The Wallamba River in the Wallis Lake Catchment near Tuncurry is exposed to severe bank erosion due to past vegetation clearance, ongoing cattle grazing and wash from boats. Bank protection and restoration works along 200 m of the Wallamba river bank was undertaken and involved the installation of 10 rock fillets, linking existing bank stabilisation works upstream and downstream of the site. Collectively, 4 km of consecutive river bank has been stabilised. Completed in 2012.
