River Current/Velocity

I fished the Columbia at Vancouver yesterday (got skunked).  I wasn't too worried about pedaling back upstream because I cheat - I have a sail  .  But there wasn't enough wind, so I got a lot more exercise than I had intended.  Thought I'd post this link for others who are not aware of it:
