Lake William Hovell is a man-made lake in north-eastern Victoria, Australia. Formed by a dam on the King River, the water level in the lake can vary considerably. It is situated south of Whitfield on the edge of the Alpine National Park.
The lake is named after explorer William Hovell. It supplies water for irrigated crops, vineyards and grazing properties along the King River from Cheshunt to Wangaratta. Construction of the earth and rockfill dam was completed in 1973.
It is a very popular destination for kayaking and fishing. Camping is not allowed at the lake.
