Article 2, clause 2 of the WFD defines them as '...all water which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil'. For the purposes of reporting under the WFD a groundwater body represent a distinct body of groundwater flow with a coherent flow unit including recharge and discharge areas with little flow across the boundaries. These reflect hydrogeological characteristics containing information on flow and stage properties, recharge and vulnerability to pollution. This has been undertaken through defining aquifers into different types and broken into catchment units at Catchment Abstraction Management Strategy (CAMS) scale. Since water bodies are attributed with a unique identifier (EA_WB_ID) this dataset can be linked directly to other WFD data sources such as physical characteristics, risk, classification and proposed objectives.

Mae cyrff dŵr daear Cylch 1 y Gyfarwyddeb Fframwaith Dŵr yn set ddata ofodol (polygon) sy'n cynnwys nodweddion sydd wedi cael eu coladu fel y diffiniwyd ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr. Mae Erthygl 2, Cymal 2 y Gyfarwyddeb Fframwaith Dŵr yn eu diffinio fel 'yr holl ddŵr sy'n is na wyneb y tir yn y parth trwytho ac mewn cyswllt uniongyrchol â'r tir neu isbridd'. At ddibenion hysbysu o dan y Gyfarwyddeb Fframwaith Dŵr, mae corff dŵr daear yn cynrychioli corff penodol o lif dŵr daear gydag uned llifo gydlynol, gan gynnwys ardaloedd adlwytho a rhyddhau, gydag ond ychydig o lif ar draws y terfynau. Mae'r rhain yn adlewyrchu nodweddion hydrodaearyddol sy'n ystyried gwybodaeth am nodweddion llif a chamau, adlwytho, a pha mor agored ydynt i lygredd. Mae hyn wedi cael ei gynnal trwy ddiffinio dyfrhaenau o ran teipiau gwahanol a'u rhannu’n unedau dalgylch ar raddfa Strategaethau Rheoli Tynnu Dŵr Dalgylch. Gan fod cyrff dŵr wedi'u penodi gyda rhif adnabod unigryw (EA_WB_ID), mae'r set ddata hon yn gallu cael ei chysylltu'n uniongyrchol â ffynnonnellau data eraill y Gyfarwyddeb Fframwaith Dŵr megis nodweddion corfforol, risg, dosbarthiad ac amcanion arfaethedig.
