The reservoir has a total water storage capacity of approximately 1.5 million tons.
The facility was strictly off-limits to the public for nearly eight decades until its partial opening in 2011.
The forest contains rare, mature cedar trees that were planted at the time of the reservoir's completion in the 1930s.
The dam embankment is made of stone blocks rather than modern concrete, reflecting early 20th-century civil engineering methods.
The site acts as a key water source for the nearby Yangsan and Busan metropolitan areas.
Beopgi Reservoir is a restricted water supply facility featuring a dense, century-old forest of cedar, cypress, and Japanese larch trees. Established in 1932 during the Japanese colonial period, the area was closed to the public for 79 years to protect the water source. Visitors walk along a guided path that transitions from a flat forest floor to a stone staircase leading to the top of the embankment. The site houses a massive dam wall constructed with stones transported from the local area. From the embankment, visitors can view the reservoir's calm water and the surrounding mountain ridges. The forest is characterized by towering trees planted in orderly rows, creating deep natural shade. Drinking water, food, and pets are strictly prohibited within the park boundaries to maintain water quality. The area serves as a rare example of a well-preserved, semi-wilderness ecosystem in the Yangsan region.
