Antelope Reservoir is a large body of water impounded for irrigation in a semi-arid region of southeastern Oregon in the United States. Located near the small city of Jordan Valley in Malheur County, it is about 10 miles (16 km) west of Oregon's border with Idaho. Although the lake is formed by a dam across Jack Creek, most of the water enters the reservoir via the Antelope Feeder Canal. It diverts water to the reservoir from nearby Jordan Creek at a point near the Idaho border. Jack Creek, which carries minor outflows from the reservoir, empties into Jordan Creek further downstream.
