Interesting section guys, forgive me if Im about to ask some dopey questions, Im Tasmanian hahaha.

Re the minimum flows, are you guys talking about a 24 average minimum year round or averaging it out with higher minimum for particular parts of the year etc to equate to a more natural river regime? Or a regime which is more beneficial to the trout.
Obviously these are "artificial", if you like, environments anyway.

The O2 issue is over my head.

Reason Im asking is my homeland has totally hydroelectric power system and like most places if facing greater demands on water for irrigation etc and minimum water flow issues are now starting to be looked at for the first time.

Cheers
