Rain & Dams

Timely to update some weather:

Rainfall 0920

This is Cairns Aero where the annual rainfall has now nudged down to the lowest total since January 2013 following a weak wet season. Latest update from the BOM is that the current seasonal outlook is looking wetter due to a higher La Nina probability and the Indian Ocean Dipole: Weekly Tropical Climate Note

Rainfall can play out differently within the region as shown in a comparison of dam levels at Copperlode which supplies Cairns water and Tinaroo which supplies irrigation water to the Tableland:

With an imminent election the Bradfield scheme to divert coastal rain inland has been revived to tri-partisan support: Experts to examine new Bradfield scheme proposal

Which is interesting because the graphic appears to include a diversion south from the North Johnstone which has previously been flagged as a preferred option to boost supply at Tinaroo.

I previously looked at the comparison between the Burdekin and Tinaroo here two years ago: Dam Divergence
