Wr1 Surf Parade Bridge Inverloch

Active Physico-Chemical Surf Parade Inverloch

Centre culvert on the downstream (ocean) side of Surf Parade Bridge


Park on the Inverloch side of the Surf Parade Bridge. Step over the hand railing and complete the monitoring from the centre culvert.

Land Use

Creek flows from above the RACV resort in Inverloch (branch 1) and through the housing estate (i.e. residential area) in Inverloch (branch 2), into a coastal reserve where the majority of the estuary exists.
