The useful capacity of the reservoir is 163 hm ³, although its total capacity is 175 hm ³ this is reduced due to the filling of sediments in the background.

Its main tributary is the Guadalén River, which is born to the south of the Montiel Field and crosses Sierra Morena, also highlighting the contribution of the Dañador and Montizón rivers to the main tributary.

Other smaller tributaries that pour their waters on the swamp, or on the Guadalén River before being repressed, are the streams of Galapagar, Oilla, the Navas, the Herrerías and Madriscal, among others.

The Vadamojón Embalse was built to manage the irrigation and ecological flow of the present rivers. It is one of the most important in the Guadalquivir basin, its waters being clear, fresh and with great ecological potential. The landscape of the basin is characterized by its wavy elevations of soft slopes. Its sweet and splattering waters come, among other sources, from the Víboras and San Juan rivers.

Since its implementation in 1997, Vadomojón has become one of the most important free fishing or competition scenarios in both the Sierra Sur region and the Campiña de Baena region in the province of Córdoba.

Vadomojón is a recent reservoir of transparent waters capable of hosting important populations of those fish such as the barbo that inhabited the waters of the Guadaljoz River before the construction of the dam. Other species present are the cachuelo, the boga, the fangs, the tent, the black lubine or the rainbow trout.

A wide variety of fishing methods and techniques can be used in Vadomojón, such as coup, bolognese, English, light or artificial fishing.

One of the most frequent fishing areas in Vadomojón is Caldera, which is accessed by the Víboras River.

Along with the fish, there are birds like flamingos and royal garzas

The Siles dam, which was completed in 2015, receives its water from the Gualimar River and the Carrizas River.
It is a reservoir that receives its water from the Guadalimar River and the Carrizas River, located close to its head and belonging to the Guadalquivir Hydrographic Confederation.

The reservoir is almost entirely the municipal term of Siles (Jaén), although it enters approximately 500 meters in the term of Villaverde de de Guadalimar. It is named after Dam de Siles, when the dam is found in the municipality of the same nomenclature.

The reservoir has an extension of 21.1 ha, with a capacity to store 30 hm ³ of water. The type of dam is from Arc Gravity and was completed in 2015.

With its 53 hectares of capacity and 265 hectares of surface, it is the second largest in the park. It began to be exploited for irrigation and supply in 1972. The maximum water level is 966 m in altitude and the height of the dam on the channel is 43 m.

Located on the outside of the Park, this large reservoir has a storage capacity of 346.5 hm ³ and occupies an area of 1250 ha. It began operating in 1969, with supply for human consumption being the main use of unpackaged water, and irrigation and electricity production being secondary uses.

Its turbines have a production capacity of 15.2 MW / hour. The maximum water level is 594.6 m in altitude and the height of the dam on the channel is 85 m.

Embalse is located in the Sierra de Andújar Natural Park, in the middle of Sierra Morena, known by all Andalusian fishermen for being one of the largest swamps to practice carpfishing. With calm and clean waters, the Jandula flows into it. The most commonly seen species are tents, gypsy barbs and black bass.
