cubic feet, the amount considered necessary for canal purposes 

 alone. Such a dam, Mr Bogart estimates, could be erected for 

 about $1,000,000. 



The work performed under the direction of the writer in 1893 

 was of an entirely different character. The report of 1890 having 

 indicated the Mount Morris canyon as a desirable location, with 

 a number of sites pointed out, of which general investigations 

 had been made, it became desirable to investigate those sites in 

 detail and to prepare close estimates of the cost of constructing 

 dams at each. Detailed investigations were accordingly made 

 of the three sites favorably reported upon in 1890, the results of

which may be found in the Annual Keports of the State Engineer 

 and Surveyor for 1893 and 1894, where estimates of the cost of 

 the several dams are also given in detail. Referring to the esti- 

 mates, it appears that at site No. 1, in Mount Morris canyon, a 

 dam raising the water surface 130 feet would cost, if built of 

 concrete alone, $2,450,000, but if built with sandstone faces 

 throughout, except for the spillway, where granite is provided, 

 the estimated cost would become $2,590,000. A dam of the same 

 hight at site No. 2, if built throughout of concrete, would cost 

 $2,000,000, but with sandstone faces and independent spillway the 

 cost would be $2,720,500. 



In regard to the total storage to be obtained in Mount Morris 

 canyon the following are the figures :t( sites Nos. 1 and 2, the two 

 sites chiefly considered : At site No. 1 a dam of 130 feet in hight
