Small additional benefits of Purgatoire f10woccur to the Amity Canal

~;.

during the low water period of November to March inclusive. A rough analysis

';;

in acre-feet by months for the period 1921 to 1925 wi,ll be found on p.10. This

analysis shows that the wint er benefUs are relatively small beCa\Hle there is

always surplus up-river flow passing LaJun.ta during the wint'lr months, and

con.sumptive demands by other canals between LaJunta and Lamar lIre also small.

Sumnarizing, we have the following diversions by the ~1Y-9~F~l, in

Inclusion of winte!' diversions from Purgatoire flow may raiee the total bene-

fits from the Purgatoire flow by 1,000 acre-ft. in average years, making a

total yearly benefit from the Pur!J3.toire River of not to exceed 12,000 acre-ft.
