On 5 June 2013, a new Intergovernmental Agreement between the Commonwealth and States on Implementing Water Reform in the Murray-Darling Basin came into effect. This Agreement builds on the 2008 Intergovernmental Agreement and supports the objectives of the Murray-Darling Basin Plan, which passed through the Commonwealth Parliament in November 2012.
On 29 May 2015 the Murray-Darling Basin Ministerial Council agreed to amend Schedule 1 (Protocol for consideration of surface water sustainable diversion limit (SDL) adjustment measures) to reflect revised assessment timeframes for the SDL adjustment measures and constraints measures.
On 27 November 2015, the Murray-Darling Basin Ministerial Council agreed to further amendments to Schedule 1. These amendments establish an alternative assessment timeline for a small number of complex and highly prospective supply and constraint measure projects.
