Nenagh River

The Nenagh River (Irish: An Ghaothach) rises in the Silvermine Mountains in County Tipperary, Ireland. It flows east of Nenagh and into Lough Derg just north of Dromineer.

Recreation
The river, and its tributary the Ollatrim river, is popular for angling, it holds a stock of wild salmon and trout. There are also coarse fish particularly near the mouth of the river during spawning times. Funds were allocated to the Ormonde Anglers Association to improve areas for spawning and in-stream structures improving access, fencing, protecting banks and installing a number of deflectors. There is 22 km of trout fishing and a further 15 km on the Ollatrim. It is classified as a rich lowland river.

Slí Eala ("Way of the Swan") was a 10 km waymarked trail which follows the banks of the Nenagh River from Dromineer via Ballyartella to Scott's Bridge, on the N52 road north of Nenagh. The walk takes its name from the population of mute swans on the river. There were trailheads at Scott's Bridge and in Dromineer village. This walk is no longer maintained and is blocked in places on the farmland where it was once situated.

Bridges
There are several bridges over the river.
