|Waterscapes of Lanyang / The Scenic Beauty of Yilan|
|Yilan enjoys plentiful rainfall and is one of the few counties in Taiwan that has no need for reservoirs. Deep beneath Yilan lies a huge unseen reservoir and when the water travels, it spins a colorful yarn about the breathtaking waterscapes of Yilan.|
Springs are an important water resource for the Yilan plain. The ponds found on the Yilan plain were largely formed from such sources of water. The spring recharge area of the groundwater is located between west of Dazhou and the plain fanhead; areas with an elevation between 7-15 meters are most suited to the formation of groundwater.
The groundwater flows through faults or fissures into deeper areas where it is heated. This creates a pressure difference and causes the water to once again pass through the fissures and move to the surface where it forms hot springs.
Groundwater seeps deep underground through fissures, where it pools and dissolves large amounts of minerals and carbon dioxide (CO2), during the Japanese occupation colonial era, the Su’ao Cold Springs were used to make Yokan (a Japanese-style bean jelly) and Ramune (also known as marble soda). For the local people, taking a dip in the springs was a good way to cool off in the blistering summer heat.
