1.
Area includes the Canadian portion of the Great Lakes.
2.
Water area figures are calculated from the Canada-wide 1 km water fraction derived from National Topographic Database maps.
3.
Basins at the US-Canada border exclude inflow from U.S. portion of basin region.
4.
Precipitation has been estimated from an Inverse Distance Weighted interpolation of the 1971 to 2000 normals.
5.
The generating capacity refers to the maximum power capability from hydro plants. The survey coverage for those plants is limited to those utilities and companies that have at least one plant with a total generating capacity of over 500 kilowatts.
Note(s):
These drainage regions and associated flow measures are adapted from Pearse (1985) (see full reference below). Some of these river basin aggregates have more than one outflow.
