Water yield of geographic area, volume

Water yield refers to the amount of freshwater derived from unregulated flow measurements for a given geographic area over a defined period of time and is an estimate of the renewable water. Water yield also includes a volume of water that is not renewable, specifically that portion of glacial melt water coming from receding glaciers.

Geographic area refers to areas whose boundaries are specifically delimited in accordance with well-defined concepts and which, in total, cover the entire landmass of Canada. It excludes Canadian territorial enclaves abroad.

The data for this variable are reported using the following measurements:

  • Cubic kilometres per month
  • Cubic kilometres per year
