A look at the possible size of the Reservoir created by the proposed Dasin Hausa Dam using a topo map.

Some interesting observations.
The possible resulting lake could have a surface area of ~1,950km2 & volume of ~15,000 Million m³.

The Cameroonian city of Garoua would be greatly impacted by the resulting lake. Also the towns of Barndaké & Pitoa would be fully submerged and residents would need to be relocated.

The Dam would capture overflow from the Lagdo reservoir and the water from the Faro river, but the other major tributaries of the Benue river are still left open.

in regards to the impact the Dasin Hausa Dam would have in flood prevention downstream of the Benue and Lower Niger, it would definitely not be sufficient.

The recent imagery from October 11 2022 showing the expanse of the rivers vs the October 24 2021 image illustrates this.

A Dasin Hausa Dam would be able to hold some water from the northern portions of the Benue, but it would not be able to capture water from other tributaries downstream.

The 2022 Nigerian floods is devastating, but Nigeria would need more than the Dasin Hausa dam to prevent future damage and displacement.

The before and after image of the Niger river between the town of Agenebode in Edo state and Idah in Kogi state shows a river massively overflowing its banks submerging some homes in both towns.

For those still intent on blaming Cameroon for the floods, here's what the Nigerian Minister of Water Resources, Mr. Suleiman Adamu had to say.

You heard that right. The Lagdo dam's contribution to the flood waters in Nigeria is only 1%.

Heavy Rains feeding into the Niger & Benue rivers are the main cause, so Nigeria has to take a more comprehensive look at how to mitigate negative impacts of the floods in the future.
