In Arkansas the question of where to fish is probably more easily answered with a list of where not to fish—because it would be an incredibly short list. The Ozark region in Northwest Arkansas, along the White River, is some of the best brown trout fishing in the world. You'll also find striped bass in the waters near Mountain Home. The lakes of Central Arkansas are always on the largemouth bass pro circuit tour. And the rivers and backwaters of the Delta are where you'll find catfish the size of a 10-year old boy.
