Something I never considered: I recently read that for every foot of height gained or lost to the water, casting distance (in theory) is changed by 9'. Someone 6' 5" will have an additional 9' of casting distance over someone 5' 5". Same goes for rod length and wading. While reading this information, I kept wanting to say "visibility", but distance is the term used! Wading is where it struck me! If the gradient on the river bottom is 1' in 5' (rise over run), and you wade in 10', you are actually 8' further away from the area you were trying to reach. Any gradient more than 1 in 9 and there's no point in wading. I am interested to know what others think as it's a new principal to me. There are reasons of course where wading creates room for a backcast, but it's something to think about. Plus getting wet is a requirement for having fun.
