<br />.. <br /> <br />. <br /> <br />. <br /> <br />,1 <br /> <br />'J <br /> <br />.'. <br /> <br />I'}'o")' r, -., <br />"'t..\J~ <br /> <br />The National Park Service is presently studying the flows <br /> <br />of the Gunnison diver through the canyon in order to conclude as to the <br /> <br />effects of the reduced flow upon the character of the monument. After <br /> <br />conclusions have been reached, it should be possible to make recommend- <br /> <br />ations as to the miniInum flDW that will be required to mainta~ as <br /> <br />nearly as possible the values for .Ihich the Monument is noted. <br /> <br />Under the present proposed plan for operation of the <br />Gunnison-Arkansas Project, the total annual flow of 36,000 acre feet, <br /> <br />or an average flow of about fifty sec.ond,f.ee.t.! is contemplated <br /> <br />through the Monument. The stream flow for the period October 1, 1943, <br />to September 30, 1946, below the present Gunnison Tunnel which supplies <br /> <br />water to the Uncompahgre Project, as recorded by the Water Resources <br /> <br />Branch of the Geological Survey, is shown on a graph included in the <br />report with other charts and maps far Group B. The minimum flow re- <br />corded was about :t'ifty:<secondfeetoJ. This minimum fl"w, comparable <br />to that contemplated under the proposed plan of operation of the project, <br /> <br />was reached for a brief period during April 1945. The river was also at <br /> <br />or near the minimum flow mark for brief periods in August, September, <br /> <br />and October during the 1943-46 period. <br /> <br />2, These six sites lie in a region Df outstanding <br /> <br />scenery, ranging from the sp,",ctacular Black CanJion of the Glli"J.nison to <br /> <br />the rugged peaks of the Continental Divicie, ,'here excellent opportun- <br /> <br />ities for outdoor recreation exist. <br /> <br />3. From a study of the proposed plans of o~eration for <br /> <br />the 12-year period, 1930-1941; it is apparent that, ~hi1e some of <br /> <br />21 <br />
