'''Sleaford Bay''' is a [[bay]] located in the Australian state of [[South Australia]] on the southern coast of [[Eyre Peninsula]]. It was named by the British navigator, [[Matthew Flinders]] in 1802.
==Extent & description== Sleaford Bay is located on the south coast of Eyre Peninsula in South Australia about {{convert|21|km}} south-west of the municipal seat of [[Port Lincoln]].<ref name=LMV/>
It lies between the headland of [[Cape Wiles]] at its western extremity and headland of [[Cape Tournefort]] at its eastern extremity. A subsidiary bay named '''Fishery Bay''' is located on its west side about {{convert|2|nmi|km mi}} north of Cape Wiles.<ref name=Pub175>{{cite enroute|175|2017|183}}</ref>
==History== The bay was named after the town of [[Sleaford]] in [[Lincolnshire]], [[England]] by the British navigator, [[Matthew Flinders]] in 1802.<ref name=manning/>
The [[Barngarla language|Barngarla]] name for Sleaford Bay is ''Dhanana''.<ref name=b>[[Ghil'ad Zuckermann|Zuckermann, Ghil'ad]] and the Barngarla (2019), [https://www.adelaide.edu.au/directory/ghilad.zuckermann?dsn=directory.file;field=data;id=41076;m=view''Barngarlidhi Manoo (Speaking Barngarla Together)''] {{Webarchive|url=https://web.archive.org/web/20200526193430/https://www.adelaide.edu.au/directory/ghilad.zuckermann?dsn=directory.file&field=data&id=41076&m=view |date=26 May 2020 }}, Barngarla Language Advisory Committee.

=== Proposed seawater desalination plant === In 2018, a proposal to construct a 3 gigalitre per year seawater desalination plant at Sleaford Bay{{where|date=April 2019}} was announced. Land was purchased in July and the project was expected to cost $80 million to complete.<ref>{{Cite news|url=https://www.sbs.com.au/news/sa-plans-for-80-million-desal-plant|title=SA plans for $80 million desal plant|work=SBS News|access-date=2018-11-28|language=en-GB|archive-date=29 November 2018|archive-url=https://web.archive.org/web/20181129012820/https://www.sbs.com.au/news/sa-plans-for-80-million-desal-plant|url-status=live}}</ref><ref>{{Cite news|url=https://www.portlincolntimes.com.au/story/5756461/desal-plant-talks/|title=Desal plant talks|last=Cootes|first=Isobel|date=2018-11-13|work=Port Lincoln Times|access-date=2018-11-28|language=en|archive-date=28 November 2018|archive-url=https://web.archive.org/web/20181128210934/https://www.portlincolntimes.com.au/story/5756461/desal-plant-talks/|url-status=live}}</ref> The location is one of several prospects previously earmarked by [[SA Water]] in 2009.<ref>{{Cite news|url=https://www.abc.net.au/news/2009-12-02/three-sites-earmarked-for-eyre-peninsula-desal/1165244|title=Three sites earmarked for Eyre Peninsula desal|date=2009-12-02|work=ABC News|access-date=2018-11-28|language=en-AU|archive-date=30 October 2016|archive-url=https://web.archive.org/web/20161030013736/http://www.abc.net.au/news/2009-12-02/three-sites-earmarked-for-eyre-peninsula-desal/1165244|url-status=live}}</ref> In 2020, the site in the north of the bay near Sleaford Mere Conservation Park was ruled too costly. After a second site closer to Port Lincoln was opposed by commercial fisheries in 2021, a committee was set up which chose a site between Fishery Bay and Sleaford Bay in 2022, with the capacity increased to 5.3-gigalitres.<ref>{{Cite news |date=2022-08-10 |title=Third time's a charm as locals choose new Sleaford Bay site for Eyre Peninsula desalination plant |url=https://www.abc.net.au/news/2022-08-10/new-sleaford-bay-site-chosen-for-ep-desalination-plant/101319878 |access-date=2024-01-09 |work=ABC News |language=en-AU}}</ref> Most recently SA Water has decided to build within Proper Bay near Port Lincoln. This is being resisted as consultation and native title research has not been completed and the decision goes against the advice of the local management board and it's findings. The area is known to frequently have low to no tidal flushing during Dodge tide events, particularly during the hottest months, which has raised grave concerns from commercial operators and some marine biologists should the area become adversely affected. An announcement that the initial Desalination plant size is projected to expand significantly in the future also creates uncertainty within the broad local community.
