The Leschenault Catchment Council, in partnership with Clean Up Australia, is calling upon community members to help out an area significant to the region.
Volunteers will be working tirelessly during Leschenault Estuary Foreshore Clean Up Day on Sunday, March 17.
Around 60-70 community members are expected to pick up rubbish along the foreshore.
Volunteers will meet at the reserve opposite Christina Street at 9am, before walking along the shoreline.
Leschenault Catchment Council manager Chris Howe said the campaign was essential for keeping the estuary clean.
"We'll organise where the volunteers will go and we'll try to target as much of the foreshore as we can," he said.
"Ideally, we would like to go from the Collie River to as far up the north end as possible."
Mr Howe said the council and community were dedicated to protecting the local waterways.
"There's already a small group of about 10 volunteers who clean up the foreshore regularly," he said.
"Rubbish causes a great deal of damage to our environment.
"The clean up day is important for the awareness that it raises...it's an eye-opener. Hopefully, it will help people to teach their kids not to litter."

Volunteers are encouraged to wear long sleeves and enclosed shoes.
