San Agustin & Alamosa Creek Study

The AMP initiated a regional hydrogeologic study of the Plains of San Agustin and the Alamosa Creek Valley in October 2009 in response to questions and data needs from state agencies (NM OSE/ISC, NM EMNRD Mining and Minerals Division, and NMED). The issues relate to groundwater availability in the San Agustin basin and possible effects of mineral resource development on water quality in ecologically and culturally sensitive Warm Spring and Alamosa Creek near Monticello. The project will provide impartial hydrologic information to the State’s regulatory agencies, industry and public about the aquifers and possible hydrologic interconnection with Alamosa Creek and adjacent aquifers in the Rio Grande Valley. Completion of report is expected in December 2014.

Funded by the Aquifer Mapping Program, the Bureau of Geology, the National Cooperative Geologic Mapping Program (STATEMAP), Healy Foundation and the NMOSE.
