Having been to Ghana and to Lake Volta & the Akosombo dam in particular, I'm somewhat torn:
- Yes, it has had a severe impact on the ecosystem, and also on agriculture.
- Yes, Ghana itself only gets about 20% of the power generated by the dam (or apparently a bit more in recent times).
- OTOH, the dam gives Ghana access to at least some power – much more in fact than what's available to any of its neighboring countries. I have heard people say that this is one of the major reasons for Ghana's relative economic & political stability.
