Comments on: Some predictions about when the water might run out http://www.atlantawatershortage.com/20071203/some-predictions-about-when-the-water-might-run-out/ Keeping you informed about the Georgia drought. Thu, 20 Nov 2008 17:10:47 +0000 http://wordpress.org/?v=2.6.3 By: SAK's http://www.atlantawatershortage.com/20071203/some-predictions-about-when-the-water-might-run-out/#comment-2088 SAK's Tue, 18 Dec 2007 21:46:10 +0000 http://www.atlantawatershortage.com/20071203/some-predictions-about-when-the-water-might-run-out/#comment-2088 I'm still a bit perplexed over the water relation to power. In this blog we hear at 1035 ft the bigger turbines stop on Lanier. My question is: What percentage of the Greater ATL Metro does this loss represent? I am on the Allatoona water system. I found a ACE pdf concerning allatoona power generation. First, here's how you find it. Google Drought Summit June 2007. The 1st result is the pdf. See page 4 for the power comment: Allatoona loses 25% of it's hydrolectric capacity at the 828-830 ft level". Hmmm, seems we are at 818 now....so that means we are in a mode of already moving towards power loss of 25% or more already? Please correct me if I'm wrong here. This pdf also shows the SEPA power router mechanism, in fact they make the power quote. THanks to everyone for their helpful info...SK I’m still a bit perplexed over the water relation to power.

In GENERAL the water is returned to the source it came from. That's supposed to always be the plan. The inter-basin transfers are interesting; I'll have to add them to the table above.

I know at least Gwinnett county draws from the lake and returns to the river. There are also some strange inter-basin transfers where water comes out of one system and sewage is returned to a different system. You can see an interesting diagram of that on page 3-5 here - http://www.northgeorgiawater.com/files/WSWC_SECTION3.PDF I'm not really making any "point" with this. Just that you are the numbers guru and it may make a difference in some of the assumptions you make when crunching numbers.

As an aside, much of that water is returned - but it is returned to where it came from - so Lake Lanier for those who withdraw from the lake, and the river for those who withdraw downstream.
