Daemyeong Reservoir, located adjacent to Dalseong Marsh, is at the convergence point of the Nakdonggang River, Geumhogang River, Daemyeongcheon Stream, and Jincheon Stream. This area is a rich ecological reserve, home to a diverse range of wildlife including the narrow-mouthed toad, leopard cat, weasel, common kestrel, and water deer, along with various wild plants. Visitors to the area can explore narrow-mouthed toad habitats, observation decks, ecological exploration trails, and photo zones. There's also a narrow-mouthed toad ecological learning center for educational experiences. The surrounding landscape, with its stretches of silver grass and reeds along the walking decks, offers a picturesque setting, particularly attractive for autumn photography.
