Lake Dulverton is a 230-to-233-hectare (570-to-580-acre)[2] shallow lake or sandstone lagoon located adjacent to the town of Oatlands in the Southern Midlands region of Tasmania, Australia.

The lake has an uneven shoreline with many low sandstone cliffs and overhangs.

During this dry period, two levees were built across the lake dividing it into three sections.

The floor of the lake is composed of peaty soils, rock and sand.

When full, the waters of the lake quickly fill with pondweed and numerous waterbirds.
