Thank you for cross posting! To keep that thread more on-topic (whatever that topic is...)
I run fairly regularly on the millvale-northside trail now, and past few times there have been people swinging from a rope swing into the river from one of the bridges closer to millvale - not that high. It looks like a gas, but I also recall spots in the river being shallow enough that wading didn't even look like fun.
Is there somewhere online to see some kind of nautical maps of the rivers, with depth... I'm thinking of the maps all the kayakers have of the tides and islands in BC, but since we have no tides I'm not sure what they'd show, or what they're called, or where to look for them.
Any help?
