THE IRRIGATION AGE.

uted by five large and several small canal companies, 

 one of the largest being owned by the city of Salt Lake, 

 this canal being about thirty miles long and supplying 

 water for irrigation purposes in that city as well as to 

 the original owners of the waters of Parley's Canyon, the 

 waters of which have passed, by exchange, from the 

 farmers to the city. 



The several canal companies have, by right of

agreement with the owners of land adjacent to Utah 

 lake, the privilege of raising the waters of the lake to 

 3' 3^", compromise level, at which point the discharge 

 into the Jordan is about 500 feet per minute, and when 

 3' below compromise point the flow is about 90 per 

 second. At the present time (October, 1902) the lake 

 is lower than at any time in its known history, as a re- 

 sult of which the discharge is less than 75' per second. 

 This condition is caused by deficiency in precipitation

during the past winter, as a result of which none of 

 the canals are able to supply the demands made upon 

 them. Foreseeing this, in July of the present year, 

 and to save several thousand acres of standing grain, 

 three of the canal companies voted to install a pumping 

 plant at the outlet of Utah lake for the purpose of lift- 

 ing the waters of the lake into the Jordan river and 

 thence into the canals. 



This undertaking was placed in charge of F. C. 



Kelsey, late city engineer of Salt Lake City. Surveys 

 and plans were made and the contracts for the installa- 

 tion of machinery and the building of foundations were 

 given to Gardner & Ingalls, of Lehi, Utah. Buildings 

 to be built by the canal companies. 



The plant, when completed, will contain four 40" 

 double suction special low running centrifugal pumps, 

 feed with "Y P" suction of 40" diameter, with a dis- 

 charge pipe of 48", giving a capacity of 100 cubic feet 

 per second of time for each pump under a 5.5' head. 

 Each pump will be separately driven by a 100 H. P. 

 Westinghouse Type "C" induction motor, running at a 

 speed of 580 revolutions, electric power being furnished 

 at potential of 16,500 volts to the motors through step- 

 down transformers at 440 volts. 



The entire plant, when complete, will have a capac- 

 ity of 400 second feet of water per second; and the 

 guaranteed efficiency of this completed plant from the 

 low tension' side of the transformers when lifting 400 

 second feet of water 5' will be 40 per cent. 



What is known as the two upper canals divert 

 waters from the Jordan at a point about eight miles

below its outlet from Utah lake; two of the others have 

 their intake 52' below what is known as the upper 

 canals. From this point two miles below is located the 

 Salt Lake Cit'y Water & Electric Co., one of the larg- 

 est power plants in the State, furnishing power for 

 the power plant; tile canal companies controlling the 

 pumping plant agreed to furnish to the electric power 

 company, for generating power to operate their plant, 

 one-third of the amount of the water in excess of the 

 natural flow of the river, this water, upon passing 

 through the power plant, part of it discharging into 

 two of the canals 52' below, the balance into the river 

 72' below. The power company enlarged the Utah & 

 Salt Lake canal from its head to the plant to a suffi- 

 cient size to carry the water used by the power plant in 

 addition to the regular supply carried by the canal. 



The practical success of the pumps is not doubted, 

 and barring the institution of injunction suits, as has 

 been threatened by the owners of land bordering on 

 shallow Utah lake, the beneficial effect of producing a 

 largely increased flow of water the river for the 

 canals ought to be immediate within a few hours from 

 starting to raise the lake waters over the outlet bars. 

 It is feared by the lowering of the lake level to an
