  <dc:description>Approximately 40 percent (about 600,000 people) of the total &#13;
population of New Mexico lives within the Middle Rio Grande Basin,&#13;
which includes the City of Albuquerque. Ongoing analyses &#13;
of the central portion of the Middle Rio Grande Basin by the U.S. &#13;
Geological Survey (USGS) in cooperation with the City of &#13;
Albuquerque and other cooperators have shown that ground water in &#13;
the basin is not as readily accessible as earlier studies &#13;
indicated. A more complete characterization of the ground-water &#13;
resources of the entire Middle Rio Grande Basin is hampered by a &#13;
scarcity of data in the northern and southern areas of the basin.&#13;
&#13;
     The USGS Middle Rio Grande Basin Study is a 5-year effort by &#13;
the USGS and other agencies to improve the understanding of the &#13;
hydrology, geology, and land-surface characteristics of the Middle &#13;
Rio Grande Basin. The primary objective of this study is to improve &#13;
the understanding of the water resources of the basin. Of &#13;
particular interest is to determine the extent of hydrologic &#13;
connection between the Rio Grande and the Santa Fe Group aquifer. &#13;
Additionally, ground-water quality affects the availability of &#13;
water supplies in the basin. Improving the existing USGS-&#13;
constructed ground-water flow model of the Middle Rio Grande Basin &#13;
will integrate all the various tasks that improve our knowledge of &#13;
the various components of the Middle Rio Grande water budget. Part &#13;
of this improvement will be accompanied by extended knowledge of &#13;
the aquifer system beyond the Albuquerque area into the northern &#13;
and southern reaches of the basin. Other improvements will be based &#13;
on understanding gained through process-oriented research and &#13;
improved geologic characterization of the deposits. The USGS will &#13;
study the hydrology, geology, and land-surface characteristics of &#13;
the basin to provide the scientific information needed for water- &#13;
resources management and for managers to plan for water supplies &#13;
needed for a growing population. &#13;
&#13;
     To facilitate exchange of information among the many USGS &#13;
scientists working in the Middle Rio Grande Basin, yearly technical &#13;
meetings are planned for the anticipated 5-year study. These &#13;
meetings provide an opportunity to present research results and &#13;
plan new field efforts. This report documents the results of &#13;
research presented at the first technical workshop held in Denver, &#13;
Colorado, in November 1996.&#13;
&#13;
     The report is organized into this introduction, five chapters &#13;
that focus on USGS investigations in progress in the Middle Rio &#13;
Grande Basin, and three appendixes with supplemental information. &#13;
The first chapter provides an overview of the USGS program in the &#13;
basin. The second chapter describes geographic data and analysis &#13;
efforts in the basin. The third chapter details work being done on &#13;
the hydrogeologic framework of the basin. The fourth chapter &#13;
describes studies on ground-water availability in the basin and is &#13;
divided into three areas of research: ground-water/surface-water &#13;
interaction, ground-water flow and aquifer properties, and &#13;
recharge. The fifth chapter is devoted to an overview of New Mexico &#13;
District Cooperative Program studies in the basin. Finally, the &#13;
appendixes list publications and presentations made during the &#13;
first year of the study and 1996 workshop attendees. The report &#13;
concludes with a list of selected references relevant to the study.&#13;
&#13;
     The information in this report presents preliminary results of &#13;
an evolving study. As the study progresses and individual projects &#13;
publish their results in more detail, the USGS hopes to expand the &#13;
scientific basis needed for management decisions regarding the &#13;
Middle Rio Grande Basin.</dc:description>
