Mae’r set ddata’n cynnwys manylion pob trwydded tynnu dŵr fyw yng Nghymru. Mae trwyddedau sydd wedi dod i ben neu sydd wedi’u dirymu wedi’u heithrio. Mae’r tabl yn cynnwys manylion yr uchafswm blynyddol a dyddiol o ran tynnu dŵr. Y symiau hyn yw’r uchafswm a ganiateir o dan y drwydded; maent yn rhoi arwydd ynglŷn â maint y gwaith tynnu dŵr. Gall rhai trwyddedau gynnwys amodau cydgasglu neu amodau eraill sy’n cyfyngu ar y gwaith tynnu dŵr; nid yw’r rhain wedi’u cynnwys yn y set ddata. Rhybudd gwybodaeth Golygiadau Mae rhan o’r set ddata hon yn sensitif ac mae wedi’i golygu, a gellir ei hailddefnyddio dim ond yn unol â thelerau trwydded CNC. Gall y set ddata nas golygwyd fod ar gael ar gais drwy anfon Ffurflen Gais Ddata wedi’i llenwi at dîm Dosbarthu Data CNC: datadistribution@cyfoethnaturiolcymru.gov.uk Trwyddedau a ddadreoleiddiwyd Cafodd rhai trwyddedau eu dadreoleiddio ar 31 Mawrth 2005. Mae trwyddedau sydd wedi’u dadreoleiddio yn cynnwys unrhyw waith o dynnu llai nag 20 metr ciwbig o ddŵr y dydd o ffynhonnell dŵr wyneb (e.e. nant neu ddraen) neu o strata tanddaearol (drwy dwll turio neu ffynhonnell), at unrhyw ddiben penodol. Felly, nid oedd modd trwyddedu gwaith tynnu dŵr mwyach os oedd yn perthyn i’r categori hwn, ac fe’i dirymwyd. O ganlyniad, mae’n bosibl bod gwaith tynnu dŵr sydd wedi’i ddadreoleiddio ac achosion eraill o dynnu dŵr heb drwydded yn eich ardal o ddiddordeb, yn arbennig at ddefnydd domestig neu amaethyddol, neu nad yw trwyddedau a ddadreoleiddiwyd a oedd yn hysbys cyn 31 Mawrth 2005 yn weithredol mwyach. Felly, ni fydd yr achosion hyn o dynnu dŵr yn cael eu cynnwys yn y data Gwaith Tynnu Dŵr Trwyddedig a gyflenwyd. Mae rhagor o wybodaeth am yr amserlenni ar gyfer trwyddedu gwaith tynnu dŵr a oedd wedi’i eithrio o’r blaen, ac esemptiadau sy’n weddill, ar gael ar ein gwefan.

Expired, lapsed and revoked licences are excluded. The table holds details of maximum annual and maximum daily abstraction quantities. The quantities are the maximum permitted under the licence; they give an indication of the size of the abstraction. Some licences may include aggregating conditions or other conditions which restrict the abstraction; these are not included in the dataset. Data stored from 2013-04-01 to 2016-02-26 in WISKI and from 2016-02-27 to present in PALS. Some of the data is considered sensitive, a redacted public version of the data is available, requests for the full data will be consider on a case-by-case basis. Information warning; Deregulated Licences Some licences were deregulated on 31st March 2005. Deregulated licences include any abstraction of less than 20 cubic metres per day from a surface water source (e.g. stream or drain) or from underground strata (via borehole or well) for any particular purpose. Abstractions were therefore no longer licensable if they fell into this category and revoked. It is therefore possible that there are deregulated abstractions and other unlicensed abstractions present in your area of interest, particularly for domestic or agricultural use or that deregulated licences known before 31st March 2005 are now no longer active. So these abstractions will not be included in the supplied Licensed Water Abstraction data.
