Previous water years
Data from the most recent water years is now available for the Snowy River and Snowy Montane Rivers. Significant high-flow events were recorded along with some associated rising river alerts.
2015–2016
A total of 148,384 megalitres (ML) was available for release in 2015–16. This included an allocation of 139,384 ML from Snowy River Increased Flows (SRIF) plus a base passing flow of 9GL, with 5GL and 8.5GL from delivered from the Mowamba Weir and Jindabyne Dam respectively.
The SRIF strategy also included higher flows over winter and spring, with five high flow events occurring in winter/spring 2015.
Additional to the hydro-scaling approach another trial release of water from the Mowamba River to the Snowy River occurred during May 2015.

2014–2015
A total of 155.3 gigalitres (GL) was released in 2014–15. This included an allocation of 146.3 GL from Snowy River Increased Flows (SRIF) plus a base passing flow of 9GL, with 0.5 and 8.5 GL from delivered from the Mowamba Weir and Jindabyne Dam respectively.
A complementary tributary release from the Mowamba River to the Snowy River occurred in May 2014. This trial was linked with scientific experiments to assess the value of unregulated tributary releases in delivering Dissolved Organic Carbon and its influence on the aquatic food-chain.

2013–2014
Prior to 2013, the capabilities of the new outlet infrastructure at Jindabyne Dam had not been fully utilised to provide environmental flows to the Snowy River below Jindabyne. The annual target for releases from Jindabyne has steadily risen from 38GL in 2002–03 to 181.6 GL in 2013–14.
During 2013–14 a total of 190.6 GL was released to the Snowy River below Jindabyne, with 96.6 GL allocated to the spring 2013 releases. The release strategy also included five spring flood events.

A handful of high-flow release events from 2013 were captured on camera from three key sites; Jindabyne Gorge, Dalgety Uplands and Burnt Hut Gorge.
