Provides a brief summary of a compilation of resource investigations that have been submitted so far, to help develop the SDCP within the watershed planning area of the Tortolita Fan.
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.
Conservation of the Tortolita Alluvial Fan landscape has been promoted by Pima County and Town of Marana over the past two decades. An interdepartmental team was formed to evaluate flood and debris flow hazards and the potential to create an expanded Tortolita Fan Preserve. This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.
Reports on the development of a reconnaissance level numerical groundwater model of the Davidson Canyon and Cienega Creek watersheds. Includes recommendations for data that must be collected prior to completing environmental analyses for the proposed project.
