1. Crater lakes
- Earth movements leads to outpouring of lava to form a volcanic cone
- Magma in the vent cools and solidifies on top of a volcano
- The top of the volcano may be blown up by a violent eruption or magma in the vent cools and contracts, to leave behind a depression called a crater.
- Rainwater or ground water may fill the depression to a form a crater lake
- Such lakes are small in size, generally salty and lack outlets.
Examples
- Lake Paradise (on Mt. Marsabit)
- Central Island crater lake (Turkana)
- Lake Chala (Kenya - Tanzania border)
- Lake Sonachi (S.W - lake Naivasha)
- Lake Muharua (Uganda)

2. Kettle lakes
- Ice blocks within the till melts.
- This leaves behind a cicular depression
- Melt water fills the depression to form a lake
- Such lakes are common in glaciated lowlands
Examples
- Lake Mahoma
