Opening of Jinan Unsan Artificial Wetland
[Asia Economy Honam Reporting Headquarters Reporter Go Dallyeong] The Jinan Unsan Artificial Wetland, a natural-type artificial wetland equipped with settling ponds, shallow wetlands, deep wetlands, horizontal subsurface flow wetlands, and ecological ponds, has opened on a 57,000㎡ site at 1016 Unsan-ri, Jinan-eup.
According to Jinan-gun on the 3rd, the Unsan Artificial Wetland is a non-point source pollution reduction facility for Yongdam Lake, a wide-area water source for residents of Jeonbuk and Chungnam provinces. The total project cost was 9.8 billion KRW (4.9 billion KRW national funds, 3.9 billion KRW fund, 1 billion KRW county funds). Construction began in May 2018 and was completed last month.
The Unsan Artificial Wetland is expected to play a significant role in preserving the clear water of Yongdam Lake by improving the water quality of Jinan Stream, which flows into Yongdam Lake, by reducing various pollutants such as agricultural pollutants like pesticides, muddy water, and debris from roads and parking lots. These pollutants, which accumulate on the surface during normal times, are mainly washed down by rainwater during rainfall, polluting the streams.
Within the wetland area, various aquatic plants with water purification capabilities such as Jure (Scirpus), yellow iris, iris, water silver grass, cattail, fan iris, and sweet flag have been planted to help improve polluted water quality. Seasonal abundant sights will be provided with spring (phlox), summer (iris), and autumn (chrysanthemum) flowers.
Freshwater fish such as crucian carp, sand goby, snakehead, carp, and catfish, as well as various birds including mandarin ducks, little egrets, herons, great egrets, and eastern spot-billed ducks, have also been observed.

Jeon Chunsung, the governor of Jinan-gun, said, “The Unsan Artificial Wetland is located 1.2 km from Jinan-eup, so it is expected to be loved as a walking trail and resting place for residents. Also, since various species can be seen, we will continue to manage it so that it can be reborn as an ecological learning and field experience site for students.”
