The lake depth is maintained at a consistent 3 meters throughout the reservoir.
The park layout is inspired by the form of a dewdrop, symbolizing the birth of a new city.
It hosts an annual festival featuring a high-tech musical fountain show with choreographed water jets and lights.
The park functions as a major habitat for migratory birds due to its constructed wetland zones.
Construction of the park was part of a larger plan to create a 'green corridor' through the center of Sejong City.
Sejong Lake Park is the largest man-made lake park in South Korea, spanning approximately 61 hectares. It features a central lake covering 322,800 square meters that serves as the heart of the Sejong administrative city. The park is divided into five themed islands, including the Floating Island, Eco-wetland Island, and Leisure Island. A 4.7-kilometer walking path and a 4.2-kilometer bicycle path encircle the water. The site includes a musical fountain system, a sandy beach area, and a large stage for cultural performances. It utilizes water diverted from the Geum River to maintain the lake's ecosystem. The park serves as a green buffer zone within the planned capital region, connecting directly to the nearby National Library of Korea. Various pavilions and observation decks are positioned around the perimeter to offer views of the surrounding Sejong urban landscape.
