Discharge records published by such agencies as the Water Resources Branch of the Department of Northern Affairs are usually in the form of average daily discharges. Such records are of little value for studying the peak instantaneous flows, particularly on small watersheds. The obvious method of obtaining the peak instantaneous flows on a watershed is by review of the recorded stage hydrographs. Generally, however, these records are not readily available. Further, the task of analysis is extremely time consuming if a long period of record is involved. An alternative method to the above which is much more expedient, is to utilize the average daily discharges by applying a conversion factor to these flows to derive the peak instantaneous discharges.
