- The dam stands in the commune of Oudka on the Oued Oulaya, a main tributary of the Oued Ourgha in the Sebou basin, and will be the second largest in Morocco after Al Wahda.
- Storage exceeds one billion cubic metres, height approaches 100 metres, the rockfill embankment runs to more than 22 million cubic metres and the concrete face will cover 26 hectares.
- Overall cost is estimated at 4.5 billion dirhams including studies, works, supervision and expropriation.
- Works were launched in March 2022 and stood at 38 per cent.
- The provisional diversion of the Oued Oulaya was completed at the end of September 2024, about 6 million cubic metres of fill had been placed, the spillway was 90 per cent complete and the access road 80 per cent.
- Impoundment is set for the end of 2028, more than a year ahead of the original date.
- The project chief is Mohssine Bahtat and technical control is by the Laboratoire public d'essais et d'etudes.

Progress reached about 53 per cent, after about 30 per cent in mid-2025 and more than 42 per cent in September 2025, and the project includes a hydroelectric plant. The two reports disagree on mid-2025 progress, Le360 giving 38 per cent in June 2025 against about 30 per cent in Fes News. Budget converted from 4.5 billion dirhams at about ten dirhams to the dollar, the rate the register already uses for the Sebou-Bouregreg row.
