Man-Made Changes in the Freshwater Input Rates of Hudson and James Bays. Prinsenberg, S. J. Canadian Journal of Fisheries and Aquatic Sciences, 37(7):1101–1110, July, 1980.
Paper doi abstract bibtex PRINSENBERSG. J,. 1980. Man-made changes in the freshwater input rates of Hudson and James bays. Can. J. Fish. Aquat. Sci. 37: 1101-1110. The freshwater input rates of the Hudson/James Bay region were obtained on a monthly time scale and include contributions of evaporation, precipitation. and river runoff. The yearly mean precipitation minus evaporation rate shows that it behaves as an oceanic region supplying the ovcrlying air mass with moisture. The monthly runoff rates for the total region and James Bay alone h a ~ ~meinimum values during the wintcr and maximum values during the spring freshet. The total freshwater input can be divided into a winter and summer season. The large input of the summer represents an average monthly acidition of a 10.0-cm layer of fresh water while the smaller winter input amounts to addition of a 0.5-cm layer of freshwater. Annually, the total surface area receives a layer of 64 cm of freshwater. During the 1980s, four hydroelectric developments will cause temporal changes in the freshwater input cycle as winter river ruiloff rates will increase to values comparable to spring peak runoffs. In the Nelson-Churchill River development, the Churchill River runoff will be reduced to 2%; of its natural state during the winter and to 54y; during the summer. This water will increase the runotT into the Nelson River Delta by 52':; in the winter and 1OL,\textlessin the summer. Similarly, the Eastmain River runoff will be reduced by 79(//;. The La Grande River will double ~ tysearly averaged runoff rate and experience a 50054 increase in runoff during the winter. The other two developments, Nottaway-Broadback-Rupert rivers (N.B.R.) and Great Whale-Little Whale proposals, will experience similar changes: large increases in the winter runoff rates and small decreases in summer rates. The total freshwater input into Jamcs Bay will be doubled during the winter months. In addition, half the future input will occur in the northern region which now receives only 20i,;. The La Grande River winter runoff rate will equal in magnitude that of the Nelson River Delta which presently accounts for 25C/; of the Hudson/James Bay winter runoff. The runofT for the total HudsonjJames Bay region will also experience the largest changes during the winter when the average monthly runoff rate will increase by 52:4, due largely to the La Grande Complex. On the other hand, the summer runoff rate for the total region will decrease by 6(/:,.
