More rain; heaps more rain!

As I said in my previous post, we are getting lots of rain at the moment. We had a huge amount of rain over the weekend, and we have now had 527.8 mm this year so far. If this continues, we should get close to 800 mm this year, and we might go over that.

Regarding inflow, we have had much more than I expected, and that is understating things. According to my calculations, we have now had close to 70,000 megalitres of inflow this year already, which indicates that we should top the 100,000 mark and then some. It should be noted, as ever, that the average inflow into Canberra dams is 180,000 megalitres, which would still mean that we are seeing a deficit. But that could simply be because of the terrible drying of the system that took place over the last 20 years, and we might be building towards a recovery.

So at present my predictions look very shaky indeed.


  1. Alan,

    There will probably be a lot more dancing to come, given the la nina and the change in weather patterns. I am not sure that my long-term prediction will be smashed this year, but my short-term ones already have been. (Which is a good thing - we do not want a water crisis in Canberra.)

    How are things going with you?
