The map shows the mean daily temperatures based on the 30-year period 1941-1970 for the warmest month in Canada. Although, the most direct and the most intense incoming solar radiation occurs in June, there is a lag in the warming of the Earth’s surface. As a result the warmest month in Canada is...

The map shows the annual snowfall (in centimetres) based on the 30-year period 1941-1970. Snowfall is measured by inserting a ruler into the new snow at several points to obtain its depth and to estimate the degree of drifting or scouring that has occurred. The water equivalent of snowfall for...

The map shows the location of the six hydrogeological regions in Canada and the location of observation wells. The terrain composition is also shown on the map, which includes crystalline rocks, mixed crystalline rocks, folded sedimentary rocks and flat lying sedimentary rocks. The southern limit...

The map shows the location and the number of years of recorded data for the Water Survey of Canada streamflow gauging stations and the Quebec Department of Natural Resources stations. Almost 9 per cent of all the world's river water which flows to the oceans has its source within Canada's...
