Letter to Carl T. Hayden regarding a water-power bill in effect for the Grand Canyon.
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.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
Summarizes four documents that reflect some of the work that Pima County and Department of Interior staff, along with the science and Geographic Information Systems technical teams, have created to develop the biological component of the Sonoran Desert Conservation Plan.
Pima County Department of Transportation's Technical Services Division maintains GIS hardware, software, and databases with skilled personnel and has applied TIS technology to the SDCP, adapting, creating or acquiring over 1000 data layers for use in the Plan. Metadata has been developed for some of these layers.
