Estuary name Merri River Estuary
CMA Glenelg Hopkins CMA

The Merri Estuary is located near Warrnambool in southwest Victoria. The river has two openings to the sea, both artificially modified. In 1859, the course of the Merri River was diverted in an attempt to prevent sedimentation in Lady Bay (Gill 1984). The main channel of the Merri River now discharges into the sea at Stingray Bay east of Pickering Point.
