Cylch 1 Cyrff Dŵr Llyn y Gyfarwyddeb Fframwaith Dŵr (WFD)
Mae ‘Cyrff Dŵr Llyn y Gyfarwyddeb Fframwaith Dŵr (WFD)’ yn set ddata ofodol sy'n crynhoi priodoleddau WFD sydd wedi'u casglu fel y diffiniwyd ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr (WFD). Mae Erthygl 2, cymal 5 y WFD yn diffinio cyrff dŵr llyn fel ‘…corff o ddŵr wyneb llonydd mewndirol’. Gellir cysylltu data ar nodweddion ffisegol, risg, dosbarthiad ac amcanion arfaethedig i'r cyrff dŵr gyda'u dynodwyr unigryw. Mae llynnoedd artiffisial a llynnoedd wedi'u haddasu'n cael eu cynnwys yn y set ddata: fodd bynnag, yn gyffredinol, dim ond llynnoedd dros 50 hectar a aseswyd dan y WFD heblaw am lynnoedd mewn ardaloedd gwarchodedig, lle defnyddiwyd trothwy o 5.0ha. Nid yw llynnoedd llai na'r trothwy hwn yn cael eu cynnwys oni bai bod ganddynt ddynodiad SoDdGA. Mae gan bob corff dŵr ddynodwr unigryw EA_WB_ID sy'n golygu y gellir ei gysylltu â phriodoleddau WFD. Mae'r data'n berthnasol i Gylch 1 y Gyfarwyddeb Fframwaith Dŵr.

Artificial and modified lake waterbodies are included within this dataset; however, generally only lakes above > 50 hectares were assessed under the WFD except for lakes in protected areas, where a minimum of 5.0 ha was used. Lakes below this threshold are not included within this dataset unless allocated as Sites of Special Scientific Interest (SSSI). Each waterbody has been assigned 'EA_WB_ID', which is a unique identifier that enables a link to WFD attributes. These data apply to Cycle 1 of the Water Framework Directive and contains Ordnance Survey (OS) data.
