Lake Dulverton is a large shallow lake/lagoon associated with the town of Oatlands in Southern Midlands of Tasmania. The lake has an uneven shoreline with many low sandstone cliffs and overhangs. The only island in the lake, Mary's Island, is a small sandstone rock roughly 80 m long with nothing more than a few cedars growing on it. The lake dried up in 1993 and remained dry for years until heavy rains in August, 2010, filled the lake to near full supply level. During this dry period, 2 levees were built across the lake dividing it into 3 sections. Only the smallest section near the Callington Mill was able to remain full.

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. The lake is currently part of a wildlife sanctuary.
