The lake was originally created as a railway dam on the Eastern Railway and is now part of a 168 hectare recreational park.
The dam holds an estimated 520 million litres of water and is located off Rosedale Road, Chidlow, about a 45 minutes drive from Perth.
Bushwalking, camping, canoeing and swimming are popular activities on and around the lake, as is birdwatching. A cafe, toilets, playground, barbecues, picnic areas, grassed areas and walking trails are all available, as are shaded areas and white sand beaches.
The Shire of Mundaring manages the recreational facility adjacent to the lake and charges a small entry fee. The location is very popular with visitors during summer, especially on the weekends.
Native trees including Marri and Wandoo, plus wildflowers surround the lake, and an abundance of bird life including ducks, geese, herons and swamp hens can be seen. Plus, kangaroos, possums, bandicoots and echidnas can be found in the surrounding native bushlandNearby places
