A selection of prominent and passionate figures in the fight for water will address the crowd at tomorrow's protest rally.

The day will begin with a protest march from Town Square at 11am, which will head to Sturt Park for a public gathering and speeches from invited guests.

At the conclusion of the speeches the crowd will be invited to the Musicians Club to view a video on the plight of the Murray-Darling Basin compiled by Australia Institute researcher Maryanne Slattery.

Mayor Darriea Turley AM said she expected a huge day of activism for the Darling Rivers and Menindee Lakes.

"It's just amazing how this event has come together, we put out a call for people to come and address the people of Broken Hill, and we've had an amazing response," she said.

"The day will be a great opportunity not just to send a message that we demand better treatment for our waterways, but to hear from people who can provide amazing insight into the fight for water.

"We should also make special mention of the Darling River Action Group and Darryn Clifton, who will MC tomorrow's event. They have offered tremendous support.

"We look forward to seeing everyone there in full voice tomorrow."
