Does anyone know the time scale on these please? I've wanted to paddle them for a long time - any idea how long I have left for both please?

Thanks

As far as I know Isimba dam on the Nile started construction in 2013 and 'should' be complete in 2017 (delays are common in dam construction). I've seen quite a bit of campaigning for the lower dam height option, but as the construction company is Chinese and the loan extension is from a Chinese bank it does not look good. Maybe someone based in Uganda has more accurate information (have you tried emailing Kayak the Nile???).

The proposed Batoka Gorge HES on the Zambezi is at a less advanced stage. The World Bank has already approved funding to support ZRA (March 2015) in updating the earlier feasibility studies. I don't think the contracts for the Feasibility Studies and Environmental Impact Assessments have been awarded yet and will take 1-2 years to complete and be approved at best. If you really want an answer you can follow the project...

But I think it safe to say the Batoka dam won't be in place for a few years to come.

The last few times I was out in Zambia they were suggesting 2020 but based on the links posted earlier it doesnt sound like that is the case.

I think the ZRA draft study can be found at the address below, though I haven't read through all of it yet.

Looks like if the dam happens (which hopefully it wont) 2025 seems more realistic or even later. I heard it would flood all the way up to rapid 4, would be a real shame as it's an awesome section of whitewater in an amazing location.

The proposal does not look good for the Day 1 section, most would be lost.

Thanks for that link. Indeed even though it is stated to be a Run-of-the-river scheme (although the dam height is 181m!!) the two design options will inundate a lot of the gorge. Chapters 7 and 8 are where all the bad news is. Chapter 2 provides some status on the project:
"Batoka HES Phase II _layout - Options Assessment Report of March, 2015, prepared by Studio Pietrangeli Consulting Engineers (SP)."

<Quote>
"Dropping the FSL by 20 m (FSL of 740 m) would therefore limit the flooded extent due to the dam to around the bottom of the 5th gorge (based on
low flow conditions in the river), which has environmental and social advantages (such as conserving rapids 1 to 11, which would mean a half-day
rafting trip is still a possibility, and less habitat loss in the gorge)." (FSL - Full Supply Level - Above mean sea level) - Chapter 7

"The proposed Batoka HES, depending on the FSL chosen (762 m versus 740 m) will result in the total flooding of rapids, either up to Silent Pool (762 m scenario) or up to the bottom of 5th gorge (740 m scenario). The latter scenario will result in rapids 1 to 11 being preserved."
Chapter 8.

It is worth realising that the purpose of an Environmental and Social Impact Assessment is not to determine whether to go ahead or not. At worst it is about placating donors such as the World Bank and at best about mitigating, avoiding or compensating for impacts when it does go ahead.

The 'good' news is that the assessment of the Kariba dam plunge pool is complete with very bad news regarding its stability. So ZRA may have other priorities right now. https://www.newsday.co.zw/2014/03/20/ka ... -collapse/
