Add about 30 minutes or so to those times to guesstimate the times for Garry Point Park. Pay attention to the tide height as well.
When you're fishing those bays, either float fish or lure fish, that will keep your rigs away from the snags. At a moment, float fish would be better as water clarity is not great.
Later on the year, when clarity improves, you'll have a lot more fun spin fishing.
In September, October, when salmon fisheries are open, you'll be able to catch the odd coho, chum from those bays.
Not exactly an exotic location, but a pretty nice place to fish for a few hours without driving so far.
