Phillips Landslide, Birregurra (2007/08) At this site near Birregurra, a very large landslide has moved in the past and now directly hangs over the Barwon River and threatens to block the entire river. Various treatments were used at this site in an attempt to drain water away from the landslip and monitor movement of the landslide toe. Both underground and surface drainage techniques were used along with planting out the slopes with native vegetation. [Download Overview Report] (9.9 MB) Erosion on-ground works - Middleton's Site - Meredith – Steiglitz Rd, Meredith, on Deadmans Gully (2007/08) Large scale earthworks were undertaken to rehabilitate a gully and tunnel erosion site near Meredith, on Deadman's Gully. The works involved deep ripping of tunnels and battering of 500m of gully. The whole site was then 'v' ripped which slows surface run-off allowing water to seep evenly into the subsoil. Work to fence out and re-vegetate that site will occur in Autumn 2009. This site was identified as high-risk because of sedimentation to the Moorabool River which is a proclaimed water supply catchment. [Download] (1.6 MB) Erosion on-ground works - Wray's (2007/08) Long-time landholder Lance Wray has completed extensive earthworks on a large erosion gully on his property with the assistance of the Soils and Salinity Incentive Program. The large-scale earthworks battered the seven-metre gully and helped establish vegetation on the 14-hectare site. Lance feels it is important to improve the property's value and environmental sustainability for the next generation. This site was identified as high-risk because of sedimentation to the Moorabool River which is a proclaimed water supply catchment. [Download] (1.7 MB) Wind erosion on-ground works - John's (2007/08) A ridge near Torquay has been subjected to wind erosion, particularly during summer months, which threatens air and water quality and agricultural production. Activities at the site which have addressed the risk include land class fencing, which will allow better grazing management practices to maintain groundcover. [Download] (111 KB) Gully erosion remedial works at Scotts Creek, Curdies (2006/07) Gully erosion located near Scotts Creek in the Curdies catchment was damaging farm fences and agricultural land. Erosion was contributing sediment into Coorimungle Creek. The funded project involved the installation of a drop pipe structure to take water flowing off the surrounding catchment to the gully floor with out causing any further erosion. This was done with the assistance of diversion banks which channelled water to the structure. The surrounding area has been fenced and revegetated by the farmer. Gully erosion stabilisation at Timboon, Curdies (2006/07) A gully had formed in this landholders paddock due to runoff being concentrated at a point from a culvert under the Timboon and Warrnambool Road near Timboon. The site require diversion banks and an under ground pipe system to drain the paddock. The main asset at risk was the loss of good agricultural land. However, the site had potential to increase in erosion areas and threaten nearby creeks and roads. Landslide drainage works at Simpson, Curdies (2006/07) An old landslide site off the Coradjil Rd near Simpson has been unusable by the owners for many years due to natural springs which flow through out the year. The works completed here involved undergrowned drainage in the form of muldrains of the slope. This has allowed stock to access the paddock without damaging the soil structure due to pugging. |

Moorabool Gorge Recovery Program Victoria’s Moorabool River is a proclaimed water supply catchment and provides drinking water to Ballarat, Geelong and several smaller towns in between. The quality of water in the river has been declining over the past ten years due to increasing salinity, sedimentation and nutrification. Much of this decline can be attributed the land management practises within the catchment. For example land that is bared due to overgrazing and drought is much more prone to erosion from wind and water and often ends up in waterways. The Moorabool Gorge Recovery Program was set up in 2001 to provide technical advice and incentives for works promoting positive water quality outcomes. The project was initiated by the landcare community and has been fully supported by the Moorabool Shire, Barwon Water, Corangamite Catchment Management Authority and The Department of Primary Industries. This multi-agency partnership is unique in the region and has become an example of how diverse organisations can work together for shared outcomes. Many lessons have been learned over the past seven years. These range from practical tips for successful revegetation to effective ways of working with individuals and groups. There have been resounding successes and some failures as well. The main achievements of the project include protecting 461 hectares of remnant vegetation, enhancing over 48 kilometres of waterways and revegetating 662 hectares with over half a million seedlings. An evaluation of the past seven years of the project is currently underway. This will help to clarify what the project has achieved. It will also assist in determining if the project has met the expectations of the people who have invested in it. As there are plans to continue the program, the evaluation will also help to refocus the project and make recommendations for improvement..

Corangamite region improves soil health The Sustainable Landscapes Corangamite Team are working with landholders to address soil health issues. The team have addressed erosion issues through a Community Engagement Pilot and Incentive Program. Landholders in the Moorabool River catchment have identified erosion as one of their biggest environmental threats. Soil Health Officer Shari McConachy contacted landholders to establish the level of priority and the extent of the threat to their property. Some landholders considered soil erosion a priority ahead of weeds and rabbits and are proactive in attempting to remediate active erosion sites. Long-time landholder Lance Wray has completed extensive earthworks on a large erosion gully on his property with the assistance of the Soils and Salinity Incentive Program. The large-scale earthworks battered the seven-metre gully and helped establish vegetation on the 14-hectare site. Lance feels it is important to improve the property's value and environmental sustainability for the next generation.
