Mupata Gorge Hydroelectric Scheme

Project Site Location

The proposed Devils Gorge HES is located on the Zambezi River and at the downstream end of the Mupata Gorge which lies between the Kariba and CaboraBassa Dams. The dam site is at Grid Reference ST 991-676 of the 1:50000 scale maps.

Background

The Mupata Gorge Dam site was initially investigated in 1981 by Merz& McLellan, in association with Sir Allexander Gibb and Coopers &Lybrand Associates. This assignment was under British Aid arrangements to carry out a feasibility study with a view to formulate a power development plan for the Government of Zimbabwe.
