Abstract:

The Middle Rio Grande Endangered Species Act Collaborative Program (MRGESACP) contracted with the New Mexico Environment Department (NMED) Surface Water Quality Bureau (SWQB) to conduct water-quality monitoring and assessment to allow the MRGESACP to determine potential water-quality relationships that may affect Rio Grande silvery minnow (RGSM) recovery in the MRG.

Specifically, NMED conducted quarterly sampling of water and sediment, toxicity tests, and annual fish tissue collection and analysis at ten stations in the MRG as determined by the MRGESACP. The survey extended from Bosque del Apache, downstream of San Antonio, north to the Angostura Diversion Works, upstream of Bernalillo covering approximately 180 miles of river during each sampling event. This report provides details on the survey work completed between October 2006 and September 2007.
