<br />. <br /> <br />. <br /> <br />. <br /> <br />001875 <br /> <br />s~tl't. the main oonduit from the Navajo River to the Azotea Portal <br /> <br />should be designed to carry approximately 1,000 cfs. For June, 1957, <br /> <br /> <br />the month of greatest spill, the full diversion of 27,470 acre-feet <br /> <br /> <br />from the Rio Blanco left a capacity of 5,200 acre-feet in the Little <br /> <br /> <br />Navajo to Navajo River conduit, but 10,120 acre-feet filled the <br /> <br /> <br />remaining capacity in the conduit below Navajo and 17,350 acre-feet <br /> <br /> <br />had to be spilled at the Rio Blanco diversion. If the conduit below <br /> <br /> <br />Navajo River were enlarged to 1,000 cfs it would increase its carry- <br /> <br /> <br />ing capacity by 8,900 acre-feet in the month of June. <br /> <br /> <br />If the capacity of the main conduit below. Navajo River is <br /> <br /> <br />increased by 150 cfs, the spills of divertible water during the study <br /> <br /> <br />period 1942 to 1957 would be reduced from 49,700 acre-feet to <br /> <br /> <br />13,534 acre-feet. Spills of Rio Blanco divertible water would occur <br /> <br /> <br />in only two years instead of seven years. <br /> <br />- 16 - <br />
