Jeonpyeongje Reservoir was built in 1943 to supply water for agricultural purposes to farms in the Maewol-dong and Byeokjin-dong regions as well as to prevent both floods and droughts. Starting in 1999, the reservoir was changed to a rest area, with a wooden deck crossing the reservoir to the man-made island in the middle. The area now serves as a waterside relaxation and eco-exploration space for family visitors.
