the ditch. Owing to its position this reservoir does away with the 
usual operation troubles at the lower end of long canals. The re- 
maining reservoirs of the system are supplied by the Larimer County 
Canal, and the water stored in them may be used only by exchange. 
These reservoirs are listed below, with their capacities :

The water rights of the company in the Cache la Pouclre are listed 
on pages 14 and 16. The company also has decrees for appro- 
priations made in other districts, but these are not listed. The 
owners of rights in the Smith Ditch, with a single exception, ex- 
changed their rights for stock in the company. With this exception 
the appropriations of the company are owned joint!} 7 . 
The system of water delivery on the Larimer County Canal is 
comparatively simple so far as the user is concerned. At any time 
there is water in the canal for direct irrigation he is entitled to his 
pro rata share and may obtain it by notifying the ditch rider that 
he wishes it turned out. The water delivered is measured over 
rectangular weirs, and the riders carry tables from which the proper 
depth over the weir may be taken directly. These tables are based 
on the delivery of 1.677 second-feet, or 40 " farmer's inches," to the 
share. At this rate the 600 shares of the company require 406 second- 
feet, and this demand is supplied by a flow of 485 second- feet in the 
canal. Incidentally this indicates a loss of approximately 16 per 
cent in the canal. However, the canal carries a full supply only a 
short time during the season, and deliveries are usually made at the 
rate of 20 or 30 " farmer's inches " to the share. To determine the 
depth over the weir for the delivery of less than 40 inches to the 
share, the number of inches is multiplied by the number of shares 
to be satisfied and the result is divided by 40. The quotient is the 
equivalent number of shares on a basis of 40 inches to the share, 
and the corresponding depth is taken directly from the table. 
The amount of water to be carried in the canal at various times 
is determined by the superintendent and the board of directors and 
depends on the supply in sight and the disposal of it necessan- to 
finish the season in good shape. At the high stage of the river 
plenty of water is usually received from the mountain ditches, on 
exchange and on direct appropriations, but as the supply diminishes 
enough water is held up to insure proper irrigation of late crops, such
