Catching a large trout{lunker} is far from a crap shoot. Luck always plays a factor, but it is certainly not the most important thing you need to know. First off a lunker by most standards is a trout weighing more than 3 pounds. The phrase lunker was coined in the trout parks 40 plus years ago. Everyone has given you some good info like location, polorized glasses,and bigger baits. I have friends who consistantly catch lunkers on bigger flies, and lures. I am not so much on really big flies. A size 10 is about my max. I know that you prefer to fish bait and you can use the same principles in bait fishing as I do fly fishing. Unlike brownieman, I am a sight fisherman. I will walk the creek bank untill I find a fish that I would like to catch. The easiest way to catch a large fish is to know where he is located before you ever fish. I prefer to get close enough to the fish, to have a good visual on him while I am making my presentation. By close I am talking 20 feet or less. You need the sun to your back if possible and you may have to cross to the other side of the creek. At 20 feet from the fish, be 5 feet upstream of the fishes location. With bait or fly or spinning gear simply drift your offering close to the fish at "his level" in the water. Do not crowd him with your presentation. A good rule of thumb is to keep your offering at least 1 foot on your side of the fish. If he likes it, he will come to it. If not he will ignore it. Change offerings immediately if he ignores your presentation or acts like it bothers him. If you don't, you will most likely spook him off. If he ignores the first five offerings, those usually being your best, back out of the water and leave him alone for a couple of hours. But always come back. Just like Brownieman told you, always go back and try him again. I have had fish in the trout parks that I have spent as much as 3 months trying to fool. Some times you win, some times you don't. I caught my first lunker in 1975, and it is still as big a thrill right now as it was then. Every encounter with a big fish should be filed away in your memory banks for a future situation. I have always kept a log book for the big fish that I have caught. Over time you can look back in the log book and maybe see a pattern as far as flies, type of water and so on. Big fish are out there and they can be caught. It's all up to you on how much time and patience you are willing to part with. I have been fortunate in my lifetime to have caught several hundred lunkers. I have caught 3 pounders and I have caught giants, and each one is special regardless of size. Chances are in your favor to catch a lunker. Remember what Brownieman, gavin, brian, bman and the others have told you. It's the right advice you need for catching that lunker. You "better" let us know when you do! Good fishing!
