These lakes on the upper Rheidol at the foot of Pumlummon itself are part of the Rheidol electric power scheme: they provide an interesting contrast in angling experience.

The 32 acre Dinas Reservoir which is the the smaller of the two – is popular and regularly stocked with rainbow and brown trout. The quality of its fish has been described as second to none by Moc Morgan, angling correspondent for the the Trout and Salmon magazine.

Nantymoch is the much larger and wilder lake (680acres), provides a huge expanse of wild brown trout fishing – typically small but worthy opponents. For the angler who wants to get away from it all Nantymoch is the place to visit. Both lakes are bank fishing only. Nantymoch is fly only but on Dinas spinning and worming are also allowed.
