Judging from Google Earth images, the water level in this reservoir is normally rather low.
"San Carlos Reservoir is located at Coolidge Dam in Arizona and was constructed in 1928 by the Bureau of Reclamation for irrigation purposes. It is the largest reservoir in the San Carlos Irrigation Project, covering an area of 19,500 acres and with a capacity of up to 1,315,400 acre-feet of water." [

"The dam is 250 feet high and provides over 900,000 acre-feet of storage, which is used to irrigate over 100,000 acres. The dam consists of three reinforced concrete dome arches with buttress supports. The dam includes two uncontrolled spillways which each contain three 50-foot-wide bays and inoperable 50-foot-wide by 12-foot-high drum gates. The outlet works consists of two 250-foot-high intake towers with 8-foot-diameter conduits extending through the dam." |

I had to go back to 1998 to find a relatively full reservoir.

The spillways have been used only in 1993.
Are they using the outlet pipe above, but the outlet is under water?
