Afon Gwyrfai

Last updated

The Afon Gwyrfai is a short river in Gwynedd, Wales. For half of its length it flows through Snowdonia National Park. Exiting Llyn y Gader it flows north through the small village of Rhyd-ddu to enter the southeastern end of Llyn Cwellyn. Downstream of the lake it flows northwest past Betws Garmon, leaving the national park and continues to the southern edge of Waunfawr. It then turns slightly west to flow on to Bontnewydd beyond which it turns slightly south to enter Foryd Bay (Y Foryd). The tidal channel within the bay flows north into the western end of the Menai Strait. Principal tributary streams include the Afon Treweunydd which contributes water from the reservoir of Llyn Ffynnon-y-gwas and from the lakes of Llyn Glas, Llyn Coch and Llyn Nadroedd in Cwm Clogwyn immediately west of the summit of Snowdon. The tidal channel of the Gwyrfai within Foryd Bay also accepts the flow of the left bank tributaries, the Afon Foryd, Afon Rhyd and Afon Carrog. The river is shadowed by the line of the Welsh Highland Railway for much of its length, and by which it is crossed four times. [1]

The name may signify the '(river of) curved places', referencing its meandering course. [2]

The Afon Ysgethin is a short river in Gwynedd, Wales. Flowing entirely within Snowdonia National Park it rises beneath the peaks of Y Llethr and Diffwys within the Rhinogs mountain range and runs in a generally ESE direction towards Cardigan Bay. Headwater streams flow into Llyn Bodlyn reservoir and a small upper lake, Llyn Dulyn. The river emerging from the reservoir dam is crossed by an historic track at Pont Scethin. This old stone arch bridge was used historically by packhorses and drovers moving between Harlech and London. A further 3km downstream it enters a narrower wooded valley and is crossed by Pont Fadog. There are two further crossings at the village of Tal-y-bont; by the A496 road and by the Cambrian Coast railway. After another 1km it enters the sea.

The Afon Soch is a short river on the Llŷn peninsula, Gwynedd, Wales. It arises to the north of the village of Sarn Meyllteyrn, through which it then flows, turning southeast towards Botwnnog. Beyond Botwnnog it is joined by its main left-bank tributary, the Afon Horon, which rises to the east of Carn Fadryn. Their combined flow approaches the coast at Porth Neigwl but instead the river turns sharply northwards at Llanengan and curves around east to Abersoch where it enters the sea. A short section of the Soch valley is followed by the Wales Coast Path where it takes a route inland of Porth Neigwl. Both the Soch and the Horon are misfit streams within valleys that were formed by glacial meltwater. The river name is reckoned to be of Irish origin, the old Irish word 'socc' meaning a sow. There are a number of other Irish names in Llŷn.

The Afon Ffraw is a short river on the Isle of Anglesey, Wales. It arises at Llyn Coron and flows southwest for two miles along the northwestern margin of Twyn Aberffraw via the village of Aberffraw to Aberffraw Bay on the island's west coast. The river is tidal to a point just northeast of Aberffraw and is accompanied by the Wales Coast Path and Isle of Anglesey Coastal Path. Llyn Coron is fed by the Afon Gwna which rises near to Llangefni in the centre of Anglesey. The flow of the Ffraw is bolstered by the left-bank tributary, the Afon Frechwen and a larger, though unnamed right-bank tributary which rises near Gwalchmai. Pont Aberffraw is a bridge spanning the river constructed as a single stone arch in 1731. When the A4080 main coastal road was diverted onto a new line, the old bridge closed to traffic.

The Afon Erch is a short river on the Llŷn peninsula, Gwynedd, Wales. It arises near the village of Llanaelhaearn, flowing south and southwest towards the hamlet of Llwyndyrys where it turns abruptly eastwards and curves around to the south, passing to the east of Y Ffor at Rhyd-y-gwystl. It continues towarin a SSW direction towards Abererch where despite the village name, it does not enter the sea but flows west parallel to the coast for 1 mile to Pwllheli. The Afon Rhyd-hir joins the Afon Erch within the tidal basin of Pwllheli Harbour. Its headwaters gather to the south of Llithfaen and flow south past Llannor to approach Pwllheli from the west. It is joined by the Afon Penrhos immediately west of the town, having originated around the extensive bog of Cors Geirch, a national nature reserve. Parts of the courses of each of these rivers occupy valleys that were formed by glacial meltwater. The uppermost Penrhos is a misfit stream within its valley.
