The reservoir was renamed in 1922 to honor Robert Peirce, a former Municipal Engineer of Singapore who oversaw significant waterworks projects.
The water within the reservoir supports a complex ecosystem that includes rare freshwater fish species native to Singapore.
The forest surrounding the reservoir contains native species such as the Jelutong, Terentang, and various wild gingers.
It is a significant site for birdwatchers, frequently visited by species like the White-bellied Sea Eagle and Oriental Pied Hornbill.
The park serves as a critical buffer zone, helping to prevent sedimentation and pollution from entering the water supply.
Parts of the area were used as filming locations for local television period dramas due to the well-preserved forest aesthetics.
Lower Peirce Reservoir Park is one of the oldest reservoirs in Singapore, dating back to its completion in 1912 as the Kallang River Reservoir. It serves as a vital catchment area for the island's water supply and is framed by mature secondary rainforest. The park features a raised boardwalk that meanders through the forest floor, allowing visitors to observe flora and fauna without encroaching on the habitat. The area is part of the Central Catchment Nature Reserve, providing a sanctuary for long-tailed macaques and diverse bird species. Visitors can access a panoramic vantage point that overlooks the reservoir waters. The surrounding ecosystem includes trees that are over 100 years old, representing some of the last remaining primary and secondary forest remnants in the region. Unlike more manicured city parks, this site maintains a rugged, natural character with uneven terrain in non-boardwalk sections. It remains a key location for environmental research and nature appreciation.

Bring insect repellent as the dense vegetation attracts mosquitoes.
Wear comfortable, covered walking shoes as some sections involve natural forest trails rather than paved paths.
Keep all food items secured inside bags to prevent long-tailed macaques from approaching you.
Do not attempt to swim in the reservoir or fish in the water, as these activities are strictly prohibited to protect water quality.
Do not feed the wildlife, stay on marked trails to protect the forest floor, and refrain from littering to preserve the water catchment area.
