While catchments in the Far East are extensively forested, there have been problems in the past with bank erosion along sections of the river and with sediment (sand) travelling downstream and threatening the ecology of significant wetlands, including Mallacoota Inlet.
These problems resulted from a combination of human actions (land management, road construction) and natural events (fires and floods).

A report in 1992 concluded that future management activities to control erosion and sedimentation should focus on the rehabilitation of the main channel erosion sites, and immobilise sand through revegetation of stream verges. To do this along the entire Genoa River, interstate cooperation between river management authorities in Victoria and New South Wales was needed.
In the following years, the East Gippsland CMA and its predecessor (the East Gippsland River Management Board) completed rehabilitation works that significantly reduced erosion on the priority sites identified in the report. The works included bank stabilisation, fencing and revegetation, reduced stock access to waterways, and interstate programmes to control pest plants, with a focus on willow eradication.
These works were very successful and it is often difficult to recognise the rehabilitated sites today when comparing them with past photographs of the same sections of rivers. Some examples of these works are shown in the ‘before’ and ‘after’ photographs here.
Current works on the Genoa River typically involve the maintenance of fencing particularly after flood events, weed control including willows, and some plantings to support natural revegetation along the banks of the river.
