The Thune Dam is a dam on the Thune River in Botswana that was under construction in 2012. It has a planned capacity of 90,000,000 cubic metres (3.2×109 cu ft).
The dam is located on the Thune river upstream from its confluence with the Motloutse. The dam is situated in relatively flat country, and will have an average depth of about 15 metres (49 ft). Given the hot, dry climate, evaporation loss is a serious concern. Various ways to reduce such loss have been considered but rejected. The dam will be an earthfill clay-core structure. It will be 33.6 metres (110 ft) high, with a 1.7 kilometres (1.1 mi) long wall and a 90,000,000 cubic metres (3.2×109 cu ft) capacity.
The dam will supply drinking water to several villages in the Bobirwa area, and irrigation water to an agricultural project near Mathathane.Once complete, water will be delivered to the villages of Bobonong, Motlhabaneng, Mathathane, Tsetsebjwe, Mabolwe, Semolale, Gobojango, Lepokole and Molalatau.
A stakeholders workshop was held in September 2009 at Molalatau Secondary School Hall, where the Minister provided information and answered questions. He warned that, although the dam would bring large benefits, there would also be problems during the construction process such as an influx of illegal immigrants, crime and sexual problems such as HIV/AIDS and teen pregnancies.
The dam site was handed over to the contractor, Zhon Gan Engineering and Construction, on 30 April 2010.The project was due to be completed in April 2013. The water treatment plant and pipelines could be delayed until 2014 due to funding problems. In July 2010 it was reported that work on the dam site had halted since an incident in which a worker was killed a month earlier. Bush clearing had started in the site so surveying could be undertaken, but the project was behind schedule. A ground-breaking ceremony was held in September 2010, attended by Ponatshego Kedikilwe, Minister of Minerals, Energy and Water Resources.
As of March 2011, Thune Dam was just 38% complete. Delays had been caused by floods, and there were problems with construction of accommodations and with licenses.
The Ilısu Dam is a concrete-face rock-fill dam on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey. It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage. When operational, the dam will support a 1,200 MW power station and will form a 10.4 billion m3 reservoir. Construction of the dam began in 2006 and was originally expected to be completed by 2016. As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power. The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region. Because of this, the dam lost international funding in 2008. Kurdistan Workers' Party terrorists have also attacked infrastructure associated with the dam which led to construction delays. The dam began to fill its reservoir in late July 2019. Due to rainfall, the dam has achieved water levels up to 100m above the river bed and stored 5 billion cubic meters of water. The water level has reached to the elevation of 498.2m on 1 April 2020.

The other four dams are Dospat Dam, Teshel Dam, the Vacha Dam and the Krichim Dam.
The Samanala Dam is a dam primarily used for hydroelectric power generation in Sri Lanka. Commissioned in 1992, the Samanalawewa Project is the third-largest hydroelectric scheme in the country, producing 405 GWh of energy annually. It was built with financial support from Japan and the United Kingdom. It is notable for a large leak on its right bank. Power production continues as planned despite the leakage, and the water from the leak now provides two thirds of the water issued by the reservoir for agriculture in downstream areas.
The Sulejowski Reservoir is an artificial lake, a reservoir created by a dam, built in the years 1969-1974 in the Łódź Voivodeship. The aim of this reservoir was to supply fresh drinking water to the city of Łódź and Tomaszów Mazowiecki. At full capacity the reservoir contains up to 95,000,000 cubic metres (77,000 acre⋅ft) of water and has an average depth of 3.3 metres (11 ft).
The Siah Bisheh Pumped Storage Power Plant, also spelled Siyāhbisheh and Siah Bishe, is located in the Alborz Mountain range near the village of Siah Bisheh and 48 km (30 mi) south of Chalus in Mazandaran Province, Iran. The power plant uses the pumped-storage hydroelectric method to generate electricity during periods of high energy demand, making it a peaking power plant, intended to fulfill peak electricity demand in Tehran 60 km (37 mi) to the south. When complete it will have an installed generating capacity of 1,040 megawatts (1,390,000 hp) and a pumping capacity of 940 megawatts (1,260,000 hp). Planning for the project began in the 1970s and construction began in 1985. It was delayed from 1992 until 2001 and the first generator went online in May 2013. The remaining generators were commissioned by 1 September 2015. The power plant is the first pumped-storage type in Iran and will also use the country's first concrete-face rock-fill dam – two of them.

Completed in 1985, with a length of 373 metres (1,224 ft), the dam created a multipurpose reservoir covering 28.3 km2 (10.9 sq mi) in the scenic hills of the Western Ghats.
The Shuangjiangkou Dam, also referred to as Shuang Jiang Kou, is an embankment dam currently being constructed on the Dadu River in Sichuan Province, China. When completed, the 312-metre-tall (1,024 ft) dam will be the tallest dam in the world. Preliminary construction began in 2008 and the entire project was expected to be complete in 2018. By April 2011, over 200,000,000 m3 (261,590,124 cu yd) of material had been excavated from the construction site. In March 2013, China's Ministry of Environmental Protection approved construction on the dam's superstructure and associated facilities. The government acknowledged that the dam would have negative impacts on the environment but that developers were working to mitigate them. The dam is being built by the Guodian Group at a cost of US$4.02 billion. The entire construction period is expected to last 10 years. All turbines are expected to be commissioned by 2023.
