Forests and woodlands also comprise <br />a significant portion of the Region (17%). About four percent of the land <br />is used for agriculture and farming, of which about half is irrigated. With <br />regard to ownership, most (70%) of the land is privately owned or owned by <br />state or local municipal governments, twenty-seven percent is in federal <br />ownership, and three percent is Indian land [5]. <br /> <br />Genera 1 descri pti ons of the geology, cl imate, demography, economy, 1 and <br />use, natural resources, and environment of the study area are contained in <br />the WRC National Water Assessment report for the Rio Grande Region [5]. <br /> <br />SUBAREA DELINEATIONS <br /> <br />The Water Accounting Unit (WAU) is the smallest hydrologic subdivision <br />used for analysis in the 13(a) assessment study. These subdivisions were <br />established by the U.S. Geological Survey (USGS) to represent natural and <br />manmade stream drainage areas for purposes of managing the National Water <br />Data Network [6]. <br /> <br />In the Rio Grande Region, thirteen WAU's are designated. These are <br />identified on the map of the Region in Figure 2, and they are listed in <br />Table 1. <br /> <br />0109 <br /> <br />5 <br />
