as potatoes and sugar beets. At times of extreme shortage runs of 
5 to 8 days are made, at intervals of 5 to 8 days, and 20 to 30 inches 
are delivered to the share. 
Kecords kept include frequent readings of all reservoir gauges, 
from which the available supply may be determined ; records of dis- 
charge of the main canal at the head and of the various mountain 
ditches of the system ; records of water delivered to each stockholder, 
and records of all water received or delivered in exchange. The 
records of delivery are on cards and show for each user each day of 
the season the number of shares he drew water on, the rate in inches 
per share, and the depth over the weir. 
GREELEY CANAL NO. 2. 
The Greeley Canal No. 2, known also as the Union Colony Canal 
No. 2, or the Cache la Poudre Canal, was built by the Union Colony 
at Greeley. Preliminary work was done in 1870 and the first con- 
struction was completed in 1871. Enlargements were made in 1874 
and 1877. In 1878 the Cache la Poudre Irrigation Co. was organized 
by the farmers under the canal to take over control from the colony, 
and a large sum was spent in improving the headworks and in better- 
ing the alignment of the canal. The present company, the New Cache 
la Poudre Irrigation Co., was organized in 1890 to undertake various 
improvements of the system. The company has a capital stock of 
$100,000 divided into 2,500 shares of a par value of $40, of which 
2,496 have been issued. Each of the original rights is represented 
by 8 shares of the present company. In 1916 rights sold for $2,800, 
which is equivalent to an increase of 900 per cent in value. 
The entire cost of operation and ordinary maintenance of the 
canal has lately been met by charges of the company for carrying 
reservoir water, and assessments were levied on the stock only for 
special expenses. Thus in 1916 current expenses were $6,736, while 
tolls for carrying reservoir water amounted to $7,961. The average 
cost of operation and maintenance is at the rate of approximately 
20 cents per acre irrigated. 
The main canal heads in section 11, T. 6 N., E. 68 W., and ends 
26 miles below at Lone Tree Creek, but an 18-mile extension tails in 
Crow Creek. At the head of the canal it is 34 feet wide on the bot- 
tom, carries water to a depth of 4 feet, and is on a grade of 3.2 feet 
per mile. The maximum head carried during 1916 and 1917 was 
558 second-feet. There are 40 companies owning and operating the 
larger laterals and the total length of laterals is estimated to exceed 
300 miles. 
The water rights of the company are shown in the tabulation on 
page 15, and the area irrigated in 1916 in Plate XII.
