|The San Juan River begins at the confluence of its East and West Forks in Archuleta County, Colorado and then flows about 383 miles through Colorado, New Mexico and Utah to its confluence with the Colorado River. And while it does come within one half mile the river does not actually flow through Arizona. Both forks source above 10,000 feet in elevation in the eastern San Juan Mountains in the San Juan National Forest, but the first practical navigable elevation is at about 7,965 feel msl on Sand Creek for the East Fork, or at about 7,936 feet msl for the West Fork. The confluence sits at about 7,578 feel msl. The river flows southwest through the foothills of the Rocky Mountains through the town of Pagosa Springs to its confluence with the Navajo River, where it turns west and heads into Navajo Reservoir on the Colorado - New Mexico State Line near Arboles, Colorado. Below the Navajo Dam the San Juan River flows west through a narrow farming valley in the Colorado Plateau high desert, then west through the Navajo Nation, turning northwest near Shiprock. From there, it re-enters Colorado very near the Four Corners point where all four states touch - the only such place in the United States, before entering southeastern Utah. West of Bluff, Utah the river flows through the Comb Ridge and then through a series of rugged winding canyons, often over 1,500 feet in depth, in a remote portion of the Glen Canyon National Recreation Area, which was formed by Glen Canyon Dam on the Colorado River. The San Juan confluence with the Colorado is in San Juan County, Utah at an elevation of about 3,704 feel msl - some 4,261 feet lower than the East Fork run starting at Sand Creek on an average gradient of about 11.13 fpm, but do NOT be deceived - the river above Navajo Reservoir drops at a much steeper 17.3 fpm as the river drops some 891 feet in vertical elevation over about 51.3 miles.
This reach description begins at Dallabeta Park Access and continues about 17.2 miles to the US Highway 550 second crossing, the last practical access above the New Mexico state line, on a Class I to II whitewater run. A real gem on this trip is the very large natural gas midstream compressor station and processing plant located about 12.1 miles below the top of this reach. Other than that this run is mostly through wide open agricultural lands. Five access points(at least) offer opportunities for trips of various lengths, and it is mostly flatwater with small riffles and rapids occasionally, but MUCH less frequently that reaches above. You could continue acorss the New Mexico state line, but it is many miles to the next access point, so be prepared if you make that decision.
The run starts at an elevation of about 6,368 feet msl at Dallabeta Park in Durango and drops about 393 feet on a gradient of about 22.8 fpm, so there is a good current on a moderate slope. The river below this reach flows through Aztec, New Mexico toward the San Juan River confluence at Farmington near the Four Corners area where Colorado, Utah, New Mexico and Arizona all touch. Almost anybody can enjoy this most flatwater paddle in canoes, kayaks, rafts or SUPs, though the rapids that make rafing fun are all found upriver from here. The run is mostly remote though county roads are nearby, but with little traffic in this rural, open valley landscape.
La Plata County, Colorado, in the San Juan Mountains within the city limits of Durango. Nearby streams include the San Juan, Dolores, San Miguel, Uncompahgre, Lime Creek, Hermosa Creek, Rio Grande, Rio Chama and Gunnison Rivers, among many others in this area. The river runs through the San Juan National Forest.

Water quality is generally good and sometimes clear, though snow-melt cold. Minimum flows should be about 300 cfs and maximum flows for safe boating are about 3,000 cfs, though there are no major obstructions or hazards on this reach. The Durango Whitewater Park has some drop features that can definitely flip your boat, but recovery is generally quick and easy.
Generally, the optimum season is from late April through July, though the season may be extended or reduced according to the depth of the snow pack and/or recent local rains. In wet years it is possible to have year-round flow.
This reach of the Animas River has a few small riffles and rapids in the Class I to II range, but at normal flows (300 - 3,000 cfs) most will not pose significant hazards to most boaters. There are no known significant hazards on this reach of the Animas River (unless that compressor station blows up or leaks toxic vapors as you are in the area.)

There may be other available access points to this reach of the Animas River.
South Mineral Campground off US Highway 550 above Silverton is a public camping area; Purgatory, off US Highway 550 above Electra Lake and below Rockwood Box is a public camping area; There are numerous commercial campgrounds with tent camping, motels accommodations, supplies and other amenities on or near the Animas River.
