The waters. Springs, rivers, lakes. – The abundance of rains and snows explains the richness of the springs, which is a feature common to all of Albania, albeit to varying degrees, as their distribution is linked to the alternation of layers of different permeability. The springs feed a large number of mountain streams, which then merge into large river arteries. The waterways of Albania have some fundamental characteristics in common with those of the rest of the Balkan Peninsula (v.). The immaturity nature of the Albanian hydrographic network should be generally noted; the transversal valleys above all have a youthful aspect and an irregular profile: narrow and wild gorges alternate with sections of wide valleys where the river wanders capriciously; the examples of recent catches are very numerous; the one operated by the Shkumbî of a part of the ancient lake basin of Elbasan, whose waters once deviated to the SW, can be considered as typical. by means of the Devoll. With regard to the regime of the rivers, the fact that the summer months are decidedly dry has great influence, while in the autumn, and also, albeit a little less, in the spring, abundant rains fall. The rivers are therefore, also in this respect, very irregular: almost dry in summer, they swell in autumn and spring and are subject to disastrous floods, during which, in the plains, they largely flood the surrounding countryside. Everyone would need some adjustment work. Traversing, in the middle and lower course, areas where easily erodible rocks (clays, sands) prevail, they are loaded with transport materials and turbid,
According to indexdotcom, the following eight can be considered as Albanian rivers, whose lengths were calculated with a curvimeter on the map at 200,000:
- La Boiana, in Albanian Bunë (km. 44), emissary of Lake Scutari.
- The Drin (km. 280), the largest Albanian river, whose main branch, or black Drin, is the emissary of the lake of Ochrida (see drinand ochrida).
- The Mati (km. 104) which originates from Mal’i Lopës and runs first as a mountain torrent towards the NE. a narrow gorge the mountainous wall that stretches between Tirana and Alessio, and flowing into the plain ends with a vast delta that tends to join up with that of the Drin in the large wooded area called Bregumatia (Bregu i Matit).
- The Ishmi (km. 70), a coastal river formed by three streams coming from the mountain of Tirana.
- The Arzen (km. 90), which drains the S. part of the Mountain of Tirana, a stream poor in water that flows into N. del C. Pali.
- The Shkumbî (km. 147), the central river of Albania, which has its sources at a very short distance from the lake of Ochrida (see shkumbî).
- The Semeni (km. 252), name that the Albanians attribute to the lower trunk of the Devoll, after its meeting with the Osum.
- The Voiussa or Vijosë (km. 237) which arises from Pindus in a territory that does not belong politically to Albania and crosses the southern part of the country in all its extension (see Voiussa).
As already mentioned, large lake basins still existed in Albania in the Plistocene. In N. the lake of Scutari (v.) Is itself the remnant of a larger lake area; in the center, the great Elbasan basin emptied itself, following the postpliocene uplift, giving way to a basin still filled with clearly terraced lake deposits. To the SE., The immense expanse of lakes, located on the border of Macedonia, has left three residues in the Prespa lakes, the largest in the Balkan Peninsula (v.), Of Ochrida (v.) And in the Maliq lake, a shores uncertain that occupies the northern part of the plain of Còrizza, crossed by the Devoll; surrounded by reeds and alder and poplar woods, it has a very variable area according to the seasons, but a small depth.
