Footnotes:
(1) Khlong Kudi Dao was an artificial short-cut canal running north-south and dug in a loop of the Pa Sak River, which riverbed later became Khlong Hantra. The canal is defunct today, but some small stretches can still be seen parallel with Road No 3058. The canal was an extension of Khlong Ayothya.
(2) Khlong Kramang flows on the border between Hantra and Phai Ling sub-districts. It covers the stretch between Khlong Hantra and Khlong Ban Bat. Like Khlong Hantra, Khlong Dusit and Khlong Khao San, this canal was once a stretch of the Pa Sak River. The canal is named after a common fish in the Siamese waters, the Smith's Barb (ปลากระมัง).
