A closer look at the destination

John Day Dam is 216 miles upstream from the mouth of the Columbia River and located at Exit 109 off Interstate 84 in Oregon. The project consists of a navigation lock, spillway, smolt monitoring facility, powerhouse and fish-passage facilities on both shores. Many recreation opportunities are available along the shores of Lake Umatilla and on the John Day River, such as boating, fishing, swimming and sail boarding.
