Ok, I got the lowdown today on what all of this is about
They are fracking where the swimming pool is/was, pressurizing it, and piping well water to the new hatchery building. So it's "fracking" with compressed air....but for spring water instead of natural gas.
Allegedly this is being done separate from the aquifer that feeds the spring.
A similar thing was done at the Callaway nuclear power plant to cool the rods, if I remember right.
