- Notes
- Rambakan Oya (Ampara range), one of the Irrigation Department's major reservoirs. Effective storage is gross storage less dead storage. % of active storage (gross capacity less dead storage): the Department's own figure from the daily sheet; before it, computed the same way from the season tables' effective storage. Daily from the 2020/21 Maha season (major) or 2023 Yala (medium), from the Department's season tables; a reservoir not read on a day repeats its last reading there.
