Dams in Sri Lanka

Irrigation dams with a length and height of more than and are listed, including all the state-run hydroelectric power stations. Privately owned "small-hydro" facilities (which are limited to a maximum nameplate capacity of ), are not included in this list. Nearly all hydroelectric dams are also used for providing water resource for irrigation purposes, hence for the sake of identifying the hydroelectric dams, any dam with hydroelectric involvement is stated as such in the below table, even if the primary purpose of building the dam is to retain water for irrigation.
