat or canoe is your best bet there
Lake Erie has bass, carp, and trout, and it can be good
Heart lake is a toxic cest pool, it's got it all, but the lake usually gets closed in the mid summer cuz of toxic algae or some gross thing like that
If you wanna try the salt for sea run trout and char, try Ala Spit, but mind the tide
Not much else is really worth while until the salmon show up, and then the beaches are hot hot hot
