Irrigation ditch
An irrigation ditch was a man-made body of water that supplied water to crops.

In 2376, The Doctor, in the guise of Father Mulligan, told a story to the people of Fair Haven about two farmers, one of whom broke the other one's plow and refused to replace it. The plow's owner retaliated by clogging his foe's irrigation ditch. ()
