Fort Lowell was a supply base for the United States Army “Apache Campaigns” between 1873 and 1891. Following abandonment of the fort in 1891, settlers moved in and used some fort buildings as residences, or stripped the buildings of useful materials. By the 1930s, much of the fort had fallen into disrepair or had been sold off. Eventually, the City of Tucson acquired a large portion of the old fort which became what is today’s “Fort Lowell Park.” A 5.2 acre (“Adkins”) parcel of the former fort containing several original adobe buildings was still in private ownership, and the 2004 County bond election passed a proposal to acquire the land and preserve the historic resources.

Pima County's Cienega Creek Natural Preserve surface water and groundwater monitoring project. This report summaries PAG's groundwater and surface water monitoring between July and June each fiscal/ monitoring year. The report contains monitoring methodology, comprehensive maps, and graphs of trends for surface flow volume, wet-dry flow lengths, groundwater levels and water chemistry. It also contains information on drought, erosion and repeat photography.

Pima Association of Governments updated a portion of the Water Usage Along Selected Streams in Pima County, Arizona, which PAG created in 2000. The updated report and datasets show current potential water usage in these critical areas. Deliverables include the shapefiles, spreadsheets and maps that accompany this memorandum. The purpose of this report is to provide updated information about the location and pumping history of wells located in Pima County near shallow groundwater areas, generally located near drainages.

This report summarizes published reports and public datasets pertaining to the subsurface hydrology of Sopori Basin. It includes descriptions of the hydrogeology of the basin, recharge, the number and type of wells, well installation frequency, changes in water levels through time, shallow groundwater areas, groundwater pumping, grandfathered irrigation rights and water quality. Data sources and limitations also are discussed. This report is intended to provide a broad understanding of the groundwater conditions in Sopori Basin based on existing information.

The purpose of this report is to present the data gathered to date in the Santa Cruz AMA in support of the management goal and groundwater modeling effort. This report presents groundwater and surface water monitoring data, USGS stream gaging data, effluent data, gravity studies, historical water use and water quality data for three distinctive stream reaches of the Santa Cruz River.

The purpose of this project was to compile information on groundwater withdrawals and surface water diversions near perennial streams, intermittent streams, and shallow groundwater areas previously identified by PAG for the SDCP. The information could be used to prioritize future investigations of potential impacts of these withdrawals and diversions on riparian and aquatic habitats for the SDCP.

This document and the Geographic Information System file that is now a part of the County library of over 1000 coverages, gives the scientific community access to mapping that better differentiates perennial, ephemeral and intermittent watercourses, and provides more comprehensive coverage of shallow groundwater sources. This data is significant because riparian habitat is one of the most important and least protected of the habitat types in Pima County.

This update of Arizona’s Statewide Comprehensive Outdoor Recreation Plan is in accordance with the provisions of the Land and Water Conservation Fund Act, which was enacted in 1964 to encourage the provision of greater recreation opportunities for American citizens. Arizona receives annual congressional appropriations from LWCF, administered through the Arizona State Parks Board to fund state and local government sponsored outdoor recreation projects.
