With the establishment of modern water supply systems, these old ponds fell into disuse. And with the rising price of land, the ponds were zoned for other uses or became filled with garbage. With the added impact of wastewater pollution and other factors, the water plants in these ponds quickly began to disappear.
隨現代化的水利系統建構，陂塘大半已失去灌溉功能，加上地價飆漲，原生陂塘或因變更地目、或被回填垃圾，加上工業廢水污染及外來種入侵等因素，陂塘與生存其中的水生植物正快速消失。
