Hoffwn ddiolch i bawb a gymerodd ran yn yr uwchgynhadledd – mae gan bob un ohonom ran i'w chwarae o ran gwella ansawdd dŵr yn ein hafonydd a lleihau llygredd ffosfforws.
I would like to thank everyone who took part in the summit – we all have a role to play in improving the quality of water in our rivers and reducing phosphorus pollution.
