The Chenismus Forest Reserve was established in Oregon by the U.S. Forest Service on May 12, 1905 with 220,320 acres (891.6 km2). On March 1, 1907 it was combined with the first Wallowa National Forest to create Imnaha National Forest and the name was discontinued. Its lands presently exist as a portion of Wallowa–Whitman National Forest.
