Contained within the 1st Edition (1906) of the Atlas of Canada is a plate that shows two maps. The maps show the density of population per square mile for every township in Manitoba, Saskatchewan, British Columbia, Alberta, circa 1901. The statistics from the 1901 census are used, yet the...

The map shows dam sites and reservoir capacity in 1969, the water diversions in 1975, the steam-electric generating station greater than 20 megawatts operating in 1974, the industrial waste disposal well sites in 1970, the irrigated areas in 1970 and the drained and protected areas in 1970. There...

The map shows isolines for the annual precipitation and the annual evapotranspiration (in millimetres). Water is normally supplied by precipitation and lost through the processes of evapotranspiration and runoff or it may remain as surface or subsurface storage. Over long periods, generally...

The plate contains four maps of 60 minute rainfalls (in millimetres) for a 2 year return period, a 5 year return period, a 10 year return period and a 25 year return period. Each map has a detailed inset of the Vancouver area. These four maps were not analyzed for the mountainous parts of Canada...

The plate contains four maps. The first map shows the location of recording rain gauges used in the map and their number of years of record. The three other maps show the ratio 6-hour/24-hour rainfall extremes, the ratio 48-hour/24-hour rainfall extremes and the ratio 72-hour/24-hour rainfall...

Contained within the 1st Edition (1906) of the Atlas of Canada is a plate that shows 11 maps. Two maps at the top of this plate presenting isothermal lines for summer and for the entire year. The isotherms for summer display the great northern "loop" of the summer isotherm of 55 degrees...

The map represents the mean value (in millimetres) of the annual loss of water through the evaporation process from the surfaces of open water bodies, such as ponds and shallow lakes and reservoirs based on the 10-year period 1957 to 1966. The greatest mean annual lake evaporation (more than 900...

The map shows the location of the air temperature measurement stations. Fragmentary meteorological reports were prepared and published by European explorers in the North American Arctic during the late 16th and 17th centuries. Many employees of the Hudson's Bay Company kept careful observations...
