a just estimate of the various valius can be made. It may he more econom- 

 ical in this case to remove tlie dam, in order to secure laud for farming; 

 but the evidence at present indicates that the dam should be raised rather 

 than lowei'cd. 



CONCLrSION. 



From the data presented, it is evident that the storaiie capacity of lalces 

 can be increased by damming, and that by properly niani]mlating these 

 (lams the excess accumulated can be discharged during periods of minimum 

 rainfall. This will benetit tlie streams to which the lakes are 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 enunierated in streajn valuation. 



By analyzing the conditions carefully in each lake these changes can 

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

 considered as a whole, will be increased. 



Many details are yet to be worked out, but the advisability of this pro- 

 cedure is already a])])arent.
