Field Research Slideshows

This is a research trip in 2012 to the Lower Canyons, a 72 mile stretch of the Rio Grande. It is referred as a "seepage run," because it is designed to measure discharge and basic water chemistry at as many locations as possible in order to determine where the bulk of the spring inflow to the river is located. Scientists from Sul Ross State, the National Park Service, the Texas Parks and Wildlife Department and U.S. Fish and Wildlife took part in the trip. Also collected was a cross section data for aquatic habitat studies.

This is the Boquillas Canyon float trip during the flood in the fall of 2008, where river levels were in the vicinity of 30,000 cubic feet per second. The trip took about six hours to complete. At normal river levels of about 200 to 300 cfs, the trip takes three days. There were no rapids, but there were numerous whirlpools that developed on the surface of the water. There were also huge rafts of river cane (arrundo donax) that had been ripped up from near the river.
