A dam is a barrier that stops or restricts the flow of 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 water or for storage of 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.
Arenal Volcano is an active andesitic stratovolcano in north-western Costa Rica around 90 km (56 mi) northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna.

Costa Rica is divided into three major drainage basins encompassing 34 watersheds with numerous rivers and tributaries, one major lake used for hydroelectric generation, and two major aquifers that serve to store 90% of the municipal, industrial, and agricultural water supply needs of Costa Rica. Agriculture is the largest water user demanding around 53% of total supplies while the sector contributes 6.5% to the Costa Rica GDP. About a fifth of land under cultivation is being irrigated by surface water. Hydroelectric power generation makes up a significant portion of electricity usage in Costa Rica and much of this comes from the Arenal dam.

Renewable energy in Costa Rica supplied about 98.1% of the electrical energy output for the entire nation in 2016. Fossil fuel energy consumption in Costa Rica was 49.48 as of 2014, with demand for oil increasing in recent years. In 2014, 99% of its electrical energy was derived from renewable energy sources, about 80% of which from hydroelectric power. For the first 75 days of 2015, 100% of its electrical energy was derived from renewable energy sources and in mid 2016 that feat was accomplished for 110 consecutive days despite suboptimal weather conditions. As a country, Costa Rica has a geographic advantage over others in that its high concentration per capita of rivers, dams, and volcanoes allows for a high renewable energy output. In addition, Costa Rica is the fourth highest nation in terms of rainfall per capita: it receives an average of 2,926mm of precipitation per year. As a smaller nation with a population of only 5 million and no major industry, the need for strong energy infrastructure is less than for larger countries of higher population density. The 1948 elimination of the military of Costa Rica freed up millions of dollars from the government defense budget which are now invested in social programs and renewable energy generation. As president of Costa Rica in 1948, José Figueres announced that the nation's former military budget would be refocused specifically in healthcare, education, and environmental protection.
