The project would cause the Rio Grande River to <br />become a continuous live stream throughout the Rio Grande Gorge, an area <br />which is a part of the National Wild and Scenic Rivers system. Much of <br />the Closed Basin area is now virtually sterile as a result of salt accu- <br />mulations. The project will reverse the salt trend and permit the re- <br />establishment of native vegetation and native wildlife. Unlike many <br />projects of this nature, no resources would be irreversibly committed. <br /> <br />An additional beneficial effect will be the sustained flow in <br />the channel of the Rio Grande downstream from Alamosa. This continuous <br />flow will reduce siltation and aggradation in the channel, a condition <br />which has resulted from upstream diversions. This continuous flow from <br /> <br />-2- <br />
