Rio Blanco (Colorado) : ウィキペディア英語版 | Rio Blanco (Colorado)
Rio Blanco is a tributary of the San Juan River in southern Colorado in the United States. The stream originates in the San Juan Mountains and flows for 30 miles through the San Juan National Forest and private lands to its confluence with the San Juan River in Archuleta County, Colorado. Colorado classifies the Rio Blanco as an Aquatic Life Coldwater Class 1/Recreation Class 1 waterway supporting water supply and agricultural uses.〔(【引用サイトリンク】url=http://water.epa.gov/polwaste/nps/success319/co_rioblanco.cfm )〕 The river also features native cutthroat trout and introduced rainbow trout fishing. ==Restoration project== The San Juan-Chama Diversion Project, which was started in 1971, eventually led to reduced water flow and a loss of aquatic habitat in the Rio Blanco. In 1998, Colorado included a 12-mile reach of the lower Rio Blanco on its list of impaired waters for failure to support its aquatic life due to sediment. A project to restore the stream channel to match the altered flow regime, resulted in the river's physical and biological function and water quality being improved. In 2008, Colorado removed the Rio Blanco, including the 12-miles of the lower reach, from the state’s list of impaired waters.〔
