The union of lakes - the union of lands - the union of states none can sever - the union of hearts - the union of hands - and the flag of our union for ever!
A lot of lakes today are artificially made to generate hydro-electric power, for domestic water supply, for industrial or agricultural use, or for aesthetic and recreational purposes.
There are more than 1500 lakes in Switzerland containing around 6% of Europe's fresh water stocks. The largest of these lakes are Lake Geneva, Lake Constance and Lake Maggiore.
Lakes differ to lagoons and estuaries due to the fact they are not connected to the ocean. A lake is also larger and deeper than other inland water bodies such as ponds.
Water in most lakes flows in and out via rivers and streams. Lakes that only lose water by evaporation or underground seepage are called endorheic lakes.
