For most of the 20th century, the Kekaha Sugar Mill (owned by Amfac) was the centerpiece of agriculture on Kauaʻi's west side. The sugar mill had a major influence in Kekaha's development, including banking, employment, transportation, housing and utilities such as water and electricity. The mill employed several generations of local families. It closed in 2000 when the entire sugar industry in Hawaiʻi collapsed. The mill was purchased in 2005 by mainland investors who sold off its heavy machinery to other mills as far away as Africa.
Hawaiʻi's first (and only) train robbery occurred here in February 1920, when a masked gunman stopped a slow-moving sugar train and escaped with the locomotive and $11,000 taken from the labor paymaster on board. Police recovered the money in a swamp near the home of a local fisherman, whose suspicious behavior soon resulted in his arrest and conviction. The fisherman was a big fan of Western movies, and was thought to have been inspired by some of the films he had seen.
