The River Suir is renowned for its game angling, holding both salmon (Salmo salar) and brown trout (Salmo trutta). The trout fishing water is in the stretch between Holycross village and Ballycamus. The best of the fishing begins at "Agents Flats", about 2 kms downstream of Holycross and extends for 6 kms to Ballycamus Forde. "Agents Flats" to "Two-Forde Bridges" offer good wet and dry fly fishing with trout to 2 lbs. From the confluence of the Clodiagh River to Ballycamus Forde is an excellent dry fly section and holds a good stock of trout.
The River Drish is a clear, slow-flowing lowland stream that joins the River Suir just over 1½ kms south east of Thurles. The middle and lower sections from Athlummon down to the confluence with the Suir hold good stocks of trout up to 3 lbs. The best fishing periods are from April to mid-June. Upstream from Drish Bridge becomes weeded in mid-summer but downstream is usually fishable throughout the season and can provide dry fly fishing on summer evenings.
The season runs from 17th March to 30th September inclusive.
