If John Speke could see lake Victoria today, painting what he saw would have caused him most likely shock and disbelief. The lake has become a smelly, suffocating from algae, a large body of water.
Ecological health of lake Victoria has been deeply undermined by the rapidly growing population, boom in fish exports, the disappearance of some fish species, the rapid growth of algae and the discharge of untreated sewage by industrial enterprises. Most of the damage is extensive and irreversible. The traditional way of life of the lake communities almost destroyed. Scientists are concerned that soon the lake Victoria may become dead.

The total area of lakes on earth — about 2.7 million km 3. that is 1.8 % of the land surface.
The main characteristics of the lake:
the area of the lake – water surface area;
length of coastline – length of the water’s edge;
the length of the lake – the shortest distance between the two furthest apart points of the coastline, the average width — the ratio of area to length;
lake volume – the volume of the basin filled with water;
average depth – the ratio of water mass to the area;
maximum depth is a direct measurement.
The biggest area of water surface of a lake on Earth — Caspian (376 thousand km2 when water level is 28 m) and the deepest-Baikal (1620 m).
Characteristics of the largest lakes in the world are given in table. 1.
In every lake there are three interrelated components: basin, water mass, vegetation and fauna of the reservoir.
