Since you know the location, the story went like this:

Parker fights the fish in the "bucket" for a while. Parker swears at Sparkey and wonders why he's getting his ass kicked by a steelhead. Must be a spey thing. Fish finally decides to come in closer to shore and Parker and fish start working in towards a landing. Parker get's to see the fish and pee's his pants. Parker get's another good look at the fish and craps his pants. Fish says "piss off" and decides to go down river. Fast. Parker does his best "Jesus/Moses" imitation and starts to walk on water running after the fish. Fish hits the top end of the white water and Parker thinks it's all over. Fish decides to move right, and STOP in the eddy at the little "spit" that is accessible. No one, including Moses/Jesus is going any further than that spit, as it's all deep fast white water from there to around the corner. Fish is tailed and the rest is history.

Only The Chosen One could get away with something like that.
