It is the main tributary of the\u00a0River Shannon<\/a>. It meets the Shannon a kilometre south of the village of\u00a0Shannonbridge<\/a>.<\/p>\n The river’s name is derived from the Irish\u00a0suca<\/i>, of uncertain meaning, possibly deriving from\u00a0succ\u00edn<\/i>,\u00a0Middle Irish<\/a>\u00a0for “amber<\/a>.”<\/sup>Edmund Hogan’s\u00a0Onomasticon Goedelicum<\/i>\u00a0records the spellings\u00a0su\u0121<\/i>\u00a0(sugh<\/i>), suggesting connections to\u00a0Old Irish<\/a>\u00a0s\u00fag<\/i> (“juice, sap”)<\/sup><\/p>\n The River Suck drains an area of 1,599 square kilometres (617\u00a0sq\u00a0mi).<\/sup>\u00a0It forms much of the border between\u00a0County Roscommon<\/a>\u00a0and\u00a0County Galway<\/a>, 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.<\/sup><\/p>\n The river rises in hills on the border of\u00a0County Mayo<\/a>\u00a0and\u00a0County Roscommon<\/a>, and passes from\u00a0Lough O’Flynn<\/a>\u00a0in a general south and south-easterly direction. Settlements along the river include\u00a0Athleague<\/a>,\u00a0Ballinasloe<\/a>,\u00a0Ballyforan<\/a>,\u00a0Ballymoe<\/a>,\u00a0 Castlerea<\/a>,\u00a0Glinsk<\/a>, and\u00a0Tulrush<\/a>, and it flows into the\u00a0River Shannon<\/a>\u00a0a kilometre south of the village of\u00a0Shannonbridge<\/a>.<\/sup><\/p>\n<\/div> The water is clean and unpolluted and the river flows through unspoilt countryside with moorland,\u00a0water meadows<\/a>\u00a0and pastureland. Some stretches are fast-flowing while others are slow and meandering. There are abundant\u00a0bream<\/a>,\u00a0rudd<\/a>\u00a0and\u00a0tench<\/a>\u00a0in some parts, and\u00a0perch<\/a>\u00a0and\u00a0pike<\/a> are also plentiful.\u00a0<\/sup>To prevent flooding at Ballinasloe, a weir was erected in 1885 immediately above the four-arch bridge, with draw-doors which can be raised when there is an approaching flood.<\/sup><\/p>\n<\/div><\/span><\/div><\/span><\/div>
