>PGM,
I agree with you on the slow release of the
CaCO3. The leaching process that pulls the CaCO3
out of limestone is very slow, and a sudden shift
in the pH of the Hooch could be disasterous. Also,
high pH water or "hard" water will not allow soap
to work, and makes mineral deposits inside of pipes.
For these reasons alone, I'm sure that Atlanta
homemakers, and the City of Atlanta Water Department
would be seriously upset about a change in the
chemical makeup of the Hoochs' water just to please
a few trout fishermen.
The key is the presence of CO2 in the water. This
is basis of the food chain, and the difference between
a good trout stream and a legendary trout stream.
Check these figures out:

Stream CO2 trout non-trout food
(ppm) (lbs/acre) (lbs/acre) (lbs/acre)

Hooch 5-10 10 45 100
Au Sable 20-30 30 270 750
Gunnison 60-90 60 540 3,500

Again, I think the Chattahoochee is a phenomenal
fishery I spend 60+ days a year fishing it, and I
can't wait to get back everytime I leave it.
My concern is people that want to make it into
something that is simply not possible.
It is a put and take trout stream that is managed
for the enjoyment of the general public.
I think it could be a semi-trophy trout stream if
all 15"+ trout were released, but that can't be
regulated.

Enjoy the stockers, appreciate the anticipation of
a possible trophy, and go with the flow.

Hooker
