Yes, you can head up clear creek and do that, however I'm suggesting you try a significantly smaller creek for now (like maybe 6' or less across). Also, keep in mind with the high runoff going on right now, you are not likely to have much, if any luck. You want to be fishing it when you can see through the water.

As for knot tying, look online for some help, I'm sure a simple google search will give you TONS of how to's. Much easier to show you than to try and tell you, know what I mean?
