In the post-independent era, one of the first development projects inaugurated by the Government of Sri Lanka was the development of Gal-Oya Valley, a part of Gal-Oya basin.

An important project undertaken was to cultivate sugar cane. The decision to grow sugar cane was based on three factors: availability of mass scale flat lands, sufficient water from Inginiyagala tank, and the fact that for the traditional paddy farmer, shifting to sugar cane was not an insurmountable problem.
