414 HISTORY OF PASADENA. 



Water Company, taken yesterday by me, with your kind assistance, I find 

 the results to be as follows : 



MINERS INCHES. 



The total flow from Thibbets springs 56.6 



Of which there passes into the Pasadena Water Company's pipe 34.0 



Remainder flowing to the Pasadena Lake Vineyard Water Co.'s dam ....22.6 



Including 2.2 seepage : 



The flow of the Ivy springs, passing down to the P. ly. V.'s dam 10.9 



Total flow of the Flutterwheel springs 26.5 



Recapitulating, the aggregate shows as follows : 



Thibbets springs 56.6 



Ivy springs 10. g 



Flutterwheel springs 26.5 



Total 94.0 



Of which the Pasadena Water Company receives 34 miner's inches, and the 

 Pasadena L,ake Vineyard Water Company 60 miner's inches. (A miner's 

 inch equals 1-50 cubic foot per second, or 1728 cubic feet, or 13,000 gallons 

 in 24 hours.) 



As I understand the respective rights of the two companies to the 

 various springs, the Pasadena Water Company is entitled to 11-20 of the 

 Thibbets springs, and i-io of the Ivy and Flutterwheel springs. Applying 

 these proportions to the above figures of volume now flowing, the Pasadena 

 Water Company would be entitled to 34-89 miner's inches. As we have 

 seen, according to the present mode of division, this company is actually 

 receiving 34 miner's inches, which may be considered very close to the 

 mark, taking the many complications into consideration, and reflects much 

 credit upon the zanjero who arranged the device for dividing the water so 

 evenly. 



I think a tunnel properly located will develop and concentrate all the 

 water in the vicinity of the Devil's Gate, and I should be greatly deceived 

 if it did not double the volume now flowing. The advantage it would pos- 

 sess over all other methods of diversion of water would be its permanence, 

 and the fact that floods would not affect the quality nor interrupt the flow 

 of the water, which would enter the pipes free from sand, leaves, insects, 

 or any impurity.

Los Angeles, November 4, 1886. 



During 1887-88, the two companies finally agreed-upon terms of owner- 

 ship and division of the waters at Devil's Gate, and made extensive im- 

 provements, including a large union delivery pipe from the Gate down to 

 Reservoir No. i, in place of the old " Wilson ditch " which had before sup- 

 plied the Lake Vineyard side, while the Orange Grove side had an ii-inch 

 sheet iron pipe ot their own from Thibbets springs to the Orange Grove 

 reservoir. On November 9, 1888, water was first run through this union 

 pipe to Reservoir No. i. Here it was divided in proportion of 7-10 to the 

 Orange Grove Company, and 3-10 to the Lake Vineyard Company, by a 

 simple device arranged by the engineer. Col. J. E. Place. It was a brass 

 double gate perforated with 4-inch holes — seven in a row in one gate and
