The landscape of the Winnipeg drainage region, which extends from Lake Winnipeg towards Lake Superior and includes the cities of Kenora and Dryden, was dominated by natural and semi-natural areas (98.1%) in 2011. Built-up, arable land and natural land for pasture accounted for less than 2% of this drainage region.
The population was 82,775 in 2011, with a population density of 1.0 persons/km2.
Surface freshwater intake from manufacturing, thermal-electric production, drinking water plants and mining was 131.8 million m3 in 2013.
The average annual water yield was 25.9 km3 over the period 1971 to 2013. The water yield per unit area was 0.24 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 0.40 m3/m2, compared to 0.23 m3/m2 at the Canada level.
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 31.6 kg/ha in 2011 compared to 23.2 kg/ha at the Canada level.
