Figure 14. Trends in stage of water-surface elevation at the U.S. Geological Survey streamflow-gaging station 14200000, Molalla River near Canby, Oregon. (Stage was determined for the 5-year recurrence-interval peak [570 m³/s, or 20,100 ft³/s], the 5 percent exceedance value [110 m³/s, or 3,800 ft³/s], the median discharge [19 m³/s, or 670 ft³/s], and the 95 percent exceedance value [1.7 m³/s, or 60 ft³/s]. Gaging station moves and datum shifts are shown on the graph as is the peak of record on December 22, 1964.)
