The demand for fresh water is highest in the southern parts of Canada due to population levels and rates of evaporation from agriculture and forestry. This map provides a national synthesis of water budget components at sub-sub-basin scale. These components currently include precipitation (rain and snow together) and evaporation on an annual basis from 1990 to 2000. The information presented is derived using computer models that aggregates point climate station data and land surface conditions observed using satellite remote sensing. As such, the water budget information is best suited for analysis using spatial and temporal trends (rather than absolute quantities at a given geographic location). Furthermore, for the first time, data from this project combined with runoff measurements from Environment Canada's HYDAT system, can be used to estimate trends in water availability across Canada.
