Responsibility for the river and the flood defences of the surrounding countryside changed several times during the 20th century. Under the [[Land Drainage Act 1930]], 47 [[catchment area]]s were defined, covering many of the river systems of England and Wales, including the Ancholme and Winterton Beck Catchment Area.{{sfn |Dobson |Hull |1931 |p=113}} A [[catchment board]] had been set up to manage the area by November 1931.{{sfn |Anon |1932 |p=875}} The catchment board was replaced by the Lincolnshire [[river board|River Board]] following the passing of the [[River Boards Act 1948]], and the new board also had responsibility for the [[River Welland]], the [[River Witham]] and the [[Steeping River]]. Land drainage functions became the responsibility of the Ancholme [[internal drainage board|Internal Drainage Board]] from 1951. This was formed under the terms of the Land Drainage Act 1930, and manages an area of {{convert|68.77|sqmi|km2}} containing {{convert|119|mi|km}} of maintained watercourses. Around half of the water falling on this area has to be pumped into the River Ancholme, because the land is too low-lying to allow gravity drainage.<ref>{{cite web |url=http://www.shiregroup-idbs.gov.uk/idbselection.aspx?idb=1609aad4-7ba4-4123-8c56-8f7052b4a031 |archive-url=https://www.webarchive.org.uk/wayback/archive/20150915232437/http://www.shiregroup-idbs.gov.uk/idbselection.aspx?idb=1609aad4-7ba4-4123-8c56-8f7052b4a031 |url-status=dead |archive-date=15 September 2015 |title=Ancholme IDB |publisher=Shire Group of IDBs |access-date=7 November 2015 }}</ref> The IDB maintains 12 pumping stations on the banks of the river.{{sfn |Solomon |Wright |2012 |p=38}}

Responsibility for the river changed again with the passing of the [[Water Resources Act 1963]]: the river board was replaced{{sfn |Wisdom |1966 |p=4}} by the Lincolnshire River Authority, although the geographical area which it managed was similar.{{sfn |HMSO |1963 |pp=143–144}} This in turn became part of [[Anglian Water]] following the passing of the [[Water Act 1973]].<ref>{{Cite web | title= Water Act 1973 |publisher= [[Parliament of the United Kingdom]] | date=18 July 1973 | url= http://faolex.fao.org/docs/pdf/gbr3563.pdf | archive-url= https://web.archive.org/web/20110726045736/http://faolex.fao.org/docs/pdf/gbr3563.pdf | archive-date= 26 July 2011 |url-status=live |pages=47–48}}</ref> When the [[regional water authority|regional water authorities]] were privatised under the terms of the [[Water Act 1989]], management of rivers, including the Ancholme, passed to the [[National Rivers Authority]] (NRA).<ref>{{cite web|url=http://www.legislation.gov.uk/ukpga/1989/15/part/I/crossheading/the-national-rivers-authority-and-the-advisory-committees/enacted|title=Water act 1989 part 1: creation of NRA}}</ref> Finally, the NRA was subsumed into the Environment Agency in 1996.
