The reservoir sitting behind Ethiopia's controversial hydroelectric dam on the River Nile has finished filling for the third year in a row, Prime Minister Abiy Ahmed has said.
As the height of the dam wall is built up over the years, the volume of water held behind it increases.
Ethiopia has said in the past that it could take up to another five years to fill up the reservoir of the Grand Ethiopian Renaissance Dam (Gerd), to its maximum flood season capacity of 74 billion cubic metres.
The Gerd has caused controversy with downstream countries Sudan and Egypt.
Egypt, which relies almost entirely on the Nile for its water supply, sees this as an existential issue.
In previous years, both countries have complained that Ethiopia acted unilaterally.
But in a series of tweets Prime Minister Abiy argued that the dam would benefit neighbours - not only in providing electricity, but also reducing flood risks.
Ethiopia sees the dam as a way to bring electricity to millions of its citizens and speed up economic development.
On Thursday, Mr Abiy announced that a second turbine had started producing power.
