The Snowy Scheme was designed to cope with large variability in inflows. In the last 110 years of data, inflows have ranged from 683 gigalitres (GL) seen in 2006/07 during the worst drought on record, to 5761GL almost a century ago in 1917. The long term average is just below 2800GL.
The total volume in Snowy Scheme storages is massive and it would take a number of consecutive years of above average inflows to return our total storage volumes, particularly Lake Eucumbene, to above average levels.
We can expect to receive around 50% of our inflows from snowmelt and rain during spring, so a bad snow season can have a significant impact on the total inflows for the year.
2016-17 WATER YEAR
What inflows came in?
Snowy Scheme inflows for 2016–17 were 3,711GL which is about 134% of the long term average of 2,779GL.
In 2016-17 we received above average inflows, resulting in the storages approaching long-term average levels.
