Cyflwyniad i'r ddogfen hon Mae Rheoliadau'r Amgylchedd Dŵr (Y Gyfarwyddeb Fframwaith Dŵr) (Cymru a Lloegr) 2017 (y cyfeirir atynt fel Rheoliadau’r Gyfarwyddeb Fframwaith Dŵr 2017) yn darparu'r prif fframwaith ar gyfer rheoli'r amgylchedd dŵr yng Nghymru. Wrth wraidd y rheoliadau mae dull rheoli ar lefel yr ecosystem a dull seiliedig ar ddalgylch sy'n ei gwneud yn ofynnol i fesurau gael eu cymryd i annog defnydd cynaliadwy o ddŵr ac i amddiffyn a gwella'r amgylchedd dŵr, gyda'r nod o sicrhau statws da. Maent yn cydnabod bod angen i grwpiau sydd â diddordeb gydweithio gyda'i gilydd er mwyn cynllunio a gweithredu'r gwelliannau, gan fabwysiadu dull cyfannol ac integredig ar gyfer rheoli'r amgylchedd dŵr. O dan Reoliadau'r Gyfarwyddeb Fframwaith Dŵr 2017, rhaid datblygu Cynllun Rheoli Basn Afon ar gyfer pob ardal basn afon. Caiff y cynlluniau hyn eu cyhoeddi'n gyntaf ym mis Rhagfyr 2009. Maent yn amlinellu'r camau gweithredu sydd angen eu cymryd er mwyn sicrhau statws da ar gyfer mwy o ddyfroedd. Rhaid i'r cynlluniau (yn ogystal â’r amcanion a'r mesurau sydd ynddynt), gael eu hadolygu a'u diweddaru bob chwe blynedd. Mae Cyfoeth Naturiol Cymru yn arwain ar gyhoeddi’r Cynlluniau Rheoli Basn Afon ar gyfer Gorllewin Cymru ac afon Dyfrdwy, ond mae Asiantaeth yr Amgylchedd yn arwain ar gyhoeddi'r Cynllun Rheoli Basn Afon ar gyfer afon Hafren. Mae Rheoliadau'r Gyfarwyddeb Fframwaith Dŵr 2017 yn nodi bod rhaid cynnal ymgynghoriad cyhoeddus ar fersiynau drafft o'r Cynlluniau Rheoli Basn Afon am chwe mis. Mae'r ddogfen hon yn amlinellu'r manylion sydd y tu ôl i'r broses o wneud penderfyniadau sydd wedi llywio’r diweddariad hwn o'r Cynlluniau Rheoli Basn Afon drafft yng Nghymru. Mae'n esbonio pob cam yn y broses, gan gysylltu â gwybodaeth fanylach lle y bo'n briodol. Gwybodaeth ategol Mae llawer o'r data sy'n ategu'r cynllun hwn ar gael ar gyfer pob corff dŵr yng Nghymru ar wefan Arsylwi Dyfroedd Cymru gan gynnwys: • · Canlyniadau'r broses ddosbarthu • · Rhesymau dros beidio â chyflawni statws da • · Amcanion cyrff dŵr • · Rhesymau dros amcanion statws eraill • · Rhwydweithiau monitro • · Mesurau sydd eu hangen er mwyn gwella cyrff dŵr i sicrhau statws da • · Cyrff dŵr a addaswyd yn sylweddol 1.1 Yr hyn a gwmpesir gan y ddogfen hon Mae Rheoli'r amgylchedd dŵr (yr adran nesaf) yn disgrifio pam fod dŵr yn adnodd mor bwysig ac yn crynhoi'r polisïau sy'n llywio sut mae’r amgylchedd dŵr yng Nghymru yn cael ei reoli. 4 Mae Rheoliadau'r Gyfarwyddeb Fframwaith Dŵr 2017 (adran 3) yn disgrifio nodau ac amcanion Rheoliadau’r Gyfarwyddeb Fframwaith Dŵr 2017, gan gynnwys cymhwyso esemptiadau. Disgrifir y broses a ddefnyddir yng Nghymru ar gyfer cynllunio gwaith rheoli basn afon, gan gynnwys
