Residents have been invited to have their say on the draft Griffith Main Drain J and Mirrool Creek Floodplain Risk Management Study and Plan.

Council commissioned consultants BMT WBM to review the 2011 Griffith Floodplain Risk Management Study and Plan after the flood.

Graham Gordon, council’s utilities director, said given the March 2012 flood event in Yenda was contributed from Mirrool Creek flood waters overtopping Northern Branch Canal and spilling into the Main Drain J catchment, BMT WMB produced a new flood study Griffith Main Drain J and Mirrool Creek Flood Study which was adopted by council in 2014.

“The flood study defined the flood behaviour of the catchment, both in terms of local catchment runoff and flood flood flow contributions from Mirrool Creek and produced information on flood flows, velocities, levels and extents for a range of flood event magnitudes under existing catchment and floodplain conditions,” Mr Gordon said.

“The outcomes of the Flood Study 2014 established the basis for subsequent flood mitigation measures in which both planning and structural measures that have been presented in this draft report.”

Griffith Mayor John Dal Broi encouraged residents to read the report.

“This is a very important study and it is essential council receives feedback from the community,” Councillor Dal Broi said.

“Two information sessions will be held on Tuesday, June 16, the first at Griffith City Library from 10am to 1pm and the second at the Yenda Diggers Club from 7.30pm.”
