<br />southeast a distance of about 27 miles. In addition to surplus water from the Tomillo Canal, <br />HCCRD obtains water from the Hudspeth Feeder Canal No.1, the Tomillo Drain, and the Rio <br />Grande through the Alamo heading and Alamo Canal. At least 7 laterals are supplied by the <br />Hudspeth Main Canal. Three reservoirs have been constructed in the HCCRD service area to <br />provide storage and regulation for the water obtained from EPCWID. According to J. Cline, <br />these reservoirs have a combined capacity of about 4,500 acre-feet in 1996. <br /> <br />Rio Grande Outflow <br /> <br />The outflow in the Rio Grande from this portion of the basin is shown by the records for <br />the stream gaging station at Fort Quitman. Table 2-8 summarizes these records and shows that <br />the outflow averaged 271,870 acre-feet during 1889-1995 and ranged from only 1,663 acre-feet <br />in 1965 to 1,550,230 acre-feet in 1905. Figure 2-7 is a bar chart showing the annual flows at <br />Fort Quitman during 1889-1995 and the ten-year summary average of annual flows. These <br />flows were small during the 1950's, 1960's, and 1970's, but have increased significantly during <br />the late 1980's and 1990's. <br /> <br />r. ,; ,., . 1 <br />'J... j ~..: J.. <br /> <br />2 -20 <br />
