<br />height, 16.55 ft or 5.044 m), from rating curve extended above 2,000 ft3/s (60 m3/s)
<br />on basis of previous rating curve defined to 27, 000 ft3/s or 760 m3/s.
<br />
<br />Remarks. --Total capacity of the 4 reservoirs is 1,755,000 acre-ft (2, 160 hm3), divided
<br />as follows: Roosevelt Lake, 1,382,000 acre-ft (I, 700 hm3); Apache Lake, 245,000
<br />acre-ft (302 hm3); Callyon Lake, 58,000 acre-ft (71. 5 hm3); and Saguaro Lake,
<br />70,000 acre-ft (86. 3 hm3). Dead storage negligible. Dams forming these reservoirs
<br />were built as follows: Roosevelt, 1905-11; Horse Mesa, 1924-27; Mormon Flat,
<br />1923~26; and Stewart Mountain, 1928-30. Since 1910, spill over Roosevelt Dam
<br />because of capacity or near-capacity storage has occurred only during the following
<br />periods: Apr. 15 to June 21, 1915; Jan. 19 to May 30, 1916; Apr. 21 to June 7, 1917;
<br />Feb. 17 to June 3, 1920; Apr. 13 to July 24, 1941; Dec. 30, 1965 to Jan. 10, 1966;
