Victoria Dam (Sinhala: වික්ටෝරියා වේල්ල Viktoriya Vella) is an arch dam located 130 mi (209 km) upstream of the Mahaweli River's mouth and 4 mi (6 km) from Teldeniya. It is named in honour of Queen Victoria of the United Kingdom. Its main purposes are irrigation and hydroelectric power production.
Most fish populations are expected to make a return to the river (Table 1). While fish may return to the river as soon as a year after the removal is complete, [10] it may take 15 to 20 years for the river to fully return to its pre-dam conditions. [6] The ultimate goal of the dam removal is restoring the river to a nearly pristine state. [14]
Lake Chelan Dam officially known as the Lake Chelan Hydroelectric Project is located approximately 32 miles (51 km) north of the city of Wenatchee in Chelan County. The dam is located at the lower or southeasterly end of 50.4 miles (81.1 kilometres) [ 5 ] long Lake Chelan , and is within the limits of the city of Chelan .
The St. Margaret's Bay Hydroelectric System consists of three hydroelectric power plants (two collocated in the same building) and the related lake, dam, and river systems driving them. The system is situated within both Lunenburg County and the Halifax Regional Municipality , beginning approximately 2.5 km (1.6 mi) east of the Head of Saint ...
The Report of the World Commission on Dams also includes in the "large" category, dams which are between 5 and 15 m (16 and 49 ft) high with a reservoir capacity of more than 3 million cubic metres (2,400 acre⋅ft). [45] Hydropower dams can be classified as either "high-head" (greater than 30 m in height) or "low-head" (less than 30 m in height).

Irrigation dams with a length and height of more than 100 m (330 ft) and 10 m (33 ft) are listed, including all the state-run hydroelectric power stations.
Hydroelectric power stations continued to become larger throughout the 20th century. Hydropower was referred to as "white coal". [19] Hoover Dam's initial 1,345 MW power station was the world's largest hydroelectric power station in 1936; it was eclipsed by the 6,809 MW Grand Coulee Dam in 1942. [20]
Hydropower technology and attitude began to shift in the second half of the 20th century. While countries had largely abandoned their small hydropower systems by the 1930s, the smaller hydropower plants began to make a comeback in the 1970s, boosted by government subsidies and a push for more independent energy producers.
