Geography and formation


After the 1997 El Niño event, Lake Kacheera lost most of its waters to Lake Victoria due to a massive water flow via Lake Kijjanebarora and its level fell by 3 metres. Lake Kachera also lost its floating island that used to be a refugium for the fish. Its shores are covered with swamps, thickets and woodlands.
Lake Kachera is a shallow lake with an average depth of 5 metres (16 feet) and also cover an area of 42 square kilometres (16 square miles) and a shoreline of 81 km. It has a maximum length of 20 kilometres (12 miles) and width of 3.5 kilometres (2.2 miles).
River Ruizi flows from the Bushenyi district and passes through Lake Kachera and Lake Kijanebalola before it enters into Lake Mburo and ending in Lake Victoria. It drains it waters into Lake Victoria via Kagera River which is its only river out flow.
River Rwizi also pours its water into Lake Victoria through Lake Kachera which is a drainage system for Lake Victoria.
