It drains approximately of Jackson County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin. Flowing predominantly west, they meet near the city of Butte Falls. The main stem flows generally northwest until it empties into the Rogue River near McLeod, about one mile southwest of William L. Jess Dam and Lost Creek Lake. Big Butte Creek's watershed was originally settled over 8,000 years ago by the Klamath, Upper Umpqua, and Takelma tribes of Native Americans. In the Rogue River Wars of the 1850s, most of the Native Americans were either killed or forced onto Indian reservations. The first non-indigenous settlers arrived in the 1860s, naming the creek after Snowy Butte, an early name for Mount McLoughlin. In the late 19th century, the watershed was primarily used for agriculture and logging. The small city of Butte Falls was incorporated in 1911, and remains the only incorporated town within the watershed's boundaries. Big Butte Springs, located in the watershed, provides clean drinking water to more than 115,000 residents of the Rogue Valley. It emits over of water per day. Water from Big Butte Creek is also diverted for irrigation at several other locations. The water quality of the Big Butte Creek watershed is generally high, and it supports several species of trout and salmon. The watershed is also home to more than 152 species of birds, 63 species of mammals, 19 species of reptiles, and numerous plants. The Poverty Flats region was designated an Area of Critical Environmental Concern by the Bureau of Land Management in 1995 to protect several rare species of plants. == Course == Big Butte Creek begins in the Cascade Range near Butte Falls. It flows generally northwest over approximately to its confluence with the Rogue River. The two main forks of Big Butte Creek, the North Fork and the South Fork, merge at above sea level, while the creek's mouth is located at an elevation of . The North Fork's headwaters are located on the slopes of the Rustler Peak. It flows southwest, receiving many small tributaries such as Jackass, Eighty Acre, and Friese creeks. Turning west, it flows just north of Butte Falls before merging with the South Fork. The South Fork begins at the confluence of two of its tributaries, Twincheria and Rancheria creeks. It flows southwest, receiving Fourbit Creek on the left. Fourbit Creek begins near Mount McLoughlin, where massive faults may allow water to seep into it from nearby Fourmile Lake in the Klamath River watershed. The South Fork turns west and receives Willow Creek on the left. Big Butte Springs are located on Willow Creek, and the Medford Aqueduct, which carries drinking water to cities in the Rogue Valley, parallels the South Fork from there all the way to Butte Falls. The South Fork flows over the Butte Falls—the nearby city's namesake—and merges with the North Fork about downstream. Big Butte Creek travels northwest, gathering McNeil Creek on the left and Clark Creek on the right, along with many other minor tributaries. This region contains many Class II and III rapids, as rated on the International Scale of River Difficulty. The stream is crossed by Cobleigh Road at river mile (RM) 9.5 or river kilometer (RK) 15, and Netherlands Road at RM 3 (RK 4.8). About before its mouth, Big Butte Creek cascades over Crowfoot Falls and is crossed by Crowfoot Road. It then flows into the Rogue River from its mouth at the Pacific Ocean. Big Butte Creek's mouth is about one mile southwest of William L. Jess Dam, and Oregon Route 62 passes just north of it. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Big Butte Creek」の詳細全文を読む スポンサード リンク
