Is TVA minimizing the truth again?

First, I want to openly thank the EPA On Site (or Scene) Coordinator (OSC) Leo Francendese and his team, for making significant data available on the Kingston TVA Plant fly ash release. (link...)
This past week, TVA was scheduled to release the bathymetry of Emory from before and after the May 4th "flood" event. What they did was to say that a "few feet" of sediment was deposited in the mouth of the Emory River where it empties into the Clinch. To me, a "few feet" means four plus or minus.
From the maps on the EPA OSC's site, (link...) and (link...) it appears that at the centerline of Emory's mouth, the post flood bathymetry shows the elevation of the riverbed of is about 725-730, and of the centerline of the pre spill channel is about 740. That's shallow, since the elevation of the surface is normally only about 741 feet. The pre flood bathymetry at the centerline of the river is about 700, or about 40 feet deeper that after the "Flood". That is much more than a "few" feet in my book.
Again, many thanks to EPA OSC Leo Francendese and his team for posting the maps. I won't even go into the "Gain and Loss" map where the area of the greatest ash (sorry, I mean "sediment") gain was grayed out.
Respectfully,
Charlie Smith

Maybe it's time to remove all the bad stuff from the Emory Clinch confluence.
Before doing this, I would want to build a screen over the hazardous stuff.
I would need some way to immobilize the top of the ash under water.
Before I did that, I would drive a suction pipe to the bottom of the stuff.
I would also put out an array of short pipes with plugs in the top of the ash.
Then use whatever to immobilize the top of the ash underwater.
Then start to suck the stuff from the bottom, opening the plugs in a way to control the flow of river water down into the stuff.

…funny how the "Gain and loss" doesn't highlight the shallows at the mouth of the Emory, or at the "low dam" in the Clinch. Looks like summer's cool bottom waters from the Clinch will be flowing downstream, not up the Emory to KIF. Expect TVA to want to dredge right away.

If Kingston had ash in their water intake, what was going on at the Rockwood water intake that really is downstream?
Just curious.
