Thief Valley Reservoir, strategically positioned near North Powder in Eastern Oregon, functions as a substantial irrigation impoundment that concurrently provides an exceptionally productive coldwater fishery. Its location within a visually compelling valley contributes to its character as a premier destination for both recreational and serious anglers, predominantly managed by the Oregon Department of Fish and Wildlife (ODFW) for its robust populations of rainbow trout and highly valued kokanee salmon.

The reservoir’s primary piscatorial asset is its resilient rainbow trout fishery, rigorously stocked by the ODFW. Beyond this foundational program, Thief Valley distinguishes itself through a thriving kokanee salmon population, prized for their spirited battles and culinary excellence. For trout, a sophisticated array of techniques proves efficacious, including static bait presentations and dynamic spin-casting or trolling. Kokanee necessitate specialized trolling tactics with dodgers and hootchies at precise depths. Optimal angling periods for trout are spring and fall, while kokanee peak from late spring through summer. Access is comprehensive via public boat ramps and shoreline. Anglers are unequivocally mandated to consult the most current ODFW regulations, ensuring absolute adherence to species-specific limits and gear restrictions.
