. The CDC was managing agent for the project, and the construction contract was awarded to NECCO, a company largely owned by the government.
The Savannah Sugar Company was acquired by Dangote Industries
in 2002. In 2009 the company owned 32,000 hectares of land near the dam or which 6,330 were in use and employed about 5,000 people.
The company was producing about 50,000 tons of sugar annually, supplying the Nigerian market which consumes 1.1 millions tons each year.
Over 1,000 hectares of irrigated rice and other crops were being grown using the company’s canals.
The dam has affected the lower reaches of the Gongola River. Flood peaks dropped from 1,420 m³/second to 1,256 m³/second, while flows in dryer seasons increased from 5.7 m³/second to 21 m³/second.
The river downstream from the dam has narrowed and become less winding, with fewer separate channels.
In October 2008 the United States Trade and Development Agency issued a request for proposals on constructing a 35 MW hydro-electric power plant at the dam.

The company was producing about 50,000 tons of sugar annually, supplying the Nigerian market which consumes 1.1 millions tons each year.
Over 1,000 hectares of irrigated rice and other crops were being grown using the company’s canals.
Impact
29,000 hectares of land were expropriated without compensation, eventually displacing 20,000 people. Resettlement assistance was inadequate.The dam has affected the lower reaches of the Gongola River. Flood peaks dropped from 1,420 m³/second to 1,256 m³/second, while flows in dryer seasons increased from 5.7 m³/second to 21 m³/second.
The river downstream from the dam has narrowed and become less winding, with fewer separate channels.
Future
An assessment of the dam in 2004 rated its condition "good".In October 2008 the United States Trade and Development Agency issued a request for proposals on constructing a 35 MW hydro-electric power plant at the dam.
