Sources of water

GRAVITY PIPELINE PLAN

The average annual project water supply would include 20,700 acre-
feet of storage water from Ruedi Reservoir, 3,900 acre-feet of direct
flows of the Fryingpan River, and 1,700 acre-feet of direct flows of
Cattle, West Coulter, and Mesa Creeks. The table below shows the aver-
age annual amounts of the suppJ.s' from each source for each project pur-
pose for the first 50 years and 100 years of project operation. The
amounts were estimated considering both the pattern of availability of
water from each source and the pattern of diversion requirements for each
purpose.

The total diversion requirement for lands to be provided with water
for irrigation and outdoor residential uses is estimated at an average
of 25,150 acre-feet annually. This includes about 24,450 acre-feet for
the irrigable area of 7,520 acres, based on a requirement of 3.26 acre-
feet an acre, and an additional 700 acre-feet estimated to be required
for the Colorado Mountain College area,. Approxima.teJ.s' 9,600 acre-feet
of the required supply is presentJ.s' available. With the additional
15,500 acre-feet provided by the project, essentially the full require-
ments of the lands would be met. The only shortages would be in areas
above the Landis Canal that would be served by exchange. The shortage
to these areas would average less than 3 percent annually and the short-
age to the total project area would average less than 1 percent. The
municipal and domestic supplies would be provided each year without
shortage.
