At Ga port, river respirators to help fish breathe

SAVANNAH, Ga. (AP) - Plans to deepen the Savannah harbor include
a costly proposal to
ensure fish can still breathe by using a dozen
machines to inject oxygen into the river.
In its final report on the harbor deepening released this month,
the Army Corps of Engineers
estimates it would cost taxpayers $70
million to get the 20-foot-tall oxygen machines set up,
another $1.2 million each year to maintain and operate them.
The machines would mechanically make up for a small loss of
oxygen at the river bottom
where fish, worms and even bacteria need
it to breathe. The same technology is used in lakes
across the U.S., but critics say using the machines to justify
to the river is going too far.
