context_page_description: Rio Blanco is a stream that is tributary of the San Juan River in southern Colorado, 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. The river also features native cutthroat trout and introduced rainbow trout fishing.
context_section_description: Parts of the river range from 10 to 20 feet (3.0 to 6.1 m) wide, and fishing is permitted along the side creeks including Rito Blanco. Most of the trout are in the 7-to-12-inch (180 to 300 mm) range.
  There are 3 miles (4.8 km) of the river that were transformed by hydrologist Dave Rosgen, from being wide and shallow to a deep flow that now supports a variety of trout. Rosgen's plan included placing boulders and old trees on the river banks to direct the waters toward a channel that would be more defined. He also constructed a tube to divert away the gravel and sand, which allows water to flow through, but the sediment is routed to a holding area which is regularly emptied and used elsewhere. Cost of the renovation was about $1 million. The three-mile stretch may be fished by guests of El Rancho Pinoso, a privately owned ranch near the river.
