Climate change or our utilities being owned by corporations?

Apparently they have minimal flow from the aquifer at the moment. They are testing the fish tolerance the to minerals in the water. If they are okay, more hot water can be accessed through other aquifers, with the intention to return the temp close to what it was originally. This all depends on how the Barra's cope with the water quality from the aquifer/s.
Is this being done by fisheries and the station operator engine?
It's Fisheries who are doing the work. They've been using Charlie Carp to catch the Barra using electro-fishing, relocating the caught fish into the heated channel to monitor the impact of the aquifer water quality.
Interesting why not just pump it through and see what happens.

t's good to see they are working on a solution to keep the fishery going.
Hopefully it works out if theres no other alternatives why not pump away and hope for the best though.

The aquifer they are using doesn't output enough water to heat the lake. They need to access others as well. I'd reckon the cost of connecting additional aquifers would be a major factor, especially if they are unsure if it will work.

Wonder where poacher Paul and no early fish Kramer are now with all this or has the gold rush finished.
