美濃平原的開發,獅子頭圳的功能扮演著重要的角色,從清代到日治時代的水利地位是如何延續並擴大,可作進一步的探討。清代由六堆美濃客家移民興設於獅子頭山下的獅子頭圳,其流路自攔水圳頭處沿著獅子頭山下到龜山間的缺口處流入美濃平原,再分注龍肚圳、中坛圳,成為二圳的共同水路,其攔水圳頭又可分水至番仔藔,清代獅子頭圳是平原上的灌溉命脈。日治時代美濃平原上同一灌溉系統三水圳,因分屬不同行政官廳管轄,先後被認定為不同的公共埤圳,造成水權的管理無法統一。明治38年(1905)整合為公共埤圳獅子頭圳組合後,繼而改修擴張為官設埤圳獅子頭圳,明治44年(1911)設置官設埤圳獅子頭圳水利組合,獅子頭圳已經從一段共同水路變成灌區廣大的水利灌溉系統。為促使日本資本家投資開發美濃平原,臺灣總督府出資改修擴張官設埤圳獅子頭圳,改變了此一原本不適合稻作的區域,從而使美濃平原的荒野地變良田。國家出資提升水利事業的公共化性質,使美濃平原上的開墾事業得以穩定發展,更成為日後臺灣稻、蔗的重要產區,其產業的發展實與水利事業的開發有極其密切的關係。
The development of the Meinong Plain and the functions of Shihzihtou Irrigation System played an important role. How the status of irrigation System continued and expanded from the Qing Dynasty to the Japanese colonial era can be further discussed. During the Japanese Occupation era, some irrigation systems on the Meinong Plain were gradually recognized as public irrigation systems, then reorganized into the Public Irrigation System Association, and expanded into the Official Irrigation System Association. After that, it becomes the Public Irrigation System Association, and finally became the Irrigation Association. In order to develop the Meinong Plain, the Government of Governor-general of Taiwan invested in the renovation and expansion of Shihzihtou Irrigation System, an Official Irrigation System, changing this area that was originally unsuitable for rice farming, thus turning the wasterland of the Meinong Plain into fertile farmland. The state funded the public nature of the irrigation System project, allowing the reclamation business on the Meinong Plain to develop steadily, and it became an important rice and sugarcane production area in Taiwan in the future. The development of its industry is closely related to the development of the irrigation System project.
