Local Water Resource Availability for abstraction licensing is provided in our Abstraction Licensing Strategies (ALS) published on our website. ALS outline the implications for abstraction licensing of the different water resource availability colours. This national picture of Water Resource Availability may be different to local assessments in ALS particularly for regulated rivers and rivers designated as Special Areas of Conservation (SACs) where local requirements may mean that results have been overridden.

Seiliwyd y data Argaeledd Adnoddau Dŵr ar ddull cenedlaethol cyson ac maent yn rhoi darlun o Argaeledd Adnoddau Dŵr ar gyfer pob corff dŵr Cylch 2 o dan y Gyfarwyddeb Fframwaith Dŵr. Darperir gwybodaeth am Argaeledd Adnoddau Dŵr Lleol at ddibenion trwyddedu tynnu dŵr yn ein Strategaethau Trwyddedu Tynnu Dŵr a gyhoeddir ar ein gwefan. Mae’r Strategaethau Trwyddedu Tynnu Dŵr yn nodi goblygiadau’r gwahanol liwiau argaeledd adnoddau dŵr ar drwyddedu tynnu dŵr. Gallai’r darlun cenedlaethol o Argaeledd Adnoddau Dŵr fod yn wahanol i’r asesiadau lleol a wneir mewn Strategaethau Trwyddedu Tynnu Dŵr, yn enwedig felly ar gyfer afonydd wedi’u rheoleiddio ac afonydd a ddynodwyd yn Ardaloedd Cadwraeth Arbennig, lle gallai’r gofynion lleol olygu bod y canlyniadau wedi’u diystyru. Disgrifiadau Argaeledd Adnoddau Dŵr - Gwyrdd: Dŵr ar gael i’w drwyddedu - Melyn: Dŵr cyfyngedig ar gael i’w drwyddedu - Coch: Nid yw’r dŵr ar gael i’w drwyddedu - Llwyd: Cyrff dŵr wedi’u haddasu’n sylweddol a/neu ddalgylchoedd sy’n gollwng llawer o ddŵr Nid data crai mo’r rhain, ac nid ydynt yn ffeithiol nac yn fesuredig. Amcangyfrifon neu ganlyniadau wedi’u modelu ydynt, sy’n dangos y canlyniadau y gellir eu disgwyl ar sail y data sydd ar gael inni.
