I live in Pitt Meadows as well. Hook I know that exact dock your talking about, and I'm pretty angry theres a gate there. The only way to get to the dock is to swim during slack water, but I'm not going in that water. I've walked from the start of the **** all the way past the airport, and haven't found any real good fishing waters. There are either trees, logs in the water, or really thick brush to walk through. The only spot I have found that is kind of fishable is just past the dock on the edge of the water. There are a bunch of rocks to walk across. It's not the best place but i've seen a few fish rising out there, although that was back in July. Good luck.
