Batllava Lake, reservoir in Podujevë, Kosovo

Batllava Lake is an artificial reservoir in the Llapi region of northeastern Kosovo, about 13 km from Podujevë and 30 km from Pristina. It stretches roughly 6 km west to east, reaches a width of up to 700 m and a depth of 48 m, and is held by a 40.5 m dam at its western end. The Batllava River feeds it.

Construction of the dam on the Batllava River began in 1961 and was finished by 1965, creating a reservoir of 3.29 km² with a 40.5 m high dam. It first supplied water to the coal-fired power plants in Obiliq, which later switched to Ujman Lake. The lake now feeds the regional water company Prishtina and the municipalities of Podujevë, Pristina and Obiliq.

The lake is named after the nearby village of Batllava. Its water is treated at a plant on a nearby hill and then distributed through two pipes: one to Pristina at 1,000 litres per second, the other to Podujevë at 250 litres per second. The water utility draws 34 million tonnes from the lake each year.

The lake is easily accessible by local roads and has gently sloped shores that make it simple to reach the water. It is best to bring your own supplies if you plan to spend extended time here, as there are no major facilities nearby, though the area offers basic spots for picnicking and camping.

The lake's dam, 40.5 m high, stands at the western end, while bathers use the eastern end. Since 2021 the Kosovo Swimming Federation has held an international marathon here; in the "Kosova 2021" edition, 27 swimmers from Kosovo, Albania and North Macedonia raced over 4.2 km.
