The Gal Oya Dam (also known as Inginiyagala Dam) is an embankment dam in the Uva Province of Sri Lanka. The dam creates one of the largest reservoirs in the country, the Gal Oya Reservoir. Water from the reservoir is used primarily for irrigation in the Uva and Eastern provinces, in addition to powering a small hydroelectric power station. Construction of the dam and reservoir began in August 24, 1949, completing four years later in 1953.[1]
