Extract from an Email Exchange following last night's 7:30 Report. It sums up my basic position. I just wish all of those irrigation knockers would get a better understanding of the massive variability of our rivers, the magnitude of the bigger events and the opportunity to have good sustainable economic activity, including irrigation AND good environmental outcomes. We need more storages to conserve a small proportion of water in the big events (actually quite a lot of water), but those storages must be efficient. "Efficient" basically means minimising evaporation (depth) and having the flexibility to allow medium and smaller flows to pass through.
