The map shows the location of 565 lakes and reservoirs with a total lake area larger than 100 square kilometres or 38.6 square miles. A table shows the fifteen largest lakes ranked by their area with their maximum depth. An examination of inland hydrologic subsystems must stress the roles of...

The plate shows a graph of the maximum and minimum monthly mean flow and mean monthly river flow for 36 selected river gauging stations. Thirty-six gauging stations across Canada were selected to represent a cross section of river types and sizes. Most of the rivers are natural flow; however,...

The plate contains four maps: Annual Winds, March Winds, August Winds and Annual Maximum Wind Speed. For each of the first three maps the frequency of wind, the mean speed of wind, and the frequency of calms are shown. On all three maps the frequency scale is 1 millimetre equals 2 percent. These...

The plate contains four maps showing the mean river freeze-over date, the mean lake freeze-over date, the mean river ice-free date and the mean lake ice free date. The four maps depict, in a general way, the average dates on which freshwater bodies in Canada become completely ice-covered in the...

Contained within the 1st Edition (1906) of the Atlas of Canada is a plate that shows two maps. The first map that shows origins of the people in Maritime provinces and Eastern Quebec, circa 1901. The second map that shows origins of the people in Quebec and Ontario, circa 1901.A varying number of...

The plate contains four maps showing the Hardness of Surface Water, Total Dissolved Solids of Surface Waters, Turbidity of Surface Waters and the Chemical Quality of Typical Surface Waters of Canada. These water quality maps were based on data collected from 1970 and 1971 at national river...

The map shows the location of glaciers and ice caps and also indicates the rivers and the lakes, which are fed by a glacier (or an ice cap) meltwater. The purpose of this plate is to identify those streams which are fed by glacier meltwaters. Because of the scale of the map, many minor glaciers...

Precipitation is derived from water vapour in the air, and it includes all forms of moisture falling on the earth's surface. Condensed water vapour accumulates in clouds, and precipitation occurs when the constituent ice crystals or water droplets grow too large to resist gravitational attraction...
