Water is <br />a necessity for the irrigation of the farm lands for the production <br />of crops. Practically all the problems identified herein are in' <br />some manner related to the quantity of water available, its quality, <br />and the effects of the use. andr:e-use of the water supply. The on- <br />going studies of the Agricultural Department in cooperation with <br />other Federal and State and local groups are oriented toward identify- <br />ing the problems and implementing plans for alleviating the problems. <br />The programs recognize the need to protect and enhance the wildlife <br />habitat and the environment, as well as to provide the social and <br />recreation needs of the people. <br /> <br />NEW MEXICO <br /> <br />Ongoing Studies. <br /> <br />1. Groundwater resources of the Rio Grande,Basin, a study by <br />the U. S. Geological Survey to delineate the principal areas in the <br />basin having the greatest potential for development of available <br />fresh and saline groundwater. The Rio Grande Basin is a water short <br />area. Within the basin are some fresh water resources which have <br />not been developed and saline water resources ,which may be economical <br />to desalt. Identification of such water reserves and their avail- <br />ability in relation to current supplies will be of material aid in <br />the utilization of these resources. <br /> <br />2. J" quantitative analysis of the groundwater system in the <br />Roswell Basin, Chaves and Eddy Counties, New Mexico. This is a <br />study by the U. S. Geological Survey in which the hydrologic en- <br />vironment in the Roswell Basin will be inspected and an ende~vor <br />will be made to determine quantitatively the forc~s and 'hydraulic <br />properties of the system so as to define the optimum yield of <br />water from the system. Development of groundwater for agricul- <br />tural, municipal and industrial use in the basin exceeds the safe <br />annual yield of parts of the basin. A large loss of head has <br />occurred which causes a movement of saline water into fresh-water <br />aquifers in some places, and a reduction in quantity and quality <br />of low flows in the Pecos..RiY.eI~_ <br /> <br />3. Evaluation of pumping effects of the Malaga Bend project <br />along the Pecos River, ~ddy County, New Mexico. This is an ongoing <br />study by the U. S. Geological Survey" the objec!Uve of which is to <br />evaluate the effectiveness of an experimental project to improve <br />the quality of water in the Pecos River by diverting brine inflow <br />in a short reach of the river. <br /> <br />40 <br /> <br />. i <br /> <br />.'.",.; <br /> <br />',::.. <br /> <br />-...;,;....,-..,....' <br /> <br />
