696:. This is because it flows into the sea through a small opening in a valley. Although due to sedimentation, this delta is now only very partially inverted, with the valley now mostly filled with sediment. The delta is about 15 km (9 mi) wide and 25 km (16 mi) long, but its exit into the sea is only 2 km (1.2 mi) wide. It thus forms a large lagoon with large and very shallow sand banks which go uncovered during low tides. The delta used to be even bigger thousands of years ago.

of great ecological interest. Some of them have been legally protected, such as the Alto Tajo
Natural Park (Guadalajara and Cuenca), the Monfragüe National Park (Cáceres), and the Tagus Estuary Natural Reserve, near Lisbon. Around the course of the river, four endangered animal species live: the Iberian lynx, the Spanish imperial eagle, the black stork, and the black vulture.

The banks and areas of influence of the Tagus are home to relevant flora and fauna, representative of the central region of the
Iberian Peninsula. The high degree of depopulation in some areas integrated into its basin, such as its upper and middle-lower course, has allowed the preservation of places

The Tagus River originates at an elevation of 1,593 meters above sea level in a place known as Fuente García, within the municipality of Frías de
Albarracín in Teruel, Spain. Its source is located between the Muela de San Juan (1,830 m) and Cerro de San Felipe (1,839 m), in the Sierra de Albarracín,

In addition to its geographical relevance, the Tagus has great historical importance, resulting from its connection with Toledo and Lisbon, two of the cities with the greatest weight and historical journey in the
Iberian Peninsula. The first was built on a hill about 100 m high, around the meander

The nearly 100 km (60 mi) of the Alto Tajo canyon as it passes through the natural park of the same name offer one of the best options for practicing whitewater canoeing in the central peninsula. Several adventure companies offer this activity in the vicinity of Poveda de la Sierra and

The hydrological regime of the Tagus is determined by the rain and snow variations typical of the central region of the
Iberian Peninsula, especially in reference to the mountain formations integrated here. The river's major floods usually occur from January to April, with an absolute maximum in

The Tagus basin has a total area of 80,600 km (31,100 sq mi). It is the most populated basin in the
Iberian Peninsula, with more than ten million inhabitants. It includes the Madrid metropolitan area and the Lisbon region. The Tagus basin has a total reservoir capacity of around

The river flows through Spain for 816 km (507 mi), passing through four autonomous communities (Aragón, Castilla-La Mancha, Madrid, and
Extremadura) and a total of six provinces (Teruel, Guadalajara, Cuenca, Madrid, Toledo, and Cáceres). After forming a 47 km (29 mi) border

This regime has been altered in the second half of the 20th century as a result of the construction of different engineering works, aimed at regulating its basin for five main uses: drinking water supply, irrigation, water diversion to an external basin (that of the Segura River), electricity

From the Late Middle Ages, the mouth of the Tagus articulated an intense commercial activity between
Northern Europe and the Mediterranean. From the Renaissance, it was the main communications hub of the Portuguese Empire, which extended through America, Africa, and Asia.

between Spain and
Portugal, it enters Portugal. In Portugal, it flows for 145 km (90 mi) through the traditional regions of Beira Baixa, Alto Alentejo, Ribatejo, and Estremadura, which include the districts of Castelo Branco, Portalegre, Santarém, and Lisbon.

This results in a very irregular course, with strong flow oscillations. As it passes through Alcántara (Cáceres), these range from 350 m/s (12,000 cu ft/s) in
February and March to 11 m/s (390 cu ft/s) in August and September.
