Mullutu-Suurlaht (also Mullutu Suurlaht) is the fourth largest lake in Estonia{{citation needed|date=April 2016}}. It is located on the island of Saaremaa, about {{Convert|2|km|}} west of the town of Kuressaare. It has an area of {{convert|1440|ha|acre|abbr=on}} and the max. depth is {{convert|2.1|m|ft}}.{{cite web|title=Mullutu Suurlaht|url=http://www.eestigiid.ee/?SCat=38&CatID=0&ItemID=779|publisher=eestigiid.ee|accessdate=1 June 2012|language=Estonian}} Mullutu-Suurlaht is a brackish waterbody that consists of two parts:

• Suurlaht or Kellamäe Bay ({{convert|531|ha|acre|abbr=on}}, eastern part){{cite web|title=Suurlaht / Kellamäe laht|url=http://loodus.keskkonnainfo.ee/webeelis/infoleht.aspx?obj=veekogu&id=-1640000269|archive-url=https://archive.today/20130213035342/http://loodus.keskkonnainfo.ee/webeelis/infoleht.aspx?obj=veekogu&id=-1640000269|url-status=dead|archive-date=13 February 2013|publisher=EELIS – Estonian Nature Infosystem|accessdate=1 June 2012|language=Estonian}}
• Mullutu Bay or Great Mullutu Bay ({{convert|412.4|ha|acre|abbr=on}}, western part){{cite web|title=Mullutu laht|url=http://loodus.keskkonnainfo.ee/webeelis/infoleht.aspx?obj=veekogu&id=-1428217350|archive-url=https://archive.today/20130213060824/http://loodus.keskkonnainfo.ee/webeelis/infoleht.aspx?obj=veekogu&id=-1428217350|url-status=dead|archive-date=13 February 2013|publisher=EELIS – Estonian Nature Infosystem|accessdate=1 June 2012|language=Estonian}}

During the regular flood in spring (usual rise is {{Convert|0.75|m|}}, max {{Convert|1.16|m||abbr=on}}) Mullutu-Suurlaht merges with nearby Paadla, Vägara and Kaalupea bays and draws a temporary waterbody up to {{convert|3600|ha|acre|abbr=on}}. Mullutu-Suurlaht is drained by the {{Convert|3|km||-long|abbr=on|adj=mid}} Nasva River. Due to a strong connection with sea through Nasva river the lake is rich in fish, main species include bleak, burbot, crucian carp, dace, eel, gudgeon, ide, perch, pike, ruffe, roach, rudd and tench.
