lEEIGATION IN NORTHERN COLORADO. 35 



ducing a fund of $60,000. Of this, $20,000 is to cover interest charges 

 on indebtedness and $10,000 goes into a sinking fund. Ordinary- 

 operation and maintenance costs are covered by the remaining 

 $30,000, which is at the rate of approximately 65 cents per acre 

 irrigated. 



The Water Supply & Storage Co. system includes 11 reservoirs 

 with an aggregate capacity of 26,000 acre-feet, 4 canals tapping other 

 watersheds and diverting water into the Cache la Pouclre, the Lari- 

 mer County Canal, and an interest in the Jackson Ditch. 



The Larimer County Canal is the distributing canal for the system 

 and also supplies the lower reservoirs of the system. It heads in 

 section 13, township 8 north, range 70 west, and extends eastward 

 75 miles to Owl Creek, into which it tails. The area irrigated is 

 shown in Plate XL The canal is 24 feet wide on the bottom, has 

 a grade ranging from 1.32 to 3.16 feet per mile, and will carry 600 

 second-feet. There are about 50 laterals, with length of 150 milas. 



At the head of the Cache la Poudre River the company owns four 

 ditches which divert water from other sheds and turn it into the 

 Cache la Poudre to be stored in Chambers Lake or diverted below 

 into the Larimer County Canal. The Skyline Ditch intercepts 

 water from' tributaries of the Laramie River, the Cameron Pass 

 Ditch diverts from the Michigan River shed, and two ditches divert 

 the headwaters of the Grand River. For carrying this foreign water 

 in the channel of the Cache la Poudre the water commissioner de- 

 ducts 5 per cent for losses in transit. 



The company owns an interest in the Jackson Ditch, acquired by 

 purchase from the Larimer & Weld Reservoir Co., and a further 

 interest was obtained by an exchange arrangement with individuals 

 under the Jackson Ditch whose farms lie partly above the ditch. 

 Contracts covering this exchange arrangement provide that the 

 Water Supply & Storage Co. acquires a definite amount of stock of 

 the Jackson Ditch, and the water secured on it is tailed into Long 

 Pond. In exchange the individual acquires the right to an equal 

 •amount of water, less a small per cent for loss, from the Larimer 

 County Canal throughout the season for his high land. The Water 

 Supply ■& Storage Co. benefits by the arrangement because it receives 

 the Jackson water throughout the season constantly, while the de- 

 mand on the Larimer County Canal is intermittent. 



Three of the reservoirs of the company, Chambers, Lost, and Lara- 

 mie Lakes, with an aggregate capacity of approximately 7,000 acre- 

 feet, are located at the head of the Cache la Poudre and in addition 

 to storing water of the Cache la Poudre may be used to hold up 

 foreign water brought over from other sheds. 



Of the lower reservoirs Black Hollow, with a capacity of 5,760 

 acre-feet, is on the line of the canal about 25 miles from the tail of
