It is the main tributary of the River Shannon. It meets the Shannon a kilometre south of the village of Shannonbridge.

The River Suck drains an area of 1,599 square kilometres (617 sq mi).[2] It forms much of the border between County Roscommon and County Galway, flowing along the western side of County Roscommon. Together with the Shannon on the east, it creates the long narrow form of southern County Roscommon, clearly noticeable on maps.



The river's name is derived from the Irish suca, of uncertain meaning, possibly deriving from succín, Middle Irish for "amber."[3]
