Springs named after Kanaloa
Just south of the ridge separating Ka`alaea from Waiahole is a small hill facing the sea, named Pu`u Kahea (Hill-of-Calling), where Hi`iaka, the sister of Pele, is said to have chanted. Below the hill is a spring and pool named Hi`iaka. This spring watered the fine group of lo`i which in 1935 was still owned and cultivated by Mrs. Ka`ao`aoloa Kukahiko, who lived with her family on Pu`u Kahea, from ancient times the home-site of her forebears. The flats to seaward were also irrigated with water from this spring. Above Hi`iaka pool were other lo'i. There were a few small lo`i watered by springs between Pu`u Kahea and the sea.
Farther up the main valley on the north side is a spring named for the god Kanaloa (to whom, with Kane, is attributed the opening of many springs throughout these islands); and near this spring is another named Ka-houpo-o-Kane (The Diaphragm-of-Kane). These springs were the sources of water that used to irrigate lo`i north of the main stream below the ridge toward Waiahole. Below this, also north of the stream, was another lo`i section irrigated from a spring named Keahue.
There were extensive irrigated flats along the main stream, Ka`alaea, from the low hills to the seashore, a distance roughly of a mile and a half.
