Nestled in the far eastern reaches of Oregon near the Idaho border, Lake Owyhee (also called Owyhee Reservoir) stands as Oregon's longest reservoir, stretching an impressive 52 miles through scenic desert canyons. Created in 1932 with the completion of the Owyhee Dam, this 13,900-acre artificial lake reaches a maximum depth of 117 feet with an average depth of 81 feet. Beyond its recreational value, Owyhee Reservoir serves as a critical irrigation source for 1,800 farms covering 118,000 acres across Eastern Oregon and Southwestern Idaho. The reservoir's remote location has kept it relatively uncrowded, offering anglers a chance to find their very own cove teeming with fish in a dramatic high desert canyon setting.
