The river flowing and entering the Gulf of Mannaar at Mu'l'likku'lam is the boundary between the Northern and the North Western Provinces. The Vilpattu reserved forest south of the boundary was scattered with a number of Tamil villages before it was declared a reserved forest in 1903. The Tamil territory was contiguous up to Negombo in the Western Province at that time, before the Sinhalicisation of the Tamil Catholics of today's Puththa'lam and Gampaha districts.
