In 1973~1977 years, the average daily flow of the spring group is 36 thousand and 300 cubic meters, the largest is 104 thousand and 500 cubic meters, the smallest is 6 thousand and 300 cubic meters. Spring water flows into the West River.
Baotu Spring is located in front of Baotu Spring Yuan Yuan Yuan hall. The stone was built around the shore in 1931. After several changes, this spring pool is rectangular, 30 meters long, 18 meters wide and 2.2 meters deep. The north is facing the Yuan Yuan hall, the west side is the Guanlan Pavilion, the East shelf is crane bridge, and the south is a long corridor. The inscription of "famous spring tablet", Ming Yan Bi's "seventy-two springs poem" and Qing Hao Zhi Gong "seventy-two Quan Ji" are all catalogued. The spring has an elevation of 26.49 meters, a constant temperature of 18 degrees, and a maximum inrush of 162 thousand cubic meters per day. When the underground water level is lower than the exposed elevation, the spring will cease to surge. According to Qing Dynasty Qianlong "county records two", Ming Wanli forty-six years (1618), Chong Zhen fourteen years (1641) had dried up. Since 1972, it often stops. From May 1986 to August 26, 1987, the surge lasted for 15 months, and from August 1988 to August 1990, the flow lasted for 24 months. Baotu Spring is the source of ancient water. In ancient times, "song" was called "Baotu Spring" in the Song Dynasty. Also known as "e Ying Shui", "hot spring", "Quan Quan", "waterfall spring", "three streams of water" is another name or commonly known. Spring and Autumn Annals: Lu Huan Gong, eighteen years (694 BC) in spring, "Qi Qi Hou Hou Yu". The Northern Wei geographer Li Dao Yuan "Shui Jing Zhu Ji Shui" contains: "Shui Shui county, Gucheng southwest." It is common to say that e Jiang is also a water source. The Northern Song Writer Zeng Gong said in the two notes of Qi State, "the name of it is said to be" the spring of the sudden leap "," the spring of the spring of the spring of the spring, and the spring of the spring by Chang Rong. " In the same period as Baotu Spring (September 1987), Zeng Gong, Liu Zhao, called it "Quan Quan" according to the phrase "Book of Songs boiling". Yuan Haowen, the golden man, is also known as "waterfall spring" in "Ji'nan Xing Ji". The local people are gushing out of their caves, forming three springs, so they are commonly called "three strands of water". According to the exploration of the hydrogeological department, the geological condition of the Baotu Spring is: the ground surface is 8 meters down, the Quaternary gravel, the clay layer, and the Ordovician dolomitic limestone 8~80 meters. In marble above 30 meters, cracks and karst caves are specially developed. These fractures and karst caves become the channel of groundwater concentration and rise. The rising groundwater flows out of the ground from two hole gaps between 2 and 3 meters. It becomes the South and north two of the three springs of Baotu Spring. Baotu Spring, three shares stand side by side, "the fountains are excited, and the water rushes round". In the Qing Dynasty, Liu Yi's Travels of the old remnant included: "the three big springs come out from the bottom of the pool and rise to two or three feet high. According to native people's cloud, "five or six feet high". According to the spring water of Ji'nan published by the Geological Publishing House in 1982, the spring of Baotu Spring can still run two feet high in 1959. Because of the spectacular momentum, it is known as the "jumping out of the sky". The ancients were listed as one of the eight scenes of Ji'nan. Because of the unusual landscape, they were praised by scholars of the past dynasties, such as Zeng Gong, Yuan Haowen, Zhao Mengtiao, Zhang Yanghao, Wang Shouren, Wang Shizhen and Pu Songling. In the Qing Dynasty, Emperor Kangxi and Emperor Qian Long also carved their stones into stone.
