32 BULLETIN 1026, U. S. DEPAETMENT OF AGRICULTUEE. 



canal are made through Powell gates which are kept locked so that 

 they may be raised or lowered only hj the ditch rider. The water 

 delivered is measured over a rectangular weir, the depth over the 

 weir being determined from tables carried by the rider, which 

 show the depth to be carried over any crest length from 1 foot to 12 

 feet for any number of rights from | to 68. In general, the water 

 supply from the river is prorated among the users in accordance 

 with the number of shares of stock which they hold, and to get the 

 water to which he is entitled the user has only to notify the rider of 

 the main ditch, or else the rider of the lateral from which he gets 

 his supply, who will in turn notify the rider of the main canal. In 

 times of very short supply a system of rotation of the supply between 

 sections of the canal is instituted to avoid the wasteful practice of 

 prorating a small supply. The company recognizes and encourages 

 the practice of rotation of water among users, and the stockholders 

 may have their water delivered to any lateral upon request. No 

 records are kept of the delivery of water received on direct appro- 

 priations. Reservoir water and water received on direct appropria- 

 tions are not run at the same time, and usually after the running of 

 reservoir water is started the small amount received on appropria- 

 tions from the river goes to make up losses in the canal or to pay 

 for water advanced to the canal earlier in the season by the Windsor 

 Reservoir. 



Considerable care is used in the distribution of reservoir water, 

 and complete records are kept by the secretary of the company. 

 Before any water is delivered all carriage charges must be paid 

 and credit entered on the books of the secretary. The delivery 

 record of each user occupies one large sheet, 8 by 27 inches, of a 

 loose-leaf book. Heading each sheet is the name of the owner, 

 with a space in which may be entered the name of the tenant. 

 At the left of the sheet there are blanks opposite the names of the 

 various reservoirs in which may be entered the total nimiber of 

 rights of each with which the user is credited. Below are columns 

 in which any debits or credits may be entered during the season. 

 The right side of the sheet is devoted to records of delivery, with 

 columns for every day from July 15 to September 15 and others 

 in which are entered the name of the person ordering the water 

 delivered and the lateral to which it was delivered. Under the dates 

 are entered the numbers of " rights " delivered on that date. While 

 this form of record is too large to be handled conveniently, the 

 advantage of having the entire record on one sheet is obvious. 

 Deliveries and credits may be compared at a glance for the benefit 

 of users who inquire as to the standing of their accounts, and in 

 addition there is little chance of any user exceeding his credit.
