Effects of forests on the water supply. 



They tend to increase the water supply. 



But little in this county ; amount of rain-fall or 

 precipitation determined by the condensation 

 as caused by the mountain ranges. 



Forests prevent the snows from melting too rap- 

 idly in the spring and protect the springs and 

 rivulets. 



They keep the ground moist and promote rain- 

 fall. 



The headwaters of all important streams are 

 protected and nourished by forests. 



Forests prevent the snows from melting early in 

 the spring and keep the streams alive. 



All streams are, in a measure, dependent on the 

 forests.
