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.

Mae cyrff dŵr daear Cylch 2 y Gyfarwyddeb Fframwaith Dŵr (2014-2019) yn set ddata ofodol (polygon) sydd wedi'i chreu ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr. Mae Erthygl 2, Cymal 2 y Gyfarwyddeb Fframwaith Dŵr yn eu diffinio fel '…yr holl ddŵr sydd o dan wyneb y ddaear yn y parth trwytho ac mewn cyswllt uniongyrchol â'r tir neu'r isbridd'. At ddibenion hysbysu o dan y Gyfarwyddeb Fframwaith Dŵr, mae corff dŵr daear yn cynrychioli corff penodol o lif dŵr daear gydag uned lifo gydlynol, gan gynnwys ardaloedd adlwytho a rhyddhau, gydag ond ychydig o lif ar draws y terfynau. Mae'r rhain yn adlewyrchu nodweddion hydroddaearegol sy'n ystyried gwybodaeth am nodweddion llif a cham, adlwytho, a pha mor agored ydynt i lygredd.
