Snowy Hydro's cloud seeding program in the NSW Snowy Mountains operates under the Snowy Mountains Cloud Seeding Act 2004 and requires five-yearly Environmental Management Plan (EMP) reviews. The program has increased snowfall by 14% on average during suitable conditions and generates water for hydroelectricity and Murray-Darling Basin irrigation. Snowy Hydro paused 2024 operations due to unsuitable weather conditions (low cold front frequency and warm temperatures), not program effectiveness. An updated EMP was approved by relevant NSW Ministers in July 2023 following EPA-coordinated stakeholder consultation. Annual reporting requirements mandate compliance documentation and environmental monitoring data on tracing and seeding agents. Commercially sensitive operational details were withheld from disclosure.
