The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
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.
Elements of the comprehensive plan now include planning for water resources that must address the currently available surface water, groundwater, and effluent supplies and provide an analysis of how the future growth projected in the county plan will be adequately served by the legally and physically available water supply. This is the first study to be issued as part of the Water Resources Element and identifies a number of measures that can be taken to conserve water, including measures that can be taken by Pima County in the form of ordinance adoption.
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.
Brings together the findings of previous reports and suggests policies to address water quality issues in Pima County.
Includes the Pima County staff response to Tucson Water Comments (May 16, 2001) and An Evaluation of Hydrologic and Riparian Resources in Saguaro National Park (March 2001). Groundwater withdrawals pose a threat to middle basin riparian areas.
Argues that the canons of evidence that apply to artifactual evidence of prehistoric behavior patterns are sometimes distinct from those that apply to non-artifactual evidence, and the logic and archaeological value of the latter is not less simply because it is different. The essay is intended to instruct and sensitise archaeologists to this issue as much as it is to allay concern that the pollen evidence for Archaic maize cultivation at the Koster site may not be credible. 49 p.
