Some channels were less than 60 feet [20 m] long, but others extended nearly a mile [more than a kilometer] and powered several mills stationed along the channel.
Daži kanāli bija tikai 20 metrus gari, citi stiepās vairāk nekā kilometra garumā un apgādāja ar ūdeni vairākas kanālu krastos uzbūvētas dzirnavas.
