<br />(oJ Engineering analysIs has shown this shortage to average about 1.5
<br />acre-feet per acre in the West Divide Creek irrigation system. The
<br />addition of water storage facilities to the basin would permit late
<br />season irdgation demands to be met more often, reducing shortages and
<br />improving yields.
<br />
<br />About 1,950 acres are currently_ being, irrigated ,in the East
<br />Divide Creek basin; with an average diversion requirement of approxi-
<br />mately 6,000 acre-feet. The annual average flow available for diver-
<br />sion is 9,-470 acre-feet, which is 3,390 acre-feet more than the
<br />demand. Because there is no storage. in the basin the, annual irriga-
<br />tion shortage in the basin is about 1.75 acre,.-feet per al're.
<br />
<br />The average annual flow in the Marom Creek basin, from East,
<br />Middle and West Mamm Creeks combined, is 5,650 acre-feet. The
<br />existinll irdgated acreage 'in the basin is approximately 1,900 acres
<br />with an average annual diversion requirement, of, 5,930, ,acre-feet.
<br />Average annual irrigation shortages in this basin are sQmewhat higher,
<br />1.91 acre-feet per acre, t-han. those found in the East and West Divide
<br />Creek basins. The Mamm Creek basin includes Hunter Mesa,. which i:; pre--
<br />sently nonirrigated. Hunter Mesa, an area of about 4,700 acres, is
<br />presently used to raise dry-land ,wheat. Most of the Mesa is class 1,
<br />land which would be very suitable for ir,rig"tion, ,if an econom.ic an?
<br />reliable source of water were available.
<br />
<br />The Beaver Creek ,basin lies to the West of the Mamm Creek
<br />basin. Presently irrigated acreage in .the bas~n" which is on
<br />Taullhenbaugh Mesa, is about 1500 acres with, an aver,age, annual diver-
<br />sion requirement of 4,680 acre-feet. The average annual flow which,
<br />would be available for diversion and storage, is approximately ~,900
<br />acre-feet. Without storage in the basin, the average annual irriga-
<br />tion shortage is about 1.5 acre-feet per acre.
<br />
<br />Yank Creek is a tributary of Thompson Creek located to tl1e
<br />southeast of the West Divide area. Thompson Creek enters the Crystal
<br />River which Joins the Roaring Fork at Carbondale. Only a small amount
<br />of land is currently, irrigated in the. Thompson Creek, basin, and most
<br />~~. - - .
<br />,ot/' the irtigated land is served by water from the Crystal River. The ...----
<br />"average annual flow which could be regulated by -a storage site (Yank
<br />Creek Dam) near the Thompson Creek gaging station is 12,280 acre-feet.
<br />
<br />The Buzzard Creek and Owens Creek basins are in the
<br />Battlement Mesa Water Conservany District southwest of the West Divide
<br />Creek basIn. Owens Creek, which is tributary to Buzzard Creek, has an
<br />annual average ftow of 7,440 acre-feet_ The combined pnnual average
