Apache County is required by state law to prepare a comprehensive plan “to conserve the natural resources of the county, to insure efficient expenditure of public funds, and to promote the health, safety, convenience, and general welfare of the public.” The planning process is structured to emphasize public involvement and incorporate comments, ideas, and direction of the public into the plan. This plan strives to create strong and vibrant communities within Apache County by encouraging orderly development.

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.
