 width of 22 feet on the bottom, a depth of its length, has been cut through solid 

 of 3 V 2 feet at its headgate, and a carry- rock. This conveys the water from the 



Laramie River to Blue Grass Creek, 

 which flows into the Sybille River. 

 From that stream the canals above men- 

 tioned have been constructed along the 

 higher levels of the land. Lateral and 

 sublateral ditches leading from 

 the main canals distribute the 

 water over the entire area. 



As at present completed, the 

 system of irrigation furnishes a 

 sufficient quantity of water for 

 the successful growing of crops 

 on about 60,000 acres of land. 



To reinforce and fully fortify 

 against drouth in any season, in 

 1896 water was turned into a 

 natural reservoir, which has a 

 shore line of between seven and 

 eight miles. The construction

 evaporation. It is used immediately tical impossibility. 



of a dam was completed lately 

 for another natural reservoir ad- 

 joining the L,aramie River above 

 the tunnel of the company. This 

 reservoir is now being filled with 

 water. It, with the other re- 

 sources of the company, will fur- 

 nish sufficient water to irrigate 

 120,000 acres. 



This reservoir will be among 

 the largest in the world. It is- 

 8 miles in length, averaging 2>^ 

 miles in width and about 35 feet 

 at its gieatest depth, averaging 

 1 8 feet. It will cover about 7, ooo 

 acres of land, have a shore-line of 

 about 35 miles, and will carry 

 about 120,000 acre- feet of water. 

 This reservoir will make water 

 abundant for all land under 

 ditches of the Wyoming Devel- 

 opment Company during every growing 

 month of the year. It will make the 

 destruction of crops by drouth a prac- 



after being turned into the canals. Ca- 

 nal No. 2 has no break from its head- 

 gate to its terminus, except the gates 

 along its line, which are used for the 

 distribution of water to its laterals. On 

 canals i and 3 breaks occur by reason 

 of dry streams or gulches. 



The company has other available res- 

 ervoir sites on its lands which can be 

 utilized, but they are hardly necessary, 

 considering the capacity of the reser- 

 voirs now completed.
