Small rivers and streams often feature everything that makes for a great fishing trip: interesting fish, ever-changing environment, and beautiful scenery. Unlike small ponds, which usually start with an introduced population of fish, streams run wild and may carry wild populations of fish.

The majority of streams and rivers follow a pattern known as riffle-pool-run. A riffle is often visible — the water will churn as it flows over a harder bottom. Riffles are shallower than the surrounding water, and mark the beginning of a pool — the area where the current carves away the bottom after tumbling through the riffle. Pools are the deepest parts of the river. Runs occur where the river assumes a fairly stable depth until the next riffle. (Turn to the color section to see how these three elements come together.) Although the depths of a pool might range from a foot or two in a stream to a hundred feet in a large river, the basic pattern remains.
