Many thanks to Dolau Afon Holidays  for facilitating this camera's location. This camera is capitally funded by Aberystwyth University. The River Ystwyth, known as the "winding river," stretches for a length of 20.5 miles. Its extensive catchment area covers 75 square miles. The river finds its source in several streams, including the Afon Diliw, located on the western slopes of Plynlimon, bordering Ceredigion and Powys in the Cambrian Mountains. Flowing westwards, the Ystwyth eventually merges with the River Rheidol and drains into the estuary at Aberystwyth, ultimately reaching Cardigan Bay. The Ystwyth valley, encompassing villages such as Ysbyty Ystwyth, Cwm Ystwyth, Pont-rhyd-y-groes, Llanilar, and Llanfarian, remains sparsely populated. However, in previous centuries, the valley was densely inhabited due to its abundant mineral resources. Mining activities for silver, lead, and zinc have been prevalent in the valley since Roman times, reaching their peak in the 18th century. Notably, Cwm Ystwyth Mine was the largest of the numerous mines in the area. Unfortunately, the miners in Cwm Ystwyth experienced a significantly reduced average lifespan of 32 years, primarily due to acute lead poisoning. Presently, there is no active metal mining taking place in the Ystwyth valley.Hafod Uchtryd, a mansion constructed by Thomas Johnes in 1783, with some parts designed by John Nash, held prominence in the area. The mansion's landscaped gardens were created by removing sections of hills to create picturesque views. Roadways, bridges, and an extensive planting of trees were also part of the landscape design. The result was a renowned scenery that attracted numerous visitors, including Samuel Taylor Coleridge, who is believed to have been inspired by the landscape in his poem "Kubla Khan." Although the mansion was demolished in 1955, the landscape remains preserved to this day.Despite the passage of time, the River Ystwyth still carries elevated levels of lead, zinc, and silver in its water, primarily due to seepage from abandoned mine tailings and discharges from mine adits. To address this pollution, Natural Resources Wales has implemented an innovative technique at the Frongoch mine near Pont-rhyd-y-groes. Water from the mine is diverted via a leat to a wetland area, where the vegetation facilitates biological processes that immobilize a significant portion of the pollutants. A similar approach is being employed at the Cwm Rheidol mine near Aberystwyth. These remedial measures are of utmost importance as the area supports a diverse range of wildlife and attracts anglers and tourists. Additionally, a webcam has been installed to monitor the movement of large woody debris in specific areas, including the Capel Bangor road bridge on the River Rheidol and the downstream section of the Grogwynion reach of the Ystwyth. The primary focus of this monitoring is to assess potential risks related to flooding.
