Abstract:

Reconnaissance of portions of the Middle Rio Grande is mandated by Reasonable and Prudent Alternative Element C of the 2003 Biological Opinion (U.S. Fish and Wildlife Service 2003), known as "RiverEyes." RiverEyes monitoring must be performed when flows are less than 300 cubic feet per second (cfs) at San Acacia Diversion Dam. RiverEyes provides current information on river flows that allow action agencies to react quickly to rapidly changing conditions on the river, facilitate coordination among the agencies to prevent unexpected drying, and prepare for Rio Grande silvery minnow (Hybognathus amarus) rescues.

Hydrologic conditions in the Middle Rio Grande were systematically monitored from June 15 to October 31, 2010, to document spatial and temporal effects of low discharge flow regimes during periods when discharge was less than 300 cfs over San Acacia Diversion Dam.
