Seasonal determinations increase slightly in most systems

By Rodney Woods

Seasonal determinations in the Murray, Goulburn, Loddon and Campaspe systems have all slightly increased in the latest seasonal determinations, released on March 2.

In the Murray system, seasonal determinations increased from 57 per cent of high-reliability water shares to 59 per cent HRWS, while the Goulburn and Loddon systems increased from 71 per cent HRWS to 73 per cent HRWS.

The Campaspe system moved from 71 per cent HRWS during the middle of February to 72 per cent HRWS now.

However, users of the Broken system were not so lucky as they continue to sit on a seasonal determination of zero per cent HRWS, while the Bullarook system also remained stagnant on 100 per cent HRWS and 100 per cent of low-reliability water shares.

The positive news is the shortfall in the Broken system reduced during the past fortnight, but there still remains about 800 Ml to gain before a positive seasonal determination can be made.

Northern Victoria resource manager Mark Bailey said continued milder conditions and some rainfall in the past fortnight had contributed to water availability improvements in some northern Victorian systems.

“The rainfall slightly increased flows into the major storages in the past fortnight and meant evaporation losses were lower than our conservative estimates,” Dr Bailey said.

“This enabled the small increases in the Murray, Goulburn, Loddon and Campaspe systems announced today (March 2).”
