Osum in the context of "Osum Canyon"

The Dassaretii (Ancient Greek: Δασσαρῆται, Δασσαρήτιοι, Dassaretai, Dassaretioi; Latin: Dassaretae, Dassaretii) were an Illyrian people that lived in the inlands of southern Illyria, between present-day south-eastern Albania and south-western North Macedonia. Their territory included the entire region between the rivers Asamus and Eordaicus (whose union forms the Apsus), the plateau of Korça locked by the fortress of Pelion and, towards the north it extended to Lake Lychnidus up to the Black Drin. They were directly in contact with the regions of Orestis and Lynkestis of Upper Macedonia. Their chief city was Lychnidos, located on the edge of the lake of the same name. One of the most important settlements in their territory was established at Selcë e Poshtme near the western shore of Lake Lychnidus, where the Illyrian Royal Tombs were built.

The Dassaretii were one of the most prominent peoples of southern Illyria, forming an ethnic state. They made up the ancient Illyrian kingdom that was established in this region. The weakening of the kingdom of the Enchelei presumably led to Enchelei's assimilation and inclusion into a newly established Illyrian realm at the latest in the 6th–5th centuries BC, marking the arising of the Dassaretii, who appear to have replaced the Enchelei in the lakeland area.

The Devoll (Albanian: Devoll; Albanian definite form: Devolli) is a river in southern Albania.It is one of the source rivers of the Seman. It is 196 km (122 mi) long and its drainage basin is 3,130 km (1,210 sq mi). Its average discharge is 49.5 m/s (1,750 cu ft/s). Its source is in the southwestern corner of the Devoll municipality, close to the Greek border. It flows initially northeast, through Miras, then north through Bilisht, and northwest through Progër, Pojan (in the northern Korçë Plain which was marshy until after the World War II), Maliq, Moglicë, Kodovjat, Gramsh, where it is stowed in a big lake and Gostimë, where it turns south. It joins the Osum near Kuçovë, to form the Seman. The Seman opens into a small delta south of the Karavasta lagoon in the Adriatic Sea.

A number of hydroelectricity plants on the river Devoll are planned or under construction. The Albanian company Devoll Hydropower, owned and operated by the Norwegian power company Statkraft, is building two hydroelectricity plants near Banjë (Banjë Hydro Power Plant) and near Moglicë (Moglicë Hydro Power Plant), with combined capacity 242 MW. The decision whether a third plant near Kokel is to be built, will be taken when the first two dams are completed.

The Seman is a major river in western Albania. It is formed by the confluence of the rivers Devoll and Osum, a few km west of Kuçovë. It is 85 km (53 mi) long (281 km (175 mi) with its longest source river Devoll) and its drainage basin is 5,649 km (2,181 sq mi). Its average discharge is 95.7 m/s (3,380 cu ft/s). It meanders generally westwards through a flat lowland. Near Fier, the Seman receives the Gjanica from the left. It flows into the Adriatic Sea at the southern margin of the Divjakë-Karavasta National Park.

Çorovodë (Albanian definite form: Çorovoda) is a town and a former municipality in Berat County, Albania. At the 2015 local government reform it became a municipal unit and the seat of the municipality Skrapar. It was the seat of the former Skrapar District. The population at the 2023 census was 3,918.

The river Osum passes through the city. Upstream it forms canyons and caves. The river provides opportunities for kayaking and other aquatic sport.
