In 2015, Will Stauffer-Norris kayaked about 70 miles of the Ji Qu, though only the last 40 miles were a first descent. The Ji Qu is the largest tributary to the main fork of the Mekong on the Tibetan Plateau (the Za Qu). This section is downstream of the rapid at the end of the 2011 expedition (http://www.shangri-la-river-expeditions.com/1stdes/mekong/jiqu2011.html). At the 2015 put-in 32.217555°, 95.657954°, elevation 13,100'), the river flow was about 15,000 cfs on June 7, declining to about 5,000 cfs on June 14 at the take-out (31.862097°, 96.291941°, elevation 12,200), with an average gradient of about 14 ft/mi (flows are estimates only, other data from Google Earth). There was one non-mandatory portage, a couple of class 4 rapids and several class 3 rapids, but otherwise river was a very busy class 2. The meander stretch at the end of this section of river is a great repeat run.
The meander stretch in the Goggle Earth image (covered with ice) is comparable to the Goosenecks of the San Juan State Park in southern Utah and hopefully will someday become part a Chinese provincial park. Last Descents River Expeditions provided Stauffer-Norris with transportation for this trip.
