| Abstract | (unpublished)
The map shows the annual runoff in millimetres. Annual runoff varies from year to year owing to variations in precipitation, evaporation, and natural storage. The map presents
the long-term average of these annual variations. The annual runoff is smallest in southern Saskatchewan and southeastern Alberta with values lower than 25 millimetres. The greatest annual runoff occurs on the west coast of British Columbia where
values reach over 3200 millimetres. In the east of the country, the values are around 1000 to 1400 millimetres on the coast of Newfoundland and decrease as one goes west to reach values lower than 200 millimetres in Manitoba. The map has been
compiled using actual and synthesized data from a number of sources. In most parts of the country, isolines of mean annual runoff are shown at 100-millimetre intervals, but for mountainous terrain, particularly in British Columbia, such an interval
is not possible on a map of this scale. A few representatives isolines are shown, to indicate the t |
