Khlong Bang Chueak Nang when flowing to Wat Ko temple, it splits into two courses, the upper course called Khlong Bang Noi, while the lower course called Khlong Bang Chueak Nang and formed a boundary between Taling Chan with Phasi Charoen Districts.

The khlong is called Khlong Mon from the reason that this area was the settlement of Mon ethnic people, and also called Khlong Bang Sao Thong (คลองบางเสาธง). The khlong was regarded as a strategic waterway. Therefore, a post was constructed on the khlong to be a checkpoint of the transported merchandises and passengers. The Mon peoples were appointed as the post-keepers. Throughout the 3 km (1.9 mi) length of the khlong, there are numerous old and important temples such as Wat Khrueawan, Wat Nak Klang, Wat Phraya Tham, Wat Chinorot, Wat Khrut, Wat Pho Riang, Wat Bang Sao Thong. Nowadays, the khlong is one of the famous foreign tourists' tour routes as well as Khlong Bangkok Yai or Khlong Bangkok Noi.

The cabinet had a resolution in 1967 to have Khlong Mon as a preserved khlong.
