. Eventually, the Nile valley bed silted up high enough to let the flooding Nile overflow into the Faiyum hollow, making a lake in it. The lake is first recorded from about 3000 BC, around the time of Menes (

); however, for the most part it would only be filled with high flood waters. The lake was bordered by neolithic settlements, and the town of Shedet grew up on the south where the higher ground created a ridge. In 2300 BC, the waterway from the Nile to the natural lake was widened and deepened to make a canal that now is known as the Bahr Yussef. This project was started by

. This canal fed into the lake. This was meant to serve three purposes: control the flooding of the Nile, regulate the water level of the Nile during dry seasons, and serve the surrounding area with irrigation. There is evidence of ancient Egyptian pharaohs of the twelfth dynasty using the natural lake of Faiyum as a reservoir to store surpluses of water for use during the dry periods. At the lake there are the remainders of the oldest known paved road in the world, the

'' as situated below the labyrinth of the first gods of Egypt, and opposite the city of Crocodiles (modern city of Fayyum). The immense waterworks undertaken by the ancient Egyptian pharaohs of the twelfth dynasty to transform the lake into a huge water reservoir gave the impression that the lake was an artificial excavation, as reported by geographers and travellers during classical times. The lake was eventually abandoned due to the nearest branch of the Nile shrinking from 230 BC.

Etymology

The name ''Moeris'' is a Greek version (reformed as if from Greek Μοῖραι " the Fates") from Egyptian ''mer-wer'' 'great canal'. Amenemhat III, who started this project, was also known as Moeris. In ancient Egypt, the lake was also variously called 'the lake', 'pure lake', and 'Osiris' lake'. During the Middle Kingdom, the whole area around the lake was often referred to as ''mer-wer'' as well. Similarly, the Late Egyptian word '' Piom'' 'sea', originally restricted to Lake Moeris, came to be used to refer to the city of Crocodilopolis (modern Faiyum), then to the entire region in later times.
