Senanayake Samudraya is the largest reservoir in Sri Lanka. The reservoir was opened on 28 August 1949 under the Gal Oya Multipurpose Scheme, which was completed in 1953 by D.S. Senanayake. It was built within the 76 tears and 9 more largest reservoirs in Sri Lanka, like Victoria, Randenigala, Moragahakada, Kothmale, etc. There are nine reservoirs bigger than පරාක්රම සමුද්රය built in the last 60 years.
