Annual water yield for selected ecoprovinces

Annual estimates of renewable freshwater for selected ecoprovinces from 1971 to 2014. Water yield is an estimate of freshwater runoff into streams and rivers and provides information on renewable freshwater supply. An ecoprovince is a subdivision of an ecozone characterized by major assemblages of structural or surface forms, faunal realms, vegetation, hydrology, soil and macro climate. Ecoprovinces and ecozones are part of the Ecological Land Classification (ELC) which is a hierarchical framework used by Statistics Canada.
