Ffin Aber Dyfrdwy

Mewn ymgais i dacluso a diffinio ffin swyddogol rhwng Cymru a Lloegr yn aber Afon Dyfrdwy gan yr Arolwg Ordnans, bu bron i Gymru ildio'i thir i Loegr.

Yn dilyn camau gan yr Arolwg Ordnans i dacluso ar sut caiff eu mapiau eu creu. Nid yw ffin a ddangosir ar fap AO o reidrwydd y ffin cyfriethiol - gall y ddau fod yn wahanol. Dim ond ffin at ddibenion yr AO yw'r hyn a ddangosir ar fap, ond bron pob tro caiff ei dderbyn fel y ffin swyddogol.

Siroedd y codi awydd i

Nid yw'r Arolwg Ordnans erioed wedi dod i gasgliad terfynol ble mae'r ffin yn aber Dyfrdwy, felly dim ond ei nodi at ddibenion ymarferol. Holi'r siroedd i ddod i benderfyniad ble i'w osod, a hynny mwy na thebyg i ddilyn ffin 'gwneud' yr AO.

Elystan Morgan yn codi gan bod y ddadl nid yn unig yn effeithio ar ffiniau sir, ond hefyd ffiniau cenedlaethol, dylai eraill cael ddylanwad.

Yn ôl Statud Rhuddlan yn 1284, yr oedd y ffin cyfreithiol rhwng Sir y Fflint a Swydd Gaer yn dilyn cwrs gwreiddiol Afon Dyfrdwy. Yn dilyn camlaseiddio Afon Dyfrdwy yn y 18fed ganrif, newidwyd ei chwrs yn sylweddol i'r dwyrain o Burton Point ar Gilgwri. Darparwyd trwy Adran 37 Deddf Gyhoeddus 1732, o dan y tetil "An act to recover and preserve the Navigation of the River Dee in the County Palatinate of Chester", na ddylai'r addasiad yng ngwrs sianel yr afon a awdurdodwyd gan y Ddeddf newid nac effeithio ar ffiniau'r ddwy Sir, ac y dylai sianel yr afon fel y bodolai ar y pryd aros yn ffin rhwng y ddwy Sir am byth wedi hynny.

Fodd bynnag, ni ddangosid y wir ffin gyfreithion rhwng Sir y Fflint a chyn-Iarllaeth Balatin Caer a grewyd gan Ddeddf 1732 ar unrhyw fap na chynllun cyfoes aa oedd yn hysbys i'r Cynghorau a gyflwynai'r sylwadau.

Ers 1888, cai'r ffin i'r gorllewin o Burton Point yn yr aber ei dangos ar fapiau'r Arolwg Ordnans ar hyd llinell ganol Aber Dyfrdwy gyda'r geiriau "Boundary between the Counties of Chester and Flint adopted for the purposes of the Ordnance Survey" ac yn sgil Deddf Llywodraeth Leol 1972 newidwyd hyn i ddarllen "Boundary between the Counties of Merseyside and Cheshire and the County of Clwyd adopted for the purposes of the Ordnance Survey".

Dim ond at ddibenion yr Arolwg Ordnans.

Ffiniau'r Arolwg Ordnans yn fympwyol ac heb unrhyw arwyddocâd cyfreithiol.

Yn ôl rhai, mae'r ffin rhwng Cymru a Lloegr yn yr aber wedi bod yn ansicr ers blynyddoedd, barn a rennir gan Mr Wyn Roberts.

River Dee (Anglo-Welsh Boundary) Volume 26: debated on Monday 28 June 1982 Mr. Barry Jones asked the Secretary of State for Wales whether the existing unmarked Anglo-Welsh boundary in the River Dee, close to the Wirral, Cheshire, shore remains the definitive national boundary for the purposes of industrial development and local government planning decisions of his Department; whether his Department have made any studies of the border; and whether consultations have taken place with Alyn and Deeside council. Mr. Wyn Roberts The line of the border between England and Wales in the Dee estuary has been uncertain for many years. The local government boundary commissions of England and Wales are jointly conducting a review of this part of the England—Wales border with a view to removing the uncertainty and establishing a legal boundary.

Yn ôl adran 62 o Ddeddf Llywodraeth Leol 1972, yn dibynnu ble, gall sir alw ar Comisiwn Ffiniau i Gymru neu Comisiwn Ffiniau i Loegr, neu'r ddau ar yr un pryd.

English-Welsh Border (Review By Boundary Commissions) Volume 955: debated on Tuesday 24 October 1978 Mr. Geraint Morgan asked the Secretary of State for Wales (1) if he will list the statutory authority by which the Local Boundary Commission for England proposes, in conjunction with the Local Government Boundary Commission in Wales, to review the border between England and Wales; and whether such a review has his approval;(2) why the proposed review of the border between England and Wales is, in fact, restricted to that part of the national boundary which lies between the county of Clwyd in Wales and the counties of Merseyside and Chester in England;(3) whether he will take steps to ensure that any review of the border between England and Wales will cover the whole of the national boundary with the objective of removing geographical anomalies along its entire length.

Mr. John Morris The statutory authority is section 62 of the Local Government Act 1972, which provides that the Local Government Boundary Commissions for England and Wales, acting jointly, may review the boundary between a county in England and a county in Wales. With the consent of the councils of both counties the commissions may make proposals to my right hon. Friend the Secretary of State for the Environment and myself for boundary alterations and consequential changes to the electoral arrangements considered desirable in the interests of effective and convenient local government. My right hon. Friend and myself may jointly make an order giving effect to the proposals, with or without modifications. Any such order is subject to confirmation by affirmative resolution of both Houses of Parliament. The undertaking of a review under these provisions does not require the approval of my right hon. Friend or myself. Nor do we have any power to direct the commissions to review any particular part of the boundary.The commissions are undertaking the present review in response to a joint request from the three county councils concerned because of long-standing uncertainty as to the boundaries between the counties in the River Dee and the Dee estuary.

Nid oes gan yr Ysgrifennydd i Gymru mo'r pwerau i newid y ffiniau.
