Hydrometric monitoring in northern Canada, as in much of the country, was reduced during the mid-1990s in response to fiscal pressures on the federal government. This study uses a combination of canonical correlation and multiple regression analysis to quantify the influence of discontinuing these gauges on prediction of ungauged streamflows in the region. Thirty-four stations in the Mackenzie Basin measuring streamflow from catchments in the Yukon, the Northwest Territories, northern Alberta and northern British Columbia were selected for the analysis. Twelve of the 34 stations are now closed. The difference in the predictive capability, as determined by a jack-knife procedure, between using only the active stations versus using both [...]
