Profile highlights

The Keewatin–Southern Baffin Island drainage region is a large region covering 939,569 km² to the west and north of Hudson Bay, virtually all of it natural and semi-natural area.
The density of linear infrastructure including roads, rail lines and transmission lines was the lowest in the country at 0.5 m/km² in 2011.
The population was 13,968 in 2011, with a population density 0.02 persons/km², the second lowest in the country.
Surface freshwater intake from mining and drinking water plants was 3.2 million m³ in 2013.
The long-term^{Note 1} average annual water yield was 192.0 km³. The water yield per unit area was 0.20 m³/m², compared to 0.35 m³/m² at the Canada level. Data on the monthly yield and trends over time are not available. Evapotranspiration was the second lowest in the country at 0.13 m³/m².

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.
