The Elan Valley Reservoirs are a chain of man-made lakes created from damming the Elan and Claerwen rivers within the Elan Valley in Mid Wales. The reservoirs, which were built by the Birmingham Corporation Water Department, provide clean drinking water for Birmingham in the West Midlands of England. The five lakes are known as the Claerwen, Craig-goch, Pen-y-garreg, Garreg-ddu, and Caban-coch.
The Cambrian Mountains are a series of mountain ranges in Wales. The term Cambrian Mountains used to apply to most of the upland of Wales, and comes from the country's Latin name Cambria. Since the 1950s, its application has become increasingly localised to the geographically homogeneous Mid Wales uplands, known in Welsh as Elenydd, which extend from Plynlimon (Pumlumon) to Radnor Forest in the east and Mynydd Mallaen to the south. This barren and sparsely populated 'wilderness' has been referred to as the Desert of Wales. The area includes the sources of the River Severn and River Wye and was unsuccessfully proposed as a national park in the 1960s and 1970s. The highest point of the range is Plynlimon, at 2,467 feet (752 m).
The River Teifi in Wales forms the boundary for most of its length between the counties of Ceredigion and Carmarthenshire, and for the final 3 miles (4.8 km) of its total length of 76 miles (122 km), the boundary between Ceredigion and Pembrokeshire. Its estuary is northwest of Cardigan, known in Welsh as Aberteifi, meaning 'mouth of the Teifi'. Teifi has formerly been anglicised as "Tivy".
The Desert of Wales, or Green Desert of Wales, is an archaic term for an area in central Wales, so called for its lack of roads and towns, and its inaccessibility. The term was coined by English travel writers in the nineteenth century and has no equivalent in the Welsh language. The area corresponds roughly to the upland area called Elenydd in Welsh.

The Afon Dulas, or North Dulas, is a river forming the border between Merionethshire/Gwynedd and Montgomeryshire/Powys in Wales. Another river called Afon Dulas joins the Dyfi from the south, upstream of its confluence with the North Dulas: locally this is referred to as the South Dulas.

It then takes a twisting route south via the villages of Llanbister, Llanddewi Ystradenny and Penybont before turning southwest, then doubling back northwards towards Crossgates. From here it resumes a southwesterly course, flowing past Llandrindod Wells and the site of Cefnllys Castle to a confluence with the Wye, 1 mile to the south of Newbridge-on-Wye.
