Kanakarayan Aru, a picturesque river in Sri Lanka’s Northern region, stretches approximately 86km, rising from the Eastern Vavuniya District and flowing through the scenic landscapes of Mullaitivu before merging with the Chundikkulam Lagoon. The river is an essential resource for local communities, supporting both agriculture and fisheries, with Paddy cultivation being a key industry in the area. The river’s waters sustain a rich variety of life, including fish species like Tilapia and Catfish, which thrive in its flow. The surrounding vegetation is equally diverse, with Palmyra Palms and Mangroves lining the banks, offering shelter to a wide range of bird species, including Kingfishers and Herons. These ecosystems contribute to the river's ecological significance.
