A tenaja is a water basin or retention area. (From the Spanish, tinaja, which is a large clay pot/vessel.) The term usually implies a natural or geologic cistern in rock which retains water. They are often created by erosional processes within intermittent streams.
Before European settlers came to America, tenajas were a valuable source of water for early Native Americans traveling in the desert areas of the Southwest. Today, tenajas are an integral part of sustaining life in the arid Southwest. For example, tenajas at the Santa Rosa Plateau in southern California allow western pond turtles, California newts and red-legged frogs to survive through dry summer months.[1]
