with the highest stream stages. Water temperature of shallow streams 
appears to respond more rapidly than deeper streams to seasonal air 
temperatures and other modifying influences such as snowmelt and pre- 
cipitation. For example: mean monthly water temperature of Indian 
Creek, the shallowest of the study streams, was several degrees colder 
during winter months and generally warmed more quickly during the 
summer months than did the other streams (fig. 13).
