La Morita rapid on the Rio Aros, Dec. and July comparison

Photo comparison of La Morita rapid on the Rio Aros in both December 2011 and July 2012. December flows were high for the time of year and July flows were near average.

Flows in late spring and early summer are so low that the run in the foreground is completely non-existant (dry). What flow there is on the other side of the river moves between and mostly under the house-sized boulders.

Rio Sonoyta mapThe Rio Sonoyta, despite grazing across the watershed, agriculture, groundwater pumping, and the incredible dry nature of the region, still has perennial flow in stretches west of the town of Sonoyta.
