408 JOURNAL OF FORESTRY 



2. During the latter half of July the stream from the deforested 

 area was nearly normal. In August and September, however, its 

 flow increased slightly, probably both on account of larger direct con- 

 tributions from rains, and because the loss of a storage water through 

 the transpiration from leaves was minimized. At the end of Septem- 

 ber the stream was flowing 2 per cent above its expected rate. 



3. Whether the stream flowed more or less than it would have done 

 under the influence of forest, during the fall and winter period, is 

 problematical. 



4. There was an excess of 125 per cent in the amount of measurable 

 detritus carried by the stream after the forest removal. Most of this 

 was secured during the flood quarter. 



5. Expressing the late flood and summer conditions as one quantity, 

 it may be said that the removal of the forest made available .08 inches 

 over the watershed, or .OOGT acre feet per acre of watershed, which 

 would not otherwise have been available during the period June 1 to 

 September 30. This is to be balanced against more than .05 acre feet 

 which came down as flood excess too early to be of value in irriga- 

 tion, and against the 125 per cent increase in detritus.
