Yenyenning Lake, also often spelt Yenyening Lakes, and associated lakesThe saline lakes associated with Yenyenning Lake are often referred to as the Yenyenning Lakes or the Yenyenning Lake System: {{Citation | author1=Western Australia.

It is located in the Wheatbelt region of Western Australia approximately {{cvt|31|km}} north east of Brookton.{{Citation | author1=Anderton, P. W.

The lakes are part of what are called playa lake chains, and the system is often referred to as an example.{{Citation | author1=Davis, Jennifer | author2=Carling, Paul | title=Playa lake chains: the example of the Yenyening Lakes of the upper Avon River catchment of Western Australia | publication-date=2012 | publisher=Springer | url=http://trove.nla.gov.au/work/192501582 | access-date=19 November 2016 }}
The {{cvt|13000|ha|adj=on}} catchment area is composed of alluvial and aeolian deposits; it receives an average annual rainfall of {{cvt|452|mm}} and has an annual evaporation rate of {{cvt|2004|mm}}. The lakes are found along major ancient drainage lines with a broad drainage floor over a paleochannel and at the meeting point of the zone of
ancient drainage and the zone of rejuvenated drainage. The larger lakes in the system are separated by sandy rises, saline drainage floors and diffuse drainage lines.
Situated in the Wheatbelt region, the lakes have had adjoining land heavily used for agriculture since European settlement in the region.{{Citation | author1=Western Australia.

The lakes, which are a wildlife haven, were often referred to as the County Peak lakes{{cite news |url=http://nla.gov.au/nla.news-article201780080 |title=Lakes "a wild life haven" |newspaper=The Beverley Times |volume=67 |issue=16 |location=Western Australia |date=5 May 1972 |access-date=23 October 2017 |page=1 |via=National Library of Australia}} and can be seen from the summit of nearby County Peak.{{cite news |url=http://nla.gov.au/nla.news-article202732724 |title=Tourist Road at County Peak |newspaper=The Beverley Times |volume=62 |issue=22 |location=Western Australia |date=10 June 1966 |access-date=23 October 2017 |page=1 |via=National Library of Australia}}
The resultant problems, including salinity issues, have been researched and investigated extensively.{{Citation | author1=Cooper, C.
