The name 'Chungpi' (or Zhangpi) refers to the reservoir's historical role in damming water for the surrounding rice paddies of Sanxing.
The lake occupies a former natural swamp area that was artificially expanded to support irrigation needs.
The park features a wooden bridge design that mimics traditional East Asian architecture to blend with the natural surroundings.
The site acts as a micro-habitat for migratory birds passing through the Lanyang Plain during the winter months.
The lake's water levels fluctuate seasonally based on the irrigation requirements of the neighboring agricultural plots.
Chungpi Lake, also known as Zhangpi Lake, is a man-made irrigation reservoir located in Sanxing Township, Yilan County. Originally constructed for agricultural water supply, the lake has been redeveloped into a recreational park surrounded by a wooden boardwalk. The surrounding area is part of a broader ecological corridor that features diverse bird species and endemic aquatic plants. The lake is characterized by its tranquil, reflective waters and a central pavilion accessible via a short walking bridge. Visitors can observe local wildlife, particularly waterfowl, from designated viewing platforms situated along the perimeter trail. The site is a significant component of the local irrigation network in the Lanyang Plain, maintaining a balance between agricultural utility and environmental conservation.
