Ubangi River
Lake Chad replenishment project

In the 1960s, a plan was proposed to divert waters from the Ubangi to the Chari River. According to the plan, named Transaqua, the water from the Ubangi would revitalize Lake Chad and provide a livelihood in fishing and enhanced agriculture to tens of millions of central Africans and Sahelians. Inter-basin water transfer schemes were proposed in the 1980s and 1990s by Nigerian engineer J. Umolu and the Italian firm Bonifica.

In 1994, the Lake Chad Basin Commission (LCBC) proposed a similar project, and at a March 2008 summit the heads of state of the LCBC member countries committed to the diversion project. In April 2008, the LCBC advertised a request for proposals for a feasibility study.
