Since the early sixties, considerable effort has been made to collect information on the hydrological regimes of the rivers of northern Quebec. It is during that period that most of the gauging stations were put into operation and therefore, after 15 years of record, we have in hand enough data to get a better understanding of the different conditions prevailing on these rivers.This part of Quebec is characterized by flat ground and low precipitation and so we could expect a light runoff. On the other hand, the great number of lakes and marshes of the region contributes to the lamination of floods and the increase of the low flows.The hydrological study concerns mean flows, water balance, seasonal variations, low flows, and floods. To realize these studies, we have chosen more than 30 stations located in the regions of James Bay, Hudson Bay, and Ungava. The record period varies from 12 to 15 years (1960–1975).
