Most rivers are primary watersheds combining smaller streams called tributaries. Tributaries may include both spring and freestone water types. Many rivers do not provide the ample shade of smaller streams, so greater temperature fluctuations are common.
Rivers created by reservoir outflows often provide excellent fishing. If the water is released from the bottom of a dam, it often has the necessary ingredients for good trout habitat. This type of river, defined as a tailwater, provides consistent cold water temperatures. Many tailwater fisheries provide an abundance of smaller insect life, such as Chironomidae, and nourish big trophy trout. Catching a large trout on a small hook is difficult, yet extremely rewarding.
