River Suck

The River Suck (Irish: An tSuca [n tk]) is a 133 km (82.5 mi) long river in the Shannon River Basin in Ireland. It is the River Shannon's primary tributary. It meets the Shannon about a kilometer south of Shannonbridge. The River Suck drains 1,599 square kilometers of land (617 sq mi).

River Suck flows along the western side of County Roscommon, forming part of the border between County Roscommon and County Galway. It forms the long, thin shape of southern County Roscommon when joined to the Shannon on the east. The river flows through unspoiled terrain with moorland, water meadows, and pastureland, and the water is clear and unpolluted.

Some sections move quickly, while others are languid and meandering. Bream, rudd, and tench are prevalent in some areas, while perch and pike are also frequent. In 1885, a weir was built just above the four-arch bridge to avoid flooding at Ballinasloe, with draw-doors that may be lifted when a flood is coming. It is considered one of the longest rivers in Ireland.
