Eurobodalla Shire Council, together with its contractor, has begun dredging of the Tuross Head boat ramp area to make it easier for boats to navigate through the channel.
The sand has built up over the last few years but became worse after the January floods.
Up to 200 cubic meters of sand immediately east of the boat ramp will be excavated at the point where the two main channels meet towards the river mouth. An excavator mounted on a barge will move the sand out of the main channel and onto the existing sandbar.
The excavation is expected to take a week, and should finish on the Friday, weather permitting.
The work has been planned around the availability of the specialist machinery and the tides, and will be finished before the Tuross fishing tournament in March.
The boat ramp will remain open during the excavation, except on the morning of 15 February when the equipment is put in place. Access to the channel will be limited while the works take place, especially at low tide, and an exclusion zone will be set up around the excavation site.
