The reservoir has a total capacity of approximately 246 cubic hectometers.
It acts as a strategic buffer tank for the Tajo-Segura transfer canal which transports water from central Spain to the arid southeast.
The dam embankment height is approximately 67 meters.
The area is a recognized Important Bird Area (IBA) due to the presence of species like the marbled duck.
The surrounding landscape is composed of Triassic keuper materials and evaporitic rocks, which influence the chemical composition of the water.
Embalse de la Pedrera is a significant reservoir located in the municipality of Orihuela, serving as a critical water storage node in the Vega Baja del Segura region. The site functions as a key component of the Tajo-Segura water transfer system, receiving water through the Carrabals canal. It is surrounded by arid, hilly terrain, making it a distinct feature in the otherwise dry landscape of southern Alicante. The reservoir is not a natural lake but a large-scale hydraulic engineering project managed by the Segura Hydrographic Confederation. Its vast water surface creates a unique microclimate that attracts diverse bird species, particularly migratory waterfowl. The perimeter is characterized by unpaved trails frequently used by local cyclists and hikers for exercise. The reservoir is not designed for recreational swimming or water sports and lacks traditional tourist infrastructure. Its primary purpose remains irrigation supply and water regulation for the surrounding agricultural sectors.
The elevated vantage points along the northern access road offer the best panoramic views of the water surface against the backdrop of the surrounding hills.
Bring binoculars if you have an interest in birdwatching, as the reservoir is a vital sanctuary for aquatic birds.
Wear sturdy footwear suitable for rocky, unpaved trails if you plan to walk around the perimeter.
Carry sufficient water and sun protection, as the area offers almost no natural shade.
Do not attempt to swim in the reservoir or launch private watercraft as it is strictly prohibited for safety and water quality reasons.
No swimming or water-based activities are permitted; stay on designated paths to avoid damaging local flora.
