NOTE: It should be noted that the following information is directed toward brookie fishing in mountains along the east coast of the US. We are discussing getting started catching these little gems in streams that you can usually jump across while enjoying the solitude of the forest. Please do not try these techniques on your next trip to Labrador! A Canadian brook trout will snap your 3 weight like a twig.
Fly fishing for brook trout doesn't need to be expensive or complicated. The most difficult part is locating likely spots. This is in part due to environmental factors such as development and pollution. Brook trout are extremely sensitive to acidity and warming (caused by loss of cover and/or global warming) so you will often need to seek out remote locations to increase your odds. A trip to the local fly shop and a good attitude should get you some promising leads. I also rely heavily on topo maps to locate promising stretches of water.
In this section we will lay out the basic equipment and techniques that should get your lines tight in short order and under budget. When I was a kid I caught thousands of brookies on a $.75/week allowance so money needn't be a factor. A little patience and a lot of walking should make all the difference in the world.
