The Okanogan–Wenatchee National Forest is a U.S. National Forest located in Okanogan County in north-central Washington, United States.
The 1,499,013-acre (2,342.208 sq mi; 6,066.29 km2) forest is bordered on the north by British Columbia, on the east by Colville National Forest, on the south by the divide between the Methow and the Stehekin–Lake Chelan valleys, and on the west by North Cascades National Park. The closest significant communities are Omak and Okanogan.
Managed by the United States Forest Service, its headquarters are in Wenatchee. It is the second-largest national forest (after the Nez Perce National Forest in Idaho) that is contained entirely within one county and largest of which in Washington.
Most of the Pasayten Wilderness (excluding its westernmost part, which lies in the Mount Baker-Snoqualmie National Forest), and the northeast portion (about 63%) of Lake Chelan-Sawtooth Wilderness are part of the forest, with the balance lying in the Mount Baker-Snoqualmie National Forest.
The western part of the forest is wetter than the dry and less temperate east. The vegetation varies similarly, from the western boreal forest, to the eastern high-elevation steppe. A 1993 Forest Service study estimated that the extent of old growth in the forest was 316,000 acres (128,000 ha), a majority of which was lodgepole pine forests. Wildfires are not uncommon in the Okanogan National Forest. Notable fires include the 2006 Tripod Complex, the 2014 Carlton Complex and the 2015 Okanogan Complex fires.
The Okanogan National Forest was established on July 1, 1911, from a portion of the Chelan National Forest. On July 1, 1921, the entire forest was transferred back to the Chelan National Forest, but on March 23, 1955, the transfer was reverted.
The Wenatchee National Forest has an area of 1,735,394 acres (2,711.55 sq mi, or 7,022.89 km2); it extends about 137 miles along the eastern slopes of the Cascade Range of Washington, USA from Okanogan National Forest to Gifford Pinchot National Forest. The forest is located in Chelan, Kittitas and Yakima counties.
