It was designed to provide an accurate and consistent assessment of the state of water quality and how it changes over time. These assessments were made for Biological, Chemical and Nutrients and undertaken for discrete river stretches. This is now a static dataset and 2009 was the final year of the scheme.

Y cynllun Prif Ddangosydd Asesiad Ansawdd Cyffredinol oedd y dangosydd cenedlaethol ar gyfer ansawdd dŵr mewn afonydd a chamlesi. Cafodd ei gynllunio i ddarparu asesiad cywir a chyson o gyflwr ansawdd dŵr a sut mae'n newid dros amser. Roedd yr asesiadau hyn ar gyfer olion biolegol, cemegol a maetholion ac fe'u cynhaliwyd ar gyfer darnau afon ar wahân. Mae hwn bellach yn set ddata statig a 2009 oedd blwyddyn derfynol y cynllun.
