MR. STAPLETON:

MR. BITTINGER:

Experience with making such estimates has
shown that a range of plus or minus 10% is
reasonable so the data presented here are given
on that basis. The following tabulation summar-
izes the study:

Estimated Yearly Consumptive Use (acre-feet I
per year): On the Rio Grande - cotlsumptionin
Rio Grande County 9,500 to 11,600; in Alamosa
County 6,300 to 7,800; and in Conejos County
10,500 to 13,000. On the Conejos River, of
course that is all in Conejos County - 7,400 to
9,000. On the San Antonio, which is also all
in Conejos County - 700 to 800. This makes a
cumulative total all together of 34,500 to
42,100. '

The report goes on to say:

'In considering what part of the estimated
water use might be salvaged through a program of
vegetation ~ont;ol, past expe~ience provides
very little guidance. For tpe purpose of an
estimate, a conservative figUre would be 5~~.
On this basis 17,250 to 21,000 acre feet of
water might be estimated to be salvagable
annually.

In concluding, the writers wish to empha-
size that the data presented here are estimates
based upon the inspection of aerial photographs
and the application of water use coefficients
derived on purely empirical grounds. The esti-
mates are thought to be reasonable and conserva-
tive. On-site studies along the Rio Grande in
New Mexico by the USBR have developed water use
data which are somewhat higher than those used
here. '

Mr. Bittinger is here in case somebody
wants to ask him some qUestions."

"Are there any questions on that report?
Mr. Bittinger, would you like to amplify it in
any respect?"

"Not unless there are questions."
