Eritrea, a country located in the Horn of Africa, is largely arid and semi-arid, making water resource management crucial for its agriculture, drinking water supply, and overall development. The country relies on a network of dams and reservoirs to store and regulate water, primarily for irrigation and drinking water rather than electricity generation. This article examines the top 10 largest dams in Eritrea, highlighting their location, capacity, and their role in supporting Eritrea’s growing needs for sustainable water management.
1. Tekezé Dam (Shared with Ethiopia)
- Location: Border between Eritrea and Ethiopia
- River: Tekezé River
- Power Output: 300 megawatts (MW)
- Capacity: 9.3 billion cubic meters
The Tekezé Dam, located on the Tekezé River near the border with Ethiopia, is one of the largest dams affecting both Eritrea and Ethiopia. While primarily benefiting Ethiopia’s energy sector by generating 300 MW of hydroelectric power, this dam’s reservoir also influences water availability in nearby Eritrean regions. The dam provides water for irrigation and flood control, playing an essential role in local agriculture.
2. Gerset Dam
- Location: Gash-Barka Region
- River: Gash River
- Power Output: None
- Capacity: 25 million cubic meters
Gerset Dam is one of the largest dams in Eritrea, primarily used for irrigation. The dam provides water for surrounding farmlands, helping to support agricultural productivity in one of the most fertile regions of the country. It plays a key role in supporting Eritrea’s efforts to improve food security and crop production.
3. Fanco Dam
- Location: Debub Region
- River: Seasonal Rivers (Wadis)
- Power Output: None
- Capacity: 20 million cubic meters
Fanco Dam is designed to capture seasonal water from the region’s wadis, which are dry riverbeds that flood during the rainy season. The dam is essential for storing water for agriculture and drinking purposes, providing a steady water supply during the dry season. Fanco supports irrigation and improves access to water for nearby communities.
4. Tokombia Dam
- Location: Gash-Barka Region
- River: Gash River
- Power Output: None
- Capacity: 18 million cubic meters
Tokombia Dam is an important dam for agricultural irrigation in Eritrea’s Gash-Barka region. It helps regulate the flow of the Gash River and stores water for use during the dry months. The dam also supports local farmers by ensuring a consistent water supply for crop production, which is crucial in this primarily agricultural region.
5. Kerkebet Dam
- Location: Anseba Region
- River: Anseba River
- Power Output: None
- Capacity: 16 million cubic meters
Kerkebet Dam is located on the Anseba River and serves as a significant water reservoir for the surrounding areas. Its primary function is to provide water for irrigation and livestock farming. In a region that often experiences water shortages, Kerkebet Dam plays a vital role in ensuring water availability throughout the year.
6. Bademit Dam
- Location: Gash-Barka Region
- River: Seasonal Rivers
- Power Output: None
- Capacity: 15 million cubic meters
Bademit Dam helps capture seasonal rains and store water for irrigation and domestic use in Eritrea’s Gash-Barka region. The dam is a key part of the local infrastructure, providing water for agriculture and supporting the livelihoods of communities dependent on farming. It also helps reduce the impact of seasonal flooding.
7. Adi Halo Dam
- Location: Central Region (Maekel)
- River: Seasonal Streams
- Power Output: None
- Capacity: 10 million cubic meters
Adi Halo Dam is a smaller dam designed to capture water from seasonal streams in the central highlands of Eritrea. It supports agricultural activities and provides water for nearby towns and villages. The dam is also used to improve irrigation practices, enabling local farmers to grow crops more consistently throughout the year.
8. Tsaeda Emba Dam
- Location: Southern Region (Debub)
- River: Seasonal Streams
- Power Output: None
- Capacity: 8 million cubic meters
Tsaeda Emba Dam is part of Eritrea’s efforts to improve water storage and irrigation in its southern region. This dam helps capture seasonal rainfall and stores water for agricultural use during the dry season. It is crucial for supporting crop production and ensuring that local farmers have access to reliable water supplies.
9. Hagaz Dam
- Location: Anseba Region
- River: Anseba River
- Power Output: None
- Capacity: 7 million cubic meters
Hagaz Dam, located on the Anseba River, is vital for irrigation and water supply in the arid Anseba region. The dam supports agriculture, providing water for small farms and livestock. It also helps mitigate the effects of drought by ensuring water is stored and available during periods of water scarcity.
10. Logo Dam
- Location: Southern Region (Debub)
- River: Seasonal Streams
- Power Output: None
- Capacity: 5 million cubic meters
Logo Dam captures water from seasonal streams in Eritrea’s southern highlands. The dam plays a key role in providing water for irrigation and ensuring a steady supply of water for both domestic and agricultural use. Its role in supporting local farming communities makes it an important part of Eritrea’s water infrastructure.
Conclusion
Eritrea’s dams are essential for managing the country’s scarce water resources, supporting agriculture, and ensuring a reliable water supply for domestic use. Although the dams in Eritrea are smaller compared to those in neighboring countries, they play a crucial role in improving food security, supporting local farmers, and regulating water availability in a largely arid environment. As the country continues to develop, expanding its water infrastructure will be key to sustaining economic growth and improving the livelihoods of Eritrean communities.
