Are Pearl Lake, Zhaitang Reservoir and Zhuwo Reservoir different names for the same water body?

Pearl Lake and Zhuwo Reservoir are two names for the same place.

Pearl Lake is a lake formed by the construction of Zhuwo Reservoir on the Yongding River. It is named Pearl Lake because of the large number of river mussels growing in the lake. Pearl Lake is located in the west of Zhuwo Village, Yanchi Town, Mentougou District, and in the middle section of Guanting Mountain Gorge on the Yongding River. It was a lake formed when the Zhuwo Reservoir on the Yongding River was built. It was named after the large number and size of river mussels that grew in the lake in the old days. Although pearls are hard to find today, the lake scenery is still alluring, and the name "pearl" has also gained a new interpretation: if viewed from the air, Guanting Reservoir, Zhuwo Reservoir, Luopoling Reservoir, and Barrage Reservoir are like a string of mosaics. The pearls on the Yongding River among the lofty mountains of the Taihang Mountains are dazzling.

Zhaitang Reservoir is located in the canyon southwest of Xizhaitang Village, the main ditch of Qingshui River, Mentougou District, Beijing. Within Qingshui Town, the water source is the Qingshui River formed by Huangtagou, Xiaolongmengou, Lingshan, Longmenjian, Damogou and other streams. The construction of the reservoir began in 1970 and was completed on September 17, 1974. The controlled watershed area is 345 square kilometers. It has a main dam, spillway, water pipeline and flood discharge tunnel. The main dam is a roller-compacted clay sloping wall earth dam with a maximum height of 58.50 meters, a crest length of 380 meters and a width of 5 meters. It has a permanent water storage of about 015 million cubic meters, a water surface of 0.5 square kilometers, and a water depth of about 10 meters, with a total storage capacity of 100 million cubic meters. . There is Malan Terrace nearby.

Zhaitang Reservoir is the largest reservoir in Mentougou District and the most beautiful reservoir with green hills on both sides, birds singing and flowers fragrant. Scenic spots around the reservoir, such as Lingshan Mountain, Baihua Mountain, and Longmen Stream, are only 30 kilometers away from here. National Highway 109 passes through the north bank, making the transportation convenient. In recent years, white swans have frequently visited, and wild ducks and other water crows have nested and multiplied here, bringing vitality to the reservoir. Although Zhaitang Reservoir is currently undeveloped, more than 5,000 people come to fish, camp, and swim every year. This shows that it is imperative to develop Zhaitang Reservoir and realize the transformation of Zhaitang Reservoir from resources to capital. Complying with the situation and following the trend are important steps for tourism to revitalize the town.
