3.25 Newfoundland–Labrador drainage region 3.25 Newfoundland–Labrador drainage region

Profile highlights

• The landscape of the Newfoundland–Labrador drainage region is primarily composed of natural and semi-natural land area (99.6%)—built-up area, arable land and natural land for pasture together made up less than 0.5% of the total area in 2011.
• The population was 515,698 in 2011, with a population density of 1.6 persons/km².
• Surface freshwater intake from mining, drinking water plants, manufacturing and thermal-electric production was 338.1 million m³ in 2013.
• The long-term^{Note 1} average annual water yield was 324.2 km³ with a water yield per unit area of 0.85 m³/m², compared to 0.35 m³/m² at the Canada level. The average annual water yield for the Newfoundland (Island) part of the drainage region was 125.6 km³ over the period 1971 to 2013, with a water yield per unit area of 1.13 m³/m². Monthly water flows for this portion of the drainage region peak in May. Compared to other drainage regions, monthly water yield varies relatively little from year to year.
• Sources of nitrogen and phosphorus residuals in the environment include fertilizer application and livestock and poultry production. On average residual soil nitrogen on agricultural land was 56.0 kg/ha in 2011 compared to 23.2 kg/ha at the Canada level. The risk of phosphorus release from agricultural soils was high, with 6.3 mg/kg of water extractable phosphorus potentially released in 2011.
