Authorities are looking for a new site for the proposed Tadighoust dam on Oued Ghriss after technical assessments found that the location initially selected for the project was unsuitable.
The dam, planned near Goulmima in Errachidia province, is designed to hold 60 million cubic meters of water and help improve water storage and flood protection in the Guir-Ziz-Ghriss basin.
Further technical and field studies are under way to identify a location that meets construction requirements.
Equipment and Water Minister Nizar Baraka previously confirmed the project during an oral question session in the House of Councillors, saying it was included in the 2022-2027 National Programme for Drinking Water Supply and Irrigation.

Once built, the dam is expected to help replenish groundwater reserves, reduce the risk of flooding and support drinking water supplies in an area repeatedly affected by drought.
The project would add to existing water infrastructure in Errachidia province, including the Gadoussa dam on Oued Guir.
Standing 65 meters high, Gadoussa has a storage capacity of around 224 million cubic meters and supplies irrigation water to an agricultural development covering approximately 5,000 hectares downstream, particularly around Boudnib.
Inside the Kheng Grou Dam construction site, Morocco’s fifth-largest dam, on Thursday, October 15, 2026. Construction is 91% complete.
Work is also nearing completion on the Kheng Grou dam in neighboring Figuig province.
Construction of the MAD 1.2 billion project had reached around 91% in October 2026, with the dam expected to enter service by the end of December.
With a planned capacity of approximately 1.07 billion cubic meters, Kheng Grou will rank as Morocco’s fifth-largest dam.
The reservoir is expected to improve drinking water security, support irrigation and reduce reliance on groundwater in the Guir-Ziz-Ghriss basin.
Although the dam is scheduled to enter service in December, the remaining construction work is not expected to be completed until March 2027.
