"Kids used to 'flume the ditch' with air mattresses, boogie boards, inner tubes -- anything that could float. They rode down different sections of it whenever they could.” The ditch" is the Kohala Ditch, the irrigation system that sugar plantations in the area used to direct water from the lush valleys to the arid plains where their crops were planted. Stretching 22.5 miles, the system included 57 tunnels, 19 flumes and six miles of open ditches.
Currently Not in Operation. The Kohala Ditch Project Working Committee is projecting an October 2008 completion.
