Lake Dey Dey is one of many ephemeral salt lakes located in the eastern end of the Great Victoria Desert, in the Far North region of South Australia.
Description
It is normally dry, except during and after periods of heavy rainfall. It is part of the geological basin known as the Officer Basin. The larger Carle Thulka is to the south. Since 1985, Lake Dey Dey is part of the lands belonging to the Maralinga Tjarutja, a southern branch of the Pitjantjatjara. The community of Oak Valley is located nearby to the southwest.{{cite book|author=Odette Mazel|chapter=Returning Parna Wiru: Restitution of the Maralinga Lands to Traditional Owners in South Australia|editor=Marcia Langton|title=Settling with Indigenous People: Modern Treaty and Agreement-making|url=https://books.google.com/books?id=ykiyGUUJqWMC&pg=PA168|publisher=Federation Press|year=2006|isbn=9781862876187|page=168}}
The surface of the lake normally consists of dry clay, silt or sand, covered with a salty crust.{{cite web|title=Environmental impact report: geophysical operations in the Officer Basin, South Australia|url=http://www.pir.sa.gov.au/__data/assets/pdf_file/0015/54231/OBE_EIR_GeoOps_Final_Draft_04092007.pdf|format=PDF|author=Officer Basin Energy Pty Ltd|date=September 2007|page=11|publisher=Government of South Australia, Department of Primary Industries and Regions|access-date=2013-06-15|archive-url=https://web.archive.org/web/20080726214008/http://www.pir.sa.gov.au/__data/assets/pdf_file/0015/54231/OBE_EIR_GeoOps_Final_Draft_04092007.pdf|archive-date=2008-07-26|url-status=dead}} The area around Lake Dey Dey is extremely arid, and groundwater contains high levels of salinity.{{cite web|title=Cyclone Zircon Project Groundwater Feasibility Study|url=https://consultation.epa.wa.gov.au/seven-day-comment-on-referrals/a604099/supporting_documents/8%20Attachment%2012%20Hydrogeology%20report.pdf|format=PDF|publisher=Australian Groundwater Technologies|date=24 February 2012|id=1148-11-DAN|author=Vic Waclawik|pages=8–12; 39}} The elevation of the surface above mean sea level is {{convert|208|m|ft|abbr=on}}.[http://www.ga.gov.au/elvis/ Geoscience Australia elevation data portal]
