Sluice Gates
Water levels on the River Shannon are managed using gates and sluices at the outlets of the three major lakes, and sluices and weirs at Jamestown, Roosky, Tarmonbarry, Meelick, and the New Cut. Despite these operations, the shallow gradient and natural restrictions prevent full control, especially during floods. River levels are mainly determined by rainfall in the catchment area.
Current sluice gate and water levels information can be viewed on the Waterways Ireland website.
