A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.
A spillway is a structure used to provide the controlled release of water from a dam or levee downstream, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.

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.

Water supply and sanitation in Japan is characterized by numerous achievements and some challenges. The country has achieved universal access to water supply and sanitation; has one of the lowest levels of water distribution losses in the world; regularly exceeds its own strict standards for the quality of drinking water and treated waste water; uses an effective national system of performance benchmarking for water and sanitation utilities; makes extensive use of both advanced and appropriate technologies such as the jōkasō on-site sanitation system; and has pioneered the payment for ecosystem services before the term was even coined internationally. Some of the challenges are a decreasing population, declining investment, fiscal constraints, ageing facilities, an ageing workforce, a fragmentation of service provision among thousands of municipal utilities, and the vulnerability of parts of the country to droughts that are expected to become more frequent due to climate change.

The Dayak Desa War or Majang Desa War was an armed uprising by the Dayak Desa tribe, and later Indonesian nationalists, in West Kalimantan against the Japanese Empire and the Dutch East Indies during World War II. The war was initially caused by the local population's opposition against the rōmusha system and disappointment with Japanese occupation. In the initial phase of Japanese occupation, several Japanese companies entered the region to gain natural resources in order to support the Japanese war effort in the Pacific. Occupying Japanese forced locals to work for free for these companies, mainly in coal mining and timber production. After that, a Japanese foreman working in a company wanted to marry the daughter of Pang Linggan, a respected Dayak chief in the region, which caused more tension between locals and the Japanese. Dayak tribes in the region initiated mangkuk merah ritual, as a sign to mobilise men from villages and prepare for war. The Japanese were driven out of the Borneo interior in June 1945, but returned on 17 July and continued until 31 August 1945 when Japanese forces there surrendered and left the region, replaced by Allied forces including the Dutch, who would later be opposed again until recognition of Indonesian independence in 1949.
