According to the former Sokoto Rima River Development Agency (SRRDA), Mukhtar Ahmed Anka, the reservoir was constructed for the provision of portable water for Shagari council and its environs and to improve the social and economic well-being of residents in communities around the dam.

But 15 years after construction, the intended social and economic benefits are yet to be achieved.

The Shagari Earth project involving a dam construction which began in 2004 and was completed in 2007, and an irrigation scheme, yet to commence, remain moot over a decade after initiation.

The project is supposed to be functional upon the completion of the irrigation scheme, but 15 years after the completion of the dam, the scheme is yet to take off.

The Irrigation scheme was initiated to provide irrigation fields, and drainage, and facilitate the cultivation of crops by the farming communities in its vicinity during the dry season.

WikkiTimes learned that, in 2009, the project was awarded to Messrs C.G.C. Nig. Ltd. for the sum of N847, 238, 749.88. Project Description

The main features of the Project include:

Earthfill dam with reservoir capacity of 15 Million cubic metres (MCM); 13 m high, 1,340 m long. Quantity of earth material, V = 320 000 m3. Associated concrete works (Bottom Outlet, Spillway, Intake Tower) for a total volume of 5 241 m3. Homogeneous shell fill with central clay core and filter placed on a 1.5m thickness of clay blanket. Because of the excessive depth of the impervious layer (24 – 28m), clay blanket of thickness 1.5m with an extension of between 30 – 50m into the reservoir was constructed to control the rate of seepage flow underneath the dam body. Development of 1,000 Hectare of irrigation scheme.

Our role on the Project included Detail Design, Preparation of Construction drawings, Work Programming, Monthly Work Valuation and general direction of the works.
