Location

Tapjeong Reservoir (Korean: 탑정 저수지; also Korean: 탑정호; RR: Tapjeongho) is a reservoir that has been classified as the second great scenic location in Nonsan, South Korea by the municipality. It is located in Mujeok-myeon, Gayagok-myeon, and Yangchon-myeon in Nonsan, outside of the city proper. Freshwater fish such as carp, mandarin, and catfish are in the body of water.^[1] Other significant fauna include cockscomb pearl mussels and golden and red-bellied frogs.^[2] The water is used in part for irrigation of down-stream farms. The dam was recently re-built. There are a number of hotels and restaurants along the circumferential road where it is near the dam. Swimming is prohibited, though fishing is permitted and boating, including water-skiing, on the lake.

The reservoir was constructed from 1941 to 1944.

During the second decade of the twenty-first century, work was completed on the waterfront, including an "eco-park" with walkways over a part of the reservoir and introduced aquatic and terrestrial plants.^[3]

During the drought of 2012, the lowered water level in the reservoir killed more than two thousand of the rare large mussels.^[2]
