“Kaulana ‘o Nā Wai ‘Ehā” “Famous are the Four Great Waters of Waikapū, Wailuku, Waiehu, and Waiheʻe.”
This well-known saying attests to the traditional, historical, and cultural significance of the four ahupuaʻa within the moku of Wailuku and their fresh water resources. Nā Wai ‘Ehā, was once the largest contiguously cultivated loʻi kalo growing region in all of Hawaiʻi. It also served as the primary ritual, political, and population center of Maui. The vast water resources of Mauna Kahālāwai (West Maui Mountains) supplied these four streams with the life giving waters of Kāne. This allowed the Hawaiian population of this area to develop expansive irrigation and agricultural systems unique to Hawaiʻi. The rich history of Nā Wai ‘Ehā, is directly linked to the abundance of wai. Hawaiians thrived for many generations in this region by cultivating loʻi kalo (wetland kalo), fishing in natural and manmade inland fishponds, gathering native stream life such as ʻoʻopu, hīhīwai, and ‘ōpae, and collecting drinking water from springs.
