For anglers seeking a distinctive challenge, the Lost River near Bonanza, Oregon, offers a unique opportunity within the Klamath Basin. This river is known for its fluctuating flows, which are significantly influenced by irrigation needs, sometimes causing sections to become shallow or even disappear. Despite these dynamic conditions, the Lost River supports populations of rainbow trout and occasionally native redband trout, making it a rewarding pursuit for those who understand its character.

Fishing success here hinges on monitoring current flow rates and water quality. Optimal conditions often present themselves when flows are moderate and water temperatures are favorable, typically outside the peak summer irrigation season. For trout, light spinning gear with small artificial lures, or fly fishing with nymph and streamer patterns, are effective methods. Anglers should be prepared to adapt their approach based on the river’s ever-changing environment.

Access to the Lost River can vary, with some public points available, though much of the surrounding land is private.
