FAQ on The Lower River Niger Dredging Project
Attempts have been made to dredge the Lover River Niger in 1958 and in 1978. In 1996, the Federal Military Government approved the dredging project, covering 572 kilometers from Warri in Delta State to Baro in Niger State; and construction of three (3) River Ports in Baro, Idah and Lokoja. Work has commenced at the Lokoja River Port, and efforts are being made to rehabilitate the Onitsha River Prot.
The contracts were awarded to six contractors with the defunct Petroleum Trust Fund as the funding Agency. As a result of the project implementation failure, the contracts were revoked b ythe Federal Executive Council, which directed that the entire project procurement be started all over again. This led to signing of a new contract on December 1st, 2008 involving five supervising consultants in addition to the four contractors.
The contract is currently at the implementation stage with advance payments made. In the next few pages, we have tried to answer questions that are frequently asked by the general public in respect of the dredging of the Lower River Niger.
The details of this project can be found in the links below:

13. What are the basic socio-economic benefits of the dredging of the Lower River Niger?
- It will create employment in the affected Communities.
- It will promote both public/private commercial activities.
- It will generate and sustain industrial development within the inland waterways maritime sub-sector.
- It will provide jobs for the restive youths, especially in the Niger Delta and reduce militancy.
- It will promote tourism and enhance intermodal transport system.
14. What do we mean by Capital Dredging?
Dredging to effect a major change in shape and size in the river bed and navigable channel, normally a recurrent (yearly) exercise.
15. What do we mean by river training works?
They are additional works, of civil nature that are executed concurrently with the Capital and Maintenance Dredging works to give the river hydraulic efficiency, i.e. installing marine structures levees, groynes, bottom panels, dykes to make the river self flushing (or dredging0 and stabilize its banks against erosion and degradation.
16. What do we mean by Maintenance Dredging?
Dredging to retain the geometric features of the river bed and navigable channel, normally a recurrent (yearly) exercise
17. What do we mean by de-rocking?
Breaking and removal of surface and submerged rock formations from the navigable channel.
18. What is the hydrographic survey?
It is survey work carried out in the marine environment to determine sea, lake and river-bed levels in relation to water surface levels at a particular time. Such surveys/measurement are always tied to permanent land-based marks or beacons called reference monuments.
19. What do we mean by navigational aids?
Navigational aids are objects designed and placed in the river to delineate navigable from non-navigable areas in the river. They are also used to mark immovable hazard within the navigable waterways.
20. Why do we need inland ports complement the dredging project?
We need inland ports because the river users would require intermediate stations to load and off-load persons/cargoes. The local riverine population also requires points of interface with voyagers for trading/transfer of goods to link more inland communities. These inland ports or transshipment points are therefore major position of interface between the shipping companies and the general public.
21. Is it true that the dredging will make fishing in the rivers difficult?
Constraints to fishing activities shall be of a temporary nature. Rather, increase in the depth to be achieved at the end of the dredging exercise is expected to initiate the migration of bigger fishes into the navigable channel from shallower adjoining tributaries and water bodies.
22. When will the dredging proper start?
Sometime in November 2009
23. How long will it take to complete the dredging project?
3 years for both the capital and maintenance dredging exercises
24. How will the dredging project be funded?
By the Federal Government of Nigeria
25. What do we mean by E.I.A as it affect the dredging project?
Environmental Impact Assessment: This assessment of the project is expected to highlight its positive and negative effects on the environment of boundary riverine communities.
26. What is the environmental impact mitigation?
Measures provided to cushion the effect of environmental degradation in life.
27. What will be the depth and width of the Lower River after the dredging exercise?Navigation channel shall be dredged to achieve a trapezoidal configuration;
Depth below chart datum - 2.5m
Bottom Width – 60.0m
Top Width at line CD – 100.0m
28. What is dredging Chart Datum (CD)?
Dredging Chart Datum is a measurement benchmark of the waterline established during pre-project execution period (low waters) between the months of February and March.
29. What is permissible limit?
Limit of sweeping river bed or channel.
30. What is dump Spoil?
Site used for sand dump in the course of dredging.

No, only inland waterways crafts and barges will be able to navigate the River Niger
33. What will happen to waterways if after the dredging it is not utilized?
It will become a colossal waste of public funds. Lack of attention and interest may result in the gradual filling out of the river to status quo.
34. What mitigation measures have been put in place against negative impact of the project?
(a) Supply of potable water; (b) Construction of buildings and utilities for riverine communities; (c) reclamation of shore fronts; (d) construction of access roads.
