Well went out their on last Saturday, I only went out paradise valley rd and it's been plowed all the way to just past the BC hydro sign by the bridge that goes over that little creek. if you have a 4x4 you could go farther, but I was in my work truck and there smart to to give me that opinion cause I would abuse it. Fished the cheakamus for a few hours in a bunch of spots with no luck. Their in there somewhere just not many, even the DFO was out inspecting the area, don't be shocked if you see them rolling up on ya. All the rivers are a little too low still in squamish. I was over fishing chapman creek and the rainy river on the sunshine coast today and their rivers a extra low and gin clear with No fish in sight yet. I would try the squam it might be a little higher now, things can change a lot in a week.
Good luck and I would like to hear how you made out up their and what the river looks like, I wana go back that way soon in my cj.
