Wild â 4.3 miles; Total â 4.3 miles. Zigzag River. The Zigzag River arises from the base of Zigzag Glacier at approximately the 5,000-foot elevation on Mt. Hood in Oregon's Cascade Mountain Range. The 4.3-mile segment of the river from its headwaters to the Mt. Hood Wilderness boundary is administered as a wild river. The river flows steeply over mud and pyroclastic flows through a sparsely vegetated area in a narrow canyon. The canyon rim itself and beyond is well-forested.
The Upper Rogue River Trail, a National Recreation Trail, closely follows the river for about 40 miles (64 km) from its headwaters at the edge of Crater Lake National Park to the boundary of the Rogue River National Forest at the mountain community of Prospect.he William L. Jess Dam, a huge flood-control and hydroelectric structure, blocks the Rogue River 157 miles (253 km) from its mouth. Built by the USACE between 1972 and 1976, it impounds Lost Creek Lake. The dam, which is 345 feet (105 m) high and 3,600 feet (1,100 m) long, prevents salmon migration above this point.
