Dams and Reservoirs in Portugal
Portugal is home to a variety of dams and reservoirs, each serving critical roles in water supply, hydroelectric power generation, flood control, and irrigation. The geographic distribution of these structures is diverse, spanning from the mountainous regions in the north to the plains in the south.
Notable Dams and Reservoirs
Alto Tâmega Dam
The Alto Tâmega Dam is part of a larger hydroelectric complex located in the northern region of Portugal. This project is vital for both energy production and regional water management.
Alqueva Dam
The Alqueva Dam, situated on the Guadiana River, is renowned for creating one of the largest reservoirs in Western Europe. It plays a significant role in agricultural irrigation, water supply, and renewable energy.
Aguieira Dam
Located on the Mondego River, the Aguieira Dam is a key component of the region's water system, contributing to both water storage and hydroelectric power generation.
Alto Lindoso Dam
The Alto Lindoso Dam is positioned near the border with Spain and is a major supplier of hydroelectric power, benefiting from its strategic location in the mountainous north.
Carrapatelo Dam
The Carrapatelo Dam is constructed on the Douro River, and it is one of several dams that facilitate navigation and energy production along this major waterway.
Cabril Dam
Located on the Zêzere River, the Cabril Dam is crucial for flood management and electricity generation. It also supports local agriculture through water supply.
Hydroelectric Power Stations
Hydroelectric power stations are integral to Portugal's energy infrastructure. They harness the kinetic energy of flowing water to generate electricity, contributing to the country's renewable energy goals.
Santa Luzia Dam
The Santa Luzia Dam features a concrete arch design, utilizing its location on the Zêzere River for power generation and water supply.
Marechal Carmona Dam
The Marechal Carmona Dam, also known as the Idanha-a-Nova Reservoir, is located on the Ponsul River. It is an essential structure for both power generation and regional water management.
Regional Distribution
These dams and reservoirs are categorized by NUTS Regions and Subregions across Portugal, reflecting their strategic importance in different geographic and administrative areas.
Cross-Border Structures
Aldeadávila Dam
While primarily a Spanish facility, the Aldeadávila Dam straddles the border between Spain and Portugal on the Duero River. It is a monumental example of cross-border cooperation in water management and energy generation.
Covão dos Conchos
The Covão dos Conchos, though not a typical dam, features a spectacular bell-mouth spillway in the Serra da Estrela mountains, designed to divert water into the Lagoa Comprida.
