The analysis of data for Harris River and Indian Creek showed that 

 their vratersheds react to precipitation in the same manner as Maybeso 

 Creek. Only minor differences exist between all three streams. 



Storm analyses 



Magnitude and frequency of floods are considered to be valuable aids 

 in evaluating the effects of changes in land use on stream regimen. 

 Serious disturbance or removal of forests may have definite effects 

 on the magnitude of flood flows. A marked increase in magnitude of 

 discharge, or frequency of flood peaks, following logging is a strong 

 indication that the changes are attributable to forest cutting; pro- 

 viding there has been no significant change in climatic factors. 



Floods \^rere catalogued for the entire period of record. A minimum 

 peak of 4.0 feet (water stage) was used as a basis for storm 

 comparison. The frequency of flood peaks, according to number and 

 periodicity, was also simimarized for all streams (table 7). 



The highest frequency of floods occurred in October on Maybeso Creek, 

 Harris River, and Indian Creek. The greatest frequency of storm peaks 

 occurred in the 4.00- to 4.99-foot class for all streams. Very few 

 flood peaks exceeded 7 feet.
