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.

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 paper provides a capsule perspective on the lessons economists have learned from investigating growth and income gaps across countries. After providing the lessons for growth and development across countries, the paper asks whether these lessons can be extended to growth and income differentials between regions or states of the United States. It should be stressed that applying to regional growth what is known about country growth is partly untested at this time, and hence merely suggestive.

This paper explores whether a knowledge economy explanation for economic growth seems to fit with the growth experience of the Sunbelt during the 1990s. The issue is addressed through analysis of two different datasets. First, the education and income characteristics of the people moving to the Sunbelt region are examined using migration data from the 2000 census. Then we look at the link between the knowledge economy metric of the share of college educated adults and economic growth in the Sunbelt in the 1990s using data for 116 Sunbelt MSAs.
