The lake is also called the Holland Lake, Dutch Lake, and Hong-Mao Pei (see ang mo) because the lake was dug by the Dutch around 300 years ago during the Dutch Formosa rule by taking it source from the Bazhang River to irrigate the broad fields run by the Dutch East India Company. This system lasted until the beginning of Kingdom of Tungning in Taiwan in which the lake laid in ruins until the Qing Dynasty rule. In the late Japanese rule period, the dam was reconstructed.^[1][2]
