Water as we talk in terms of growth, habitat protection and it is probably the limiting natural resource in this valley and region. Sustainability was drafted into the groundwater proposal in 1980 and it required all of the Active Management Areas of Arizona to achieve a safe deal within 45 years after balance of plan. The groundwater code had a very unique way to meet the assured water supply requirements. Before you can subdivide property you have to show that there is adequate water supply for 100 years.

Takes a comprehensive view of ironwood habitats in both the United States and Mexico, evaluating the ecological and cultural resources supported by the ancient ironwood tree. The study provides an overview of the history and ecology of desert ironwood, and a discussion of the binational research effort undertaken to produce the report.

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.
