The detention pond is engineered to hold up to 22,000 cubic meters of rainwater during heavy storms.
The park was constructed as a response to the chronic flood risks that previously impacted the Yuanlin city center.
It utilizes a 'sponge city' concept, allowing water to infiltrate the soil rather than overwhelming the storm drain system.
The park's elevated wooden observation decks are specifically positioned to provide vantage points over the pond and local sunset views.
Construction of the park was completed in phases to integrate with the surrounding Yuanlin 184-hectare land redevelopment zone.
Yuanlin Detention Pond Natural Park is a primary flood-control infrastructure project in Changhua County that functions as a multifunctional recreational space. The site features a 2.5-hectare detention pond designed to mitigate urban flooding in Yuanlin City. The park spans approximately 7.5 hectares, incorporating walking trails, elevated boardwalks, and extensive native landscaping. It serves as a green buffer for the surrounding high-density residential zones along Yuanlin Boulevard. The design emphasizes natural drainage systems and sustainable water management techniques. Visitors can access a loop trail that encircles the perimeter of the water feature. The park is integrated with urban landscape architecture intended to support both local wildlife and public fitness activities. It is part of a larger government initiative to upgrade regional environmental infrastructure.

Bring sun protection as the park has many open, unshaded sections along the main pond perimeter.
Walk the elevated boardwalks to avoid the muddier patches of the peripheral dirt trails during the rainy season.
Visit during the late afternoon to observe local bird species congregating near the water's edge.
Do not attempt to walk into the basin or approach the water's edge during or immediately following heavy rainfall, as the site is active flood-control infrastructure.
Keep pets on leashes and clean up after them; follow signage regarding stay-off-grass areas during maintenance periods.
