Profile highlights

The Northern Quebec drainage region extends across 940,193 km², virtually all of it natural and semi-natural area.
The population was 109,239 in 2011, with a population density of 0.1 persons/km².
Surface freshwater intake from mining, manufacturing, drinking water plants and thermal-electric production was 30.1 million m³ in 2013.
The long-term^{Note 1} average annual water yield was 516.3 km³—the highest in the country. The water yield per unit area was 0.55 m³/m², above the Canada level of 0.35 m³/m². Data on the monthly yield and trends over time are not available.

Notes

Footnote 1.

The water yield estimates are 42-year annual averages (1971 to 2013), with the exception of estimates for drainage region 1, which is based on 41 years of data (1971 to 2012); drainage regions 5, 7, 17 and 18 and portions of 8, 16 and 25 (Labrador), which are based on 20 years of data (1976 to 1995); and portions of drainage region 8 and 16, which are based on a 23-year average (1972 to 1994) for the Arctic Archipelago (Spence and Burke, 2008). These different time periods are used due to lower availability of hydrometric data in the North. As well, because there are fewer stations in northern Canada, only the long-term average annual water yield is publishable for these regions—data quality was insufficient to derive the monthly water yield or the change over time.
