Southern Rural Water (SRW) is developing a Local Management Plan (LMP) for the deeper aquifers of South West Victoria, known as the “Otway lower aquifers”. The LMP covers the Clifton (Condah) and Lower Tertiary (Dilwyn) aquifers between the Otway Ranges and the South Australian border.

Shallow aquifers (the basalt and limestone aquifers) overlie but are not well connected to the lower aquifers. The basalt aquifer is managed by the Glenelg, Portland and Hopkins-Corangamite GCS_Final April 2016 Catchment Statement The limestone aquifer is managed by the South West Limestone Local Management Plan

The LMP will improve and simplify groundwater management within the existing Glenelg and Condah Water Supply Protection Areas (WSPAs), the Portland, Parratte and Newlingrook Groundwater Management Areas (GMAs) and surrounding areas.
