Clayton Bay is a town in South Australia located on Lake Alexandrina and Lower Murray River, part of the lower lakes and Coorong region at the end of the Murray River System. The town is located north of the north-east tip of Hindmarsh Island about from Adelaide and 30.7 kilometres (19 mi) by road from Goolwa.

In 2008, the name of Clayton was officially changed to Clayton Bay by application to the Alexandrina Council and the government of South Australia to avoid confusion with Clayton, Victoria.

Description The wetlands, waters, foreshore and wider environs at Clayton Bay host spectacular sunsets and area attracting national and international environmentalists, ornithologists, bird watchers, photographers, artists, botanists, anthropologists, astronomers and those engaged in ecotourism and water based activities, particularly sailing (popular due to seasonal high wind speeds).

Experience is needed for water activities as the area is very exposed to the wind and the shallow nature of Lake Alexandrina and Lower Lakes creates large choppy waves.Fatal Boat Accident on Lake Alexandrina.

Anyone aboard a motorised boat less than 4.8 metres long must wear a life jacket of all times, and children aged 12 or younger must do so in open areas of boats up to 12 metres in length.

History Aboriginal history The Ngarrindjeri peoples are the Aboriginal Australian Owners of the lower Murray River, eastern Fleurieu Peninsula, and the Coorong of the southern-central area of the state of South Australia. The Ngarrindjeri consist of several distinct if closely related groups, including the Jarildekald, Tanganekald, Meintangk and Ramindjeri, who began to form a unified cultural bloc after Aboriginal peoples were forcibly removed to Raukkan, South Australia (formerly Point McLeay Mission).

Archaeology, particularly in excavations conducted at Roonka Flat, (which affords an outstanding sites for investigating "pre–European contact Aboriginal burial populations in Australia,") have revealed that the traditional lands of the Ngarrindjeri have been inhabited since the Holocene period, beginning around 8,000 B.C. down to around 1840 CE.

For thousands of years, the Lower Murray, Lower Lakes and Coorong region was one of the most densely populated areas of Australia, and the land ( or ) and waterways were home to thousands of Ngarrindjeri peoples. Ngarrindjeri lived in communities in the . Everything Ngarrindjeri needed was present–clean waters, foods, medicines, shelter and warmth.

Ngarrindjeri self-determination, control and management Ngarrindjeri peoples and supporters have challenged and partnered with the South Australian Government for decades, including its natural resource management representatives, over questions of justice, agency, control, sovereignty and the decolonisation of existing and long-standing relationships.

Ngarrindjeri led the development of the Coorong, Lower Lakes and Murray Mouth (CLLMM) Ngarrindjeri Partnerships and Murrundi (Riverine) Recovery Projects. In 2002, the Alexandrina Council made an agreement with the Ngarrindjeri Nation. The agreement included a series of commitments to work together and offers an expression of sorrow and apology to the Ngarrindjeri peoples. It is known as the Kungun Ngarrindjeri Yunnan (KNY) Agreement.
