OPERATION

..

The out look for water during the winter and early spring was most
encouraging. With the largest carry-over of storage water that had oocurred
for several years, and the promising reports from the water shed, there
seemed to be no doubt that there would be almost a normal supply of water.

,--

T>>e canals and ditches were put in shape to operate to capacity.
As the spring advanced and' it fuecame evident that the runoff would not be
as large as expected, reports to that effect were sent out to the waterusers.
The first notice was to the effect that there would probably be about 1.60
acre feet per acre available for delivery to the land. Later a survey of the
water shed was made and it was finally determined that only about 1,45 acre
feet per acre could be delivered.

Naturally the water users would like to know as early as possible what
wnount of water can be delivered, But that can not be definately determined
until after the spring run off has occurred. The storage is a~a0 adversely
- effeQted by dry spring weather, If the weather during the spring is dry and
windy there is not only a gre~ter loss through e~aporation but also greater
demand and use of water by senior appropriators, and consequently.less of the
spring run-off is available for storage,

')

Water allotments to the different. divisions of the project were
made on June 22, the allotment was based on the amount of water th~t had
been used to that date plus the amount of water in storage and an estimate
of the inflow for the balance of the season.

.

In calculating the division of water between the different divisions
of the project, the :ccreage to be irrig:cted and the canal efficiency are the
governing factors.

The allotment to project lands of both natural flow and storage
was as follJws'in acre feet,

The allotment fDr the Pathfinder Irrigation District includes the
water stored in Lake Minatarc and Lake Alice,

In additiDn the above, an allotment of 109,140 acre feet was made
to 313,900 acres of land under Warren "ct Contr'Ccts.

The first water was turned into the head Df the Interstate canal
on April 19t4. The beginning was delayed because of a blizzard which occurred
on .lpl'U 16.
