New figures

I am probably going to have to change the way I look at rainfall and runoff to a financial year model, as it seems that that is the main way that ACTEWAGL are reporting data.

However, as of this date we have had 270.6 mm of rainfall for the calendar year and - by a revised calculation that removes the 130 megalitres per day of overflow that ACTEWAGL reported for March and April from my May, June and July figures - 33,000 megalitres of inflow. We have had 23,000 megalitres of water usage over that period also, which is sitting at slightly above last year, but - give the uncertainties - is basically the same.
