Nature always has something to teach us. When we study lakes and their feed tributaries we can apply this directly to our lives.
I live in Uganda, East Africa close to one of the largest lakes in the world, Lake Victoria. This lake is a vital fresh water feed to the countries downstream. The countries include South Sudan, North Sudan and Egypt. River Nile one of the most famous rivers in the world begins its journey from this lake.
Lake Victoria is one of the African Great Lakes. With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa’s largest lake by area, the world’s largest tropical lake, and the world’s second-largest fresh water lake by surface area after Lake Superior in North America.
Lake Victoria receives 80 percent of its water from direct rainfall. Average evaporation on the lake is between 2.0 and 2.2 metres (6.6 and 7.2 ft) per year, almost double the precipitation of riparian areas.
Lake Victoria receives its water additionally from rivers, and thousands of small streams. The Kagera River is the largest river flowing into this lake, with its mouth on the lake’s western shore.
Lake Victoria is drained solely by the Nile River near Jinja, Uganda, on the lake’s northern shore. In the Kenya sector, the main influent rivers are the Sio, Nzoia, Yala, Nyando, Sondu Miriu, Mogusi, and Migori.

This Lake is a critical source of freshwater for millions of individuals in over six countries. The Lake’s water use is strictly regulated by all countries. All upstream activities in the feeder countries have a direct impact on the countries in the lower basin area.
