Nambe Falls Dam


Nambe Falls Dam,  a concrete and earth embankment structure is 150 feet high. Construction began on June 13, 1974 and was completed on June 28, 1976. The storage reservoir provides supplemental irrigation for the Pojoaque Valley Irrigation District and the pueblos of San Ildefonso, Nambe, and Pojoaque.


The dam is located about 300 feet upstream from Nambe  Falls which forms the sharp break between the Sangre de Cristo mountains  on the east and the Espanola Basin on the west. The dam is situated in  a 500-foot-long southwesterly trending gorge. The concrete arch dam  and thrust block are founded on a northeasterly trending fault slice of  Precambrian Embudo granite complex (consisting of granite and granite  gneiss with intrusive pegmatite and inclusions of schist and gneiss)
