Lee

The River Lee (Irish: An Laoi) is a river in Ireland. It rises in the Shehy Mountains on the western border of County Cork and flows eastwards through Cork city, where it splits in two for a short distance, creating an island on which Cork's city centre is built, then passes through Cork Harbour on the south coast, one of the largest natural harbours in the world, to empty into the Celtic Sea. The catchment area of the River Lee is 1,253 km. The long-term average flow rate of the River Lee is 40.4 cubic metres per second (m/s).

A hydro-electric scheme was built on the river, upstream from Cork City, and this part of the river now contains the Carrigadrohid and Inniscarra reservoirs. The river is crossed by 42 bridges, 29 of which are in Cork City, and one tunnel. The river also provides an 8-kilometre (5.0 mi) stretch of salmon fishing.
