It was a badly managed parked in the 70s and 80s and nowadays is getting better, better managed, but I wished personally, they provide even more detail of the history of this park, the park, is built on a natural spring, the spring water flows strongly , survived through many droughts and is the source of at least two major rivers in Taoyuan city, provided water supply for agriculture for Taoyuan region, this is a big deal as Taoyuan region has much less rivers than most other regions in Taiwan, water supply is essential, and make this location important and an essential for farmers. Once a year they drain the lake to clean the bottom of the lake but the springwater continuous to flow non stop
