Chichester Dam was constructed between 1917 and 1926 and is a minor concrete gravity dam, upstream of Dungog, in the Hunter Region. One of the Hunter's most important freshwater storage facilities contributing about 35 per cent of the Lower Hunter's potable water supply. The dam wall is 254 metres long and 43 metres high and is anchored to the bedrock below the wall by 93 stressed tendons. The catchment for Chichester Dam is largely within the Barrington Tops National Park, and as a result it is one of the most pristine catchments in Australia. Wood is located in near barbecue or bring own gas barbecue. No dogs are allowed so leave the pooch at home. All the roads within the site are sealed and can be accessed by coaches.
