Dunmunkle Creek will receive fencing, revegetation and animal control after plans to improve the waterway's health were finalised by Wimmera Catchment Management Authority.
WCMA operational delivery manager Luke Austin said the plan aimed to improve the creek's health, protect remnant vegetation and improve connections between vegetation.
The waterway action plan has been developed over the past six months through community meetings and site inspections.
Mr Austin said the community input had been valuable in finalising the plan.
"We would like to thank the community for their contribution and we look forward to working together to improve the Dunmunkle Creek," he said.
Dunmunkle Creek is a distributary of the Wimmera River, getting its natural flows through a breakout from the Wimmera River north-west of Glenorchy during times of high flow.
The creek flows through Rupanyup and continues north into the southern Mallee.
The action plan covers an area from the Wimmera River near Glenorchy to Lawler Road, Boolite.
Mr Austin said weed control was important, with the highly invasive and noxious horehound and boxthorn weed prevalent throughout the river zone.
Other objectives outlined in the plan were to improve flow connectivity to enable environmental watering, protect drought refuges for plants and animals and maintain social, cultural and economic values.
The waterway action plan will be part of the CMA's annual works program, with a date still to be set for the plan to start.
