The accompanying diagrams (Figs. 15-17) represent graphically 

 the variations in discharge during 1897-1899 which are given in 

 detail in the foregoing tables. From these figures it is readily seen 

 that the average flow of the Octoraro past Kowlandsville is rarely 

 more than 500 cubic feet per second, except during December or the 

 first months of the year when the melting of the snow and the 

 spring rains swell the stream to nearly twice that discharge. The 

 diagrams also show that the rises in the water are rapid and that 

 the fall in the water occurs within the next succeeding day or two 

 unless there are long continued rains.
