The Rogue River in the U.S. state of Oregon begins at Boundary Springs on the border between Klamath and Douglas counties near the northern edge of Crater Lake National Park. The Rogue River flows generally west for from the Cascade Range through the Rogue River – Siskiyou National Forest and the Klamath Mountains to the Pacific Ocean at Gold Beach. Communities along its course include Union Creek, Prospect, Trail, Shady Cove, Gold Hill, and Rogue River, all in Jackson County; Grants Pass, and Galice in Josephine County, and Agness, Wedderburn and Gold Beach in Curry County. Significant tributaries include the South Fork Rogue River, Elk Creek, Bear Creek, the Applegate River, and the Illinois River. Arising at above sea level, the river loses more than in elevation by the time it reaches the Pacific. Of the river's total length, , or about 58 percent, is designated as National Wild and Scenic River – part on the upper Rogue and part on the lower Rogue. The Rogue is one of only three rivers that start in or east of the Cascade Mountain Range in Oregon and reach the Pacific Ocean. The others are the Umpqua River and Klamath River. These three Southern Oregon rivers drain the mountains south of the Willamette Valley. The Willamette River drains rivers to the north into the Columbia River, which starts in British Columbia rather than Oregon. Boundary Springs to Lost Creek Lake Flowing out of Klamath County and into Douglas County at the headwaters spring, the river runs north for about before leaving the national park and entering the national forest. Crossing under National Forest Development Road (NFD) 9281, also known as Old Diamond Lake Road, the river turns west parallel to the Upper Rogue River Trail, which is on the right. Parallel to the river and slightly north of the trail is Oregon Route 230, also known as the West Diamond Lake Highway. Shortly thereafter, the stream goes over a waterfall, receives Cascade Creek from the right and then Mazama Creek from the left at about river mile (RM) 211 or river kilometer (RK) 340. Two more waterfalls occur in the next before the stream turns to the south, passes under NFD 4901 just before receiving Minnehaha Creek from the left near Minnehaha Campground. The stream then meanders through Hamaker Meadows and receives Hamaker Creek from the left before passing Hamaker Campground, which is
