Out playing today and took some shots.http://i826.photobucket.com/albums/z...psooyonopt.jpghttp://i826.photobucket.com/albums/z...psvhtqq5n5.jpghttp://i826.photobucket.com/albums/z...psnswjbaeu.jpghttp://i826.photobucket.com/albums/z...pssmhse5of.jpghttp://i826.photobucket.com/albums/z...psopmmuux8.jpghttp://i826.photobucket.com/albums/z...psgitg5znl.jpg
Ok,what is that
Were you getting an incorrect depth reading off the top of the coffer dam cells...??
(On the lake side of Ky Dam, Brett....left from construction of the dam in 1938-1944)...
The 80' reading in the last shot seems more correct for where those actually are...
Rickie
I wonder what the "zigzagg" lines against the bottom detail are in the 800kHz shot ...??
They don't show in the 455kHz shots...
:dono
Rickie
What is a dam coffers anyway.
It looks like you ran right over it.
I did have a picture of the coffer ,that was taken during its construction but I can't find it.Quote:

Rickie,its possible that it could be a dept glitch,I didn't really pay attention to the dept reading.
If I remember correctly while on the top of the coffer cells the water gets into the 30ies and off the sides into the eighties and the deepest water is closer over towards the intakes,its a little over 100ft.right now.(theres some kool looking things over there that look like tombstones standings up)
Im not sure either rickie,thats the first time that I have went out to 300+ range. Im guessing that it could be the pulse modulator on my trolling motor.i have all filters, currently turned off.ill experiment some to see if anything changesQuote:

Brett when I first saw those from some of his earlier shots I had the same Q lol
Those are awesome pics of the coffer dam :ThumbsUp
Brett and coffer dam is made of interlocking panels that are hammed into the ground one sheet at a time. Once the dam is built the water can be pumped out so the building can began. Most of the time these panels are removed after the building is complete but some just can't be pulled out. I have seen times when they send a diver down to cut the panel off, this may be the reason those in the pics are still there or they were low enough after the lake filled to not be any danger and it was cheaper to just leave them in place.
I read an old copy of a book written about the Ky Dam Project...(I don't even remember the name of the book)...Quote:

The book also read that the dam was built in 3 stages....
1. Lock and powerhouse
2. Gates 1-14
3. Gates 15-24
The Tennesse River had to be "redirected" before each of the 3 stages of construction...
I'm not sure which of the 3 construction "stages" these coffer dam cells are left from...
Hey kosmo....which gates are these coffer dam cells in front of...??
Rickie
Rickie,if your facing the dam,these are the ones at the west end.i guess that gate 1 would be nearest to the turbines.that would make these 15 - 24
I guess that would make sense then...the coffer dams around 15-24 would have encompassed the last last stage of construction ...and they just left them there ...(probably to save money on the project ...beings as they were not navigational hazards)...Quote:

kosmo...do you have a shot of the very last coffer cell to the East of that line of cells... to see how many cells were removed from the last east cell to where the line of cells would have attached to gate 14...??
Rickie
Rickie,heres a trivia question for you.name the person that was responsible for having the dam built in its location ?(theres a local town named after him)
I do not know....Quote:

Here's a pic of the coffer cells being attached to gate 14...(I think)...

Rickie, I'm pretty sure that's the down river side of the dam.
I agree ...from the way the concrete vertical wall looks...Quote:

BTW...the pic did not indicate for sure that this was gate 14...I'm just guessing from the layout of the items in the pic...
Rickie
In the 1940s, the construction of nearby Kentucky Dam by the Tennessee Valley Authority brought plentiful electric power that led to many industrial plants, mostly chemical manufacturers, to locate between the city and the Tennessee River. Merchant Luther Draffen was instrumental in attracting the dam and industrial plants. (I agree ith justin,the picture you doesn't look to be part of the coffer
http://en.m.wikipedia.org/wiki/Calve...ntucky#History
Click on the kentucky dam link.theres some good pictures there
That's interesting...I knew he was the namesake if Draffenville but I did not know he was involved in attracting the dam being built where it is now located....Quote:

RIP Ruben.
I vaguely remember from the book (...The Kentucky Project...I think was the name)...that the coffer cells were attached to gate 14 at both the downstream (North) side of gate 14 and the upstream (South) side of gate 14...and then completely encompassing the "Stage 3" construction area...
Then the Tennesse River could have been allowed to flow thru gates 1-13...while leaving the "Stage 3" construction of 15-24 dry in the "Stage 3" coffer cell encirclement...
I'll have to see if I can borrow that book again from its owner..(he refused to sell me that book...for any price)...
Rickie
Rickie,I believe that this could be the coffer dam for 15-24 gates.what do you think?http://i826.photobucket.com/albums/z...psrdc2q7lv.jpg
The scale of this dam is something I was not ready for
those are huge!
With the river (in the foreground) being on this side (west) of the gates 1-14 showing...and Gates 15-24 concrete not started yet....I would guess this photo would have been during construction of the "Stage 2" gates 1-14....(indicated by all the cranes still affixed atop gates 1-14)...Quote:

The things I read in that old book I borrowed would make an OSHA person have nightmares...Quote:

Rickie did you notice in the link you provided that in the photo of "downtown Gilbertsville" the signs on one of the buildings advertised Falstaff beer.
I had not noticed that Falstaff beer sign before...Quote:

I actually have my Dad's copies of most of these photos from when he worked for TVA....(he was interested in this history because he was born at Gobbler's Knob above the Ky Dam Marina bay)...
He told me stories of how he and his siblings walked across the "peanut patch" in the Taylor Creek bottom to get to the old Gilbertsville grade school...(this "peanut patch" is now the bay where Ky Dam Marina resides)...
Rickie
Here's a couple photos of the pre-Ky Dam site from the air....
This is the proposed dam site from the South looking North...(you can see the tip of "27 mile island" in the lower right)...

This is the proposed dam site from the North looking South...(you can see the entire "27 mile island" in the center...starting just past the railroad trestle)....

For those who have access to a Ky Lake paper map or the Navionics East region card..."27 mile island" can still be seen in the lake bottom topography of KY Lake just to the south of the turbines and the first several gates...
This is the same "27 mile island" in the photos above...
Rickie
In the top image looking north just down river from the left bend was my Grandfathers place, he was probably following an old mule around somewhere there when the photo was taken.
JUSTIN,IS IT NOT FUNNY ,BACK THEN WE CALL A MULE A DUMN ANIMAL AND YET WE FOLLOWED THEM:Rofl
When I was a kid there was a bunch of horse drawn equipment sitting around on his farm, even until I was in my 20's. I could've got any or all of it, proves how smart I'm not. The river bottoms on that farm were over 1 mile long and close to a 1/2 mile at their widest part. I can't imagine walking that behind a mule, but he did. We farmed it and it seemed it took forever to get from one end to the other on a tractor. When my Grandfather was in his 70 he could still work most men in the ground. Early to bed and early to rise.
I get nervous in my boat near the dam.
Not sure why
Is this area water?
I don't think it's water ricky...Quote:

From Google Earth...it almost looks to be about where Jim Smith Construction is ...and it doesn't look like that area is far enough away from the river to be the startings of (Clyde) Reed's Crushed Stone...

Ok that bridge is the one that went below where the dam is now? duh
Very cool stuff. Keep it coming.
It is my understanding that the concrete pillars that presently show in the river (below the dam)..at low river water levels ...are the concrete platforms that held the old railroad trestle seen in this pic...Quote:

That would put the dam construction just this side of the railroad trestle in the above pic...and constructing the dam right across the tip of "27 mile island" that shows in the lower right if the above pic...
I vaguely remember from the book that the narrow channel around "27 mile island" (also seen in the lower right of the above pic)...was widened to allow for diversion of the Tessesse River to begin "Stage 1" construction of the Lock and Powerhouse...
