Griffith's Glen Andreazza will be stepping up as the new chairman.

Cr Maytom has been chair of region nine for over a decade, and has been a member of the MDA for over 25 years.

While he'll be stepping down as chairman, he will remain involved as a key member of the executive committee.

MDA's chief executive officer Emma Bradbury had kind words to say after Cr Maytom's long tenure.

"Paul's considered wisdom and passion for water and community has brought much balance and reason to the journey of water reform in the wake of the Basin Plan," Ms Bradbury said.

"On a personal note, Paul's leadership, quiet counsel and formidable commitment to the MDA has been and continues to be an inspiration to me."

Incoming chair Cr Glen Andreazza said he was happy to take the role in order to keep it in the central irrigation areas.

"I'm quietly excited," he said.

"Paul Maytom decided he wanted to stand down and on that, he needs to be applauded for everything he's done.

"We need to keep this sort of thing in Griffith, being an irrigation area. Griffith and Leeton are the heart of the irrigation, so I was happy to put my hand up."

Cr Maytom said the MDA would be in good hands.

"I am confident that his strong leadership will ensure local government and communities continue to work together to achieve a healthy, vibrant and thriving Murray-Darling Basin," he said in a statement.

Cr Andreazza has big plans going forward for the region and the Murray-Darling itself, after joining the group in 2019.

"I went to the conference in Toowoomba that year and that's where I was introduced to the MDA ... the Yanco Creek Sustainable Diversion Limit's back on the agenda," he said.

"There's works and measures that are supposed to be there and they haven't been done.

"Rather than getting new water, it's just being smarter with the water we've got. They're not going to build more dams, so we need to be more efficient with the water that we've got."
