In the former study it Nas assumed there would be an exchanee of,~irect

flow water up stream even as far as the 3essemer cnnal. However, detailed

studies indicated such direct flow water available for exchanE-e would be very

.....
~ unfirm, ~oin~ to one canal at one time and another at another time in order of
~
~ priority. The exchanGe water would be so uncertain that no upstream canal

could chan~e its present irripation pro~ram either as to the use of water or as

to the plantin~ of crops.

For this reason the present study contemplates that the area benefited

shall not extend above the Fort Lyon canal, and that the benefit to this canal

system shall be derived from the transfer to that system of the water formerly

stored in the ~reat Plains reservoir by the A~rr;ity canal system. It was assumed

that this water will be re!Culated in the existing Horse and Adobe Creek

reservoirs, and in the ~ueens reservoir, which is one of the Great Plains

,

reservoirs, the former operations of the Ilorse and Adobe Creek reservoirs

being taken into consideration. In the assumed operation there will be

supplied to the Amity canal from Caddoa reservoir an amount of water equivalent

to that formely received from the Breat Plains reservoir, in addition, of

course, to sufficient additional water to take care of the assumed defioiency

under that canal.

The period of years covered by the study includes four of the years of

the hi~hest run-off on the stream, namely, the years 1914, 1915, 1921 and 1923.

There has been some question whether the reservoir, over a lon~er period, would

operate ..i th no more shortar,es than olould have occurred had it operated only

during the period covered by the study!
