a just estimate of the various values can be made. It may he more ecouom- 

 ieal In this case to remove the dam, in order to secure land for farming; 

 but the evidence at pre'^ent indicates that the dam should be raised rather 

 than lowered. 



COXCLUSION. 



Fruni the data inrsciitt'tl, it is evident that tlie stiirafie capacity of lakes 

 can be increased by dannning, and that by properly mani])nlating these 

 dams the excess accumulated can be discharged during periods of minimum 

 rainfall. This will benetit the streams to which the lakes aro tributary 



(1) by decreasing the maximum discharge, thus preventing floods, and 



(2) by increasing the minimum discharge, which will add to all the ele- 

 ments that have been enumerated in stream valuation. 



By analyzing the conditions carefully in each lake these changes can 

 be made so that the value of the lakes and the property adjoining, when 

 considered as a whole, will be increased. 



Many details are yet to be worked out. Imt the advisaliility of this pro- 

 cedure is already apparent.
