DISCUSSION 



Question: What are the implications 

 for water release in the Woodruff 

 Dam? 



Answer : The Woodruff Dam is actually 

 a flow-through system. They don't 

 have a storage capacity. During the 

 winter time it flows at the normal 

 actual river flow. In fact, we 

 modeled the river before and after 

 and there is no difference in flow. 

 The only difference has to do with 

 the freshwater fishing along the 

 river. During the low summer flows, 

 I can tell you when everybody is 

 turning their air conditioners on, 

 because you've got big six-foot waves 

 going down the river which are 

 destroying the habitat of freshwater 

 fishes which are trying to reproduce 

 at that time. I would say that the 

 only control would be relatively 

 minor and possibly not even allowed 

 because they have a certain legal 

 amount of water that has to go over 

 that dam. The only way they could 

 help the situation is in the summer 

 flows by not running it in at times 

 when the freshwater fishes are try- 

 ing to reproduce. 



Question: 



There's not a hydro- 



electric generator, is there? 



Answer : Yes, there is. 



Question : The only release of water 

 that takes place in the summer is 

 through the hydroelectric reserve? 



Answer : We've got other problems 

 that are more pressing than regula- 

 tion, I think. One would be the ac- 

 tual allowance that the river be kept 

 running. It has been projected that 

 by 2005 the Atlanta area will have 

 grown to such a size that we're not 

 going to have any more flow out of 

 the Chatahoochee which is one of the 

 main parts of that system. That 

 would mean that we're all going to be 

 struggling for water. I have heard 

 other papers that are telling the 

 same thing. If there's one thing at 

 this conference that has to be faced, 

 it is that within the next thirty 

 years we might not be getting any 

 more flows that we're showing here. 

 Certainly, these peaks are going to 

 be knocked off that river. There's 

 no doubt that they're going to be 

 able to store enough water there for 

 use, so that you're not going to be 

 getting this peak anymore. This 

 system is going to change. I think 

 we can start to predict how it's 

 going to change by recognizing the 

 relationships we've got right now. 

 As far as controlling the dam, I 

 really don't think that's going to 

 help much at this particular point. 



Question : There's one more point. 



With the effect of the dam do you 



basically have higher lows and lower 

 highs? 



Answer : We've done a hydroelectric 

 record on pre-dam and post-dam flows, 

 and we cannot detect any serious 

 changes in peaking except for minor 

 changes in summer lows and perhaps, 

 somewhat lower highs. 



Answer : Well, it goes through the 

 hydroelectric system, yes, and they 

 are generating electricity. You can 

 watch the peak on weekends. 



Question : So, you've got a general 

 raising of the lows and lowering of 

 the peaks but it's not something 

 real drastic? 



Question : If you could conceive that 

 some kind of water regulation could 

 take place on that river, what would 

 you ask for? 



Answer : The Army Corps of Engineers 

 predicted that the closer they get 

 to the bay with the dams, the more 

 winter peaks will be lowered.
