context_page_description: The Eastern Zhejiang Canal is located in Zhejiang province, China. Its west end is in Xixing Street, Binjiang District, Hangzhou City, crossing Cao'e River and Shaoxing City to its east end, the Yong River estuary in Ningbo City. The canal is 239 kilometres long. Early canal construction took place in the Shanyin old canal in Shaoxing City, in the Spring and Autumn period. In the third century AD, an official named He Xun supervised the construction of Xixing Canal, establishing the complete Eastern Zhejiang Canal.
  In the Southern Song dynasty, the capital was established at Linan, which meant that the Eastern Zhejiang Canal became an important shipping channel. From the Yuan Dynasty to the Qing Dynasty, the Eastern Zhejiang Canal lost its privilege but still remained navigable. In recent years, because of newer modes of transportation, the canal has been gradually replaced. The reconstruction of the canal began in 2002, by 2007 it was partially navigable, and the renovation project finished in 2009, though the Ningbo section was not navigable until the end of 2013.
context_section_description: The Eastern Zhejiang Canal is made up of many natural rivers. To maintain the stable water levels and benefit agriculture along the banks, numerous water conservancy facilities were constructed along the canal. These are primarily composed of barrages, dams and gates. Among these, significant ones can be found on the central canal and tributaries of the canal such as the Yongxing Gate (located in Xiaoshan District, Hangzhou, Zhejiang Province), the Caoe Barrage, the Lianghu Barrage, the Tongming Barrage, the Qingshui Gate (all located in Shangyu District, Shaoxing, Zhejiang Province), Doumen Gate, the Yunlou Xiaba Dam (both located in Yuyao, Zhejiang Province) and the Xidu Barrage (located in Ningbo, Zhejiang Province). 
  The Yongxing Gate, which is also called the Longkou Gate, is located in Xixing. In the past, it was ten li (a Chinese unit of length, one li = 1/2 kilometre) away from Xiaoshan County and served as the western starting point of the canal. It used to be a barrage, which was then transformed into a gate in the fifteenth year during the reign of Wanli emperor to resist the tides from the Qiantang River (Chinese: 钱塘江). You can still see its remains today.
  The Caoe Barrage lies on the west bank of the Caoe River. In ancient times, it was 90 li away from Shaoxing city and used to be a gate while it functions as a barrage nowadays. A ship lift now operates on the barrage.
  The Lianghu Barrage, which lies on the east bank of the Caoe River, used to connect the Caoe River and the Sishili River. It moved multiple times in history and the current location is in Wailianghu Village, Lianghu Town. Due to the reconstruction of the canal, this barrage is not in use any more.
  The Tongming Barrage is located in Fenghui Town, Shangyu District, Shaoxing. There are two barrages near it, named the North Barrage and the South Barrage respectively.
  The Qingshui Barrage is located in Haoba town, Shangyu District, Shaoxing. During the period of Jiatai in the Southern Song dynasty, the Qingshui Sluice Gate was built, with a sluice gate beneath. Since then, it was reconstructed during every dynasty.
  The Doumen Barrage is located in Yuyao. Its history can be seen in record from the Southern Song dynasty. Its old barrage still remains today but is of no use. In 1983, the ship lift was installed.  Its history is a reflection of the continual evolution of the canal's water conservancy facilities.
  The Xiaba Dam is located in Yuyao and is also named Dajiangkou Dam. It was 40 li away from Yuyao county in ancient times and was a necessary route to take from Ningbo to Shaoxing, connecting the Shibali River and the Yao River. Its remains still exist today and a ship lift was built later.
  The Xidu Barrage also called the Daxi Dam, which is located in Haishu District, Ningbo. It was originally built in the Song dynasty while the current construction was built during the period of Zhengtong in the Ming dynasty. As a connection of the Yao River and the Xitang River, it served as an important path from Mingzhou to the capital in ancient times. It has been preserved well.
  Currently, these constructions are included in the sixth batch of historical and cultural sites protected at the provincial level in Zhejiang Provence under the following projects – The Water Conservancy and Shipping Facilities of the Qiantang River and Canal Ports, The Water Conservancy, Shipping and Service Facilities of the Caoe River's Ports, Relic Sites Group of the Tongming Barrage, The Water Conservancy and Shipping Facilities from Yiting to Wufu, The Qingshui Gate and Management Facilities, The Water Conservancy and Shipping Facilities of the Yao river and Relevant Heritage Groups etc.
