Eglwys Nunydd is a 260-acre lowland reservoir in Margam near Port Talbot, Wales. The reservoir provides water for the nearby steelworks and is a Site of Special Scientific Interest due to its fertile environment and diverse birdlife. Angling at the reservoir is controlled by the Tata Game Angling Association, a friendly and very welcoming club of around 100 members that celebrated its 50th year in 2016. The club welcomes anglers of all abilities and is keen to promote fly fishing to all.

The club stocks the reservoir with about 4,500 hard fighting rainbow trout averaging near 3lb, and with each stocking including some much larger fish.

Day tickets are available online with the Fishing Passport.
