Broken system seasonal determinations increase to 100 per cent of high-reliability water shares

The Resource Manager for northern Victoria today updated the 2024/25 seasonal determinations.

The Broken system seasonal determination increases from 47 per cent of high-reliability water shares (HRWS) to 100 per cent HRWS.

In the Campaspe system, the low-reliability water share (LRWS) seasonal determination increases from 41 per cent LRWS to 44 per cent LRWS. The Campaspe system also has 100 per cent HRWS.

Seasonal determinations in the Murray, Goulburn, Loddon and Bullarook systems are unchanged.  

Resource Manager Mark Bailey said wetter conditions enabled seasonal determinations to increase and carryover rules influenced the large improvement in the Broken system.

“Entitlement holders in the Broken system carried over the equivalent of a 38 per cent seasonal determination of high-reliability water shares into 2024/25,” Dr Bailey said.

“As the maximum volume entitlement holders can receive through new season allocations and carryover is 100 per cent of their high-reliability water shares, the resource improvement needed to reach 100 per cent of high-reliability water shares from the most recent announcement was relatively low.

“This was achieved with inflows into Lake Nillahcootie from recent rainfall and higher flows in the tributaries downstream of the storage.

“The improvements in the Campaspe system came from rainfall in the Lake Eppalock catchment.

“In the Bullarook system, almost all the system operating water has been secured. Additional resource improvements will contribute to seasonal determinations. Customers with carryover allocation are able to access that water when needed.”

The seasonal determinations for northern Victorian water systems on Monday, 2 December are:

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 0%
Broken 100% 0%
Goulburn 100% 0%
Campaspe 100% 44%
Loddon 100% 0%
Bullarook 0% 0%

Trading Opportunities

Allocation trade from New South Wales to Victoria is limited to the lesser of a net annual volume of 200 GL or a volume that keeps the risk of spill in Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent. The current risk of spill in the Murray system allows 200 GL of net trade from New South Wales to Victoria.
