In the early 1990s, a study of the Tanque Verde Creek by Dr. Julie Stromberg and others described the relationship between the depth to groundwater and the health of the mesquite woodland habitat in the area. This report revisits the Stromberg study to describe variations in groundwater levels since the report was completed early last decade. They identified around 3,000 acres of riparian vegetation in the Tanque Verde-Agua Caliente shallow groundwater zone.
The final version of the report issued in early 2001. County staff responded in writing to clarify misunderstandings in the letter by Tucson Water. Pima County will continue to assess and look for ways to contribute to the protection of the resources in the Tanque Verde area.

Arivaca, located on the southern border of Pima County, is one of the few remaining riparian areas in southern Arizona. This report presents collected data, shows how the Arivaca area relates to the SDCP, and makes recommendations on how the plan could address pressing groundwater issues in the Arivaca Valley.
