<br />"The most recent estimate is made up as follows, and that is the
<br />estimate that I quoted from first: 18,131,000 acre-feet. These items
<br />go into that estimat8:
<br />"The virgin flow, or reconstructed flow, as it is sometimes called,
<br />at Lee Ferry, 16,271.000 acre-feet; the inflow, Lee Ferry to Boulder,
<br />1.060,000 acre-feet; the inflow from Boulder to Imperial Dam, 195,000
<br />acre-f8et.
<br />"The subtotal of those three items is 17,526,000 acre-feet.
<br />"Natural losses from Bould8r to Imperial Dam were estimated at
<br />about 1,075,000 acre-feet, which, subtracted from the above, gives
<br />you a virgin flow at Imperial Dam of 16,451 ,000 acre-feet.

<br />"Mr. LOWRY. The virgin flow of the Gila has b8en estimated
<br />at 1,300,000 acre-feet, which, added to the virgin flow at Imperial
<br />Dam, gives a virgin flow at the boundary of 17,751,000 acre-feet.
<br />To this figure ther8 has been added in our estimate for salvaged water
<br />below Boulder, 380,000 acre-feet. which makes a total of 18,131. 000
<br />acre-feet.
<br />"Senator MILLIKIN. Is that salvaged water as of the present time
<br />or estimated for the future?
<br />"Mr. LOWRY. That is an estimate of the future as further develop-
<br />ment takes place upstream.
<br />"Senator MILLIKIN. Over what period of time?
<br />"Mr. LOWRY. It is in terms of the development reaching ultimate
<br />conditions upstream, where we are using the virgin flow to start with,
<br />before anything was done on the river.
<br />"With respect to the above figure for salvaged water, no consider-
<br />ation is given to possible salvage that may be effected above Boulder
<br />Dam. Undoubtedly, as development in th8 upper basin takes place,
<br />there will be considerable savings in the natural losses. However,

<br />
<br />Mr. Lowry explained on pages 236 and 237 estimates of source of supply for
<br />
<br />Mexico as follows:
<br />
<br />"Mr. LOWRY. The Mexican allocation of 1,500,000 acre-feet
<br />is 8xpected to be made up as follows:
<br />"Return flow, 930,000 acre-feet; desilti ng water, 100,000 acre-
<br />feet; unused Gila flow, 100,000 acre-feet; making a subtotal of
<br />1. 130,000 acre-feet.
<br />* * *
<br />
<br />"Senator HAYDEN. I was just gOing to say that I am in very grave
<br />doubt about the amount of return water that you say will be available.
<br />You have got to show me.
