Project Description

The Niaozuitan Artificial Lake Project is an important water resource construction under the Water Resources Agency. Construction began in 2019, with the first lake area completed in 2021 and water storage initiated the same year. In 2023, the project played a critical role in drought relief by supplying water. By 2024, six lake areas were fully impounded, and the project was officially completed in January 2025.
Construction Duration: 5 years (2019–2025)
Effective Storage Capacity: 14.5 million tons, sufficient to supply water for 1 million people for 58 days
Daily Water Supply: 250,000 tons (210,000 tons to Changhua, 40,000 tons to Caotun)

Project Overview and Features

The Niaozuitan Artificial Lake, located beside the Wu River in Caotun Township, Nantou County, is composed of six lake areas that resemble a bird’s beak when viewed from above. The lake covers a surface area of 110 hectares, about one-seventh the size of Sun Moon Lake. At full capacity, it can store 14.5 million tons of water, providing water for 1 million people for 58 days, making full use of the abundant water resources of the Wu River.
The artificial lake mainly supplies domestic water to the Changhua and Caotun areas, with an estimated daily supply of 210,000 tons to Changhua and 40,000 tons to Caotun. Previously, Changhua relied heavily on groundwater extraction and water allocation from Taichung and Yunlin. With the new lake, about half of Changhua’s daily water demand can now be met, effectively reducing excessive groundwater pumping that causes land subsidence along the coastal areas of Changhua, while strengthening regional water supply resilience.

Project Benefits

Stabilizes domestic water supply, Mitigates land subsidence, Promotes local tourism
