After passing [[Fosdyke Bridge]] the river passes into [[Moulton, Lincolnshire|Moulton Marsh]] where it is joined by the Holbeach River, the river from this point then enters a area of extensive salt marshes with estuary like features which make up what is known as 'The Fosdyke Wash' at the very south-western edge of [[The Wash]] where the salt marshes becomes indistinguishable from the sea and from here the river quickly loses the traditional characteristics of being a river as the main river banks move away from the river itself at this point to become the main sea embankments and this leaves the river without a distinguishable mouth as it merely becomes a deep tidal channel known as the “Welland Outfall”, where it finally flows into The Wash itself in a area known as the 'Boston Deeps' at Tabs Head, where it also meets the mouth of [[The Haven, Boston|The Haven]] close to the [[RSPB]] nature reserve at [[Frampton Marsh]].<ref name=FWgam/><ref name=osmap/>
