There is a water battle brewing on the Westside of Kauai, and it’s time for the public to take notice.
The Waimea River system is one of the most expansive natural water systems in the Pacific. The system is made up of dozens of streams and tributaries encompassing 85.9 square miles with a peak elevation of 5,243 feet.
In total, it contains 38 streams amounting to 276.4 miles in length. This natural wonder is truly a sight to behold and is a precious resource.
It is well documented that Native Hawaiians maximized the life-giving resources of the Waimea River system. At the time of Western contact, records show that terraced loi kalo (taro patches) extended 8-10 miles inland and expanses of wetland kalo cultivation could be found deep into Waimea Canyon. Captain Cook noted upon his return to Waimea in 1784 that West Kauai “inhabitants” far surpassed “all the neighbouring islanders in the management of their plantations.”
This kalo complex was fed by an intricate ditch system. The famous Kikiaola ‘auwai system traversed the canyon and was an engineering masterpiece created by the early Hawaiians to reroute stream waters to neighboring loi before returning the water back on its natural course. This allowed for cultivation of every usable foot of land for kalo production. Simply put, Hawaiians maximized the resources of the canyon to create a community that flourished without significantly altering or exploiting those resources.
Fast forward to 2016. Remnants of the famous Kikiaola ‘auwai system can still be found, but the Waimea River system is barely recognizable. In the early 1900s, sugar planters supplanted the Hawaiian irrigation systems with their own ditch system. They built the Kokee and Kekaha ditches that did much more than redirect the stream waters. These ditches diverted most of the water at their highest points, turning the once roaring streams into trickles. As a result, the expansive loi kalo complex dwindled and the environment suffered. The trade-off at the time was jobs — sugar provided a steady economy for the Westside of Kauai.
In 2001, the last of the sugar companies left West Kauai. Logically, the water would be returned to the streams, right? Not so fast. Upon their departure, the sugar companies handed the Kokee and Kekaha ditch systems to the State of Hawaii. The State of Hawaii then handed over control of the ditch to the state-run Agricultural Development Corporation (ADC) who in turn, has entered into an agreement with the Kauai Agricultural Association (KAA), an organization of primarily seed companies who operate in West Kauai, to manage the ditches.
Current agricultural tenants under the ADC cultivate a mere fraction of what once was occupied by sugar and the crops are far less thirsty. However, ditch water has not been returned to the streams. And millions of gallons are wasted via drainage canals created specifically to release excess water directly to the ocean, resulting in heavy silt runoff.
For decades, kalo farmers have been calling for stream flows to be restored to their pre-sugar levels. Their calls have been ignored thus far. However, Poai Wai Ola, a hui of Waimea and Makaweli kalo farmers, have sought relief from the Commission on Water Resource Management to restore stream flow levels. The parties will be engaging in mediation soon. This is an issue we will follow closely and continue to provide updates on. It is time for the ADC and KAA to “come correct,” end the mismanagement and waste of this public trust resource and restore the flow!
