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 lakes and lake systems. This is particularly true in Canada, where fresh water covers about 8 per cent of the surface area, an area greater than the province of Alberta, which comprises about 5 per cent of the Canadian landmass. The rate at which water is evaporated from large lake surfaces depends on the surface temperature of lakes. Although the hydraulic flow-through forces are the most significant in influencing the rate at which lakes lose water downstream on the surface, lake currents may also be established because of horizontal differences in lake water density. Wind-induced seiches have often caused substantial rapid fluctuations in lake levels, resulting in flooding and other water management problems in large lake systems. Prolonged wind "set-up" can increase lake water levels at one end of a lake causing similar problems. In the Great Lakes, for example Lake Erie, intense storms…
