If after that long drive, and longer hike you find someone fishing the pool you came all this way to fish, feel free to be disappointed, but do not feel free to wade in. If you are determined to work that favorite stretch, sit on shore and wait till the other guy is done. Better yet go elsewhere.
If some ignorant clod comes into the pool you're working; Explain to him, politely the error of his ways. If that fails and he (or she) decides their fishing is more important than yours. Do not stoop to their level. Hard as it seems, I recommend you move on. First you're less likely to catch anything with a bozo (or bozette) like that in the pool. Second the stress of having to be around this kind of clod is not worth the trouble.
If you're working your way downstream and come across someone working upstream, yield to the angler working upstream. This is an old rule from the time of Hewitt and Gordon.
In the event you find yourself sharing a pool with one or more anglers, give yield to anyone fighting a fish.
Do not laugh at casting flubs, unless they are your own.
Never second guess another angler's selection of fly. Too many fish have been caught on a Royal Wulff for you to get cocky about your hatch matching skills.
Avoid using the stream as a path. Walk from pool to pool on the bank. Leave a pool as quietly as you entered it. This means the pool needs less rest for the next angler that comes to it, if you are lucky it may be you.
If you see someone working a fish, or waiting one out, give them a wide berth, preferably by going to the next pool.
Talking to another angler is acceptable, and quite proper.
Not talking to another angler is acceptable, and quite proper.
Do not litter, and do not tolerate litter around you. Pick it up.
If you smoke, take your matches and your butts out with you. Forest fires should happen on their own not with your help, so pay attention.
Respect fences, leave gates the way you found them, close the ones you opened and leave the open ones open.
Show the same respect to spin fishers as you do to fly fishers. Elitism has no place on our rivers. If you really think fly fishers are better, prove it by living up to a higher standard not by expecting less of others.
Offer advice only if asked, ask only if willing to listen.
No trespassing, means no trespassing. If you really want to fish there, ask permission. You will be surprised how many folks say yes. But NO means NO.
Cellular phones, beepers, radios and television have no place on the river.
Be especially mindful of your manners and language around youngsters. They learn best by example.
Swearing, farting and burping are at the discretion of the angler, and quite acceptable. (Note previous rule.)
Lying is still acceptable, even expected, if asked how you did, or where you were. Lying about the hatch is not as decorous, but tolerated. Lying about your residency is illegal when purchasing a license. Lying in the grass and taking a nap is one of life's great joys.
Never interrupt a lying fisherman.
Enjoy yourself, but not at the expense of someone elses enjoyment.
Catch and Release.
