Hutoupi Reservoir, Taiwan's oldest reservoir, was built in 1846. The water surface area covers around 27 hectares. There are mountains in the background. The water banks reach a height of around 70 meters, and the waters go to a depth of around 40 meters. The reservoir was originally used for irrigation, irrigating over 500 hectares of farm land. In 1906, following an earthquake, it needed urgent repairs, which took six months. A memorial stone was erected at that time. In that same year, it became one of Taiwan's "12 Scenic Panoramas". In 1939, it became known as the Hutoupi Scenic Area. In 1954, Tainan City’s Documents Committee selected “Moonlight on Hutoupi” to be one of the “Eight Nanying Sights”. It was also known as “Little Sun Moon Lake”. Because the Hutoupi Scenic Area is south of the Tropic of Cancer, it has a tropical monsoon climate, giving it a rich animal and plant ecology. There is a golf course, strawberry garden, martyrs shrine, and a horseback riding area nearby. Your journey to the reservoir can easily include a visit to any one of these places. The beautiful scenery will make your visit worthwhile, and this is a popular place to visit on weekends.
