There is currently a surplus of water in the Orange River basin even after the
influences of Phase 1 of the LHWP have been taken into account. It is
therefore likely that some further developments will take place to enable the
surplus to be utilised, either inside the Orange River basin or through
additional transfers to the Vaal River basin. Transfers to the Vaal River
basin can take place either through the second phase of the LHWP or via a
transfer situated wholely in South Africa - (ie. the Bosberg Dam which is
located upstream of Gariep Dam).
Numerous possible future developments along the Orange River have been
considered as part of the Orange River Replanning Study (ORRS). To date,
no firm decision has been taken regarding which developments, if any, will
proceed. Of the 30 or more possible dams considered along the Orange
River, most have been eliminated from further consideration due to either cost
or environmental/social implications. Of the remaining developments under
consideration the following are the most promising (in no particular order) :

No decision has been taken with regard to any future development and various new
studies will be undertaken to evaluate the various possibilities.
