Practice catch and release for all trout, lets leave some fish for the next guy to enjoy as well as you coming back to fool them again. Monofilament line is non-biodegradable and can remain in the environment for over 600 years. The Berkley Company has a recycling program available for anglers, so please pick it up and take it home with you. Respect property rights. Some areas are now closed because other fishermen have not asked for permission, or have left trash on the bank. Give plenty of room to your fellow fishers. The first person on a section of water should be allowed to fish it. Walk on by (away from the water if possible) and have patience, they may be “resting the water.” There is always more spots on the creek to explore. Keep the noise down; trout are very wary. If you spook a trout near another fisherman it may shoot past other fish in that section of water, spooking them. The person working their way upstream has the right of way. Try to keep some distance between you and others nobody likes to be crowded on the water.
Etiquette that is at the root of fly fishing basics is respecting the environment and being courteous to others. As a result you will find most other fly fishers to be a great source of information and friendship. This adds up to a more enjoyable day on the water.
