A notice to mariners was posted in early March on the Marine and Safety Tasmania website, alerting mariners that dredging operations would take place on the Tamar River's eastern side.
The notice says dredging will occur between March 9-25 near Kings Wharf.
It's understood the dredging is being undertaken by Southern Marine Shiplift, which has a historic agreement for the dredging.
Pipes set up for the dredging show that the sediment being moved from the Kings Wharf area is being pumped to another part of the estuary, which Mr Stewart said wasn't helping with build-up.

However, Mr Stewart, a founding member of the Tamar Action Group, said moving sediment around from one part of the estuary to another would not help solve the solution of mud build-up.
The sediment build-up is causing angst among the business and recreational boating communities and other river users.
"We have all agreed that raking was not the way to go, because of the disruption to the water quality, but if we are going to dredge we need to take it out of the river," Mr Stewart said.
"Companies [like Southern Marine Shiplift] have to do what they need to do, it's not their fault at all, but we need to be having the conversation that if we're doing to dredge, we should be strategic."
Mr Stewart said while he hadn't seen an immediate impact, dredging operations like the one underway at the moment would eventually impact his marina at the Seaport.

"It's likely going to make its way to outside the Silos or at the marina."
The water flow around the Silo Hotel has clogged up with so much mud it's "more like a stream than a river", Mr Stewart said.
Part of the solution would be to dredge but remove sediment, not push it around to other places, Mr Stewart said.
"It's not the only solution, but it's part of the solution. But we need TEMT to release the report public as soon as possible to ensure we know all the options on the table.
A TEMT spokesman said the sediment report was not yet complete.
"It is expected to be presented to the TEMT next month," they said.
