In June of 2022, Sandi was appointed to the California Water Commission by Governor Gavin Newsom. The Commission consists of nine members chosen for their expertise in water issues. They provide a public forum on water, advise the Director of the Department of Water Resources, approve rules and regulations, and distribute public funds for water projects.

Sandi is honored to accept this position and continue her work to protect the waters that California relies on.


Sandi Matsumoto is The Nature Conservancy’s Director of the California Water Program. She leads a multi-disciplinary team focused on securing a sustainable and resilient water future for California.
