The Craig Goch Dam, often called the Top dam, is a masonry dam in the Elan Valley of Wales and creates the upper-most of the Elan Valley Reservoirs. Construction on the dam began in 1897, and it was completed in 1904. The primary purpose of the dam and the other reservoirs is to supply Birmingham with water.{{cite web|title=CRAIG GOCH DAM, ELAN VALLEY WATER SCHEME|url=http://www.coflein.gov.uk/en/site/32521/details/CRAIG+GOCH+DAM,+ELAN+VALLEY+WATER+SCHEME/|publisher=Royal Commission|accessdate=17 March 2011}}{{cite web|title=The Elan Valley dams - Craig Goch dam|url=http://history.powys.org.uk/history/rhayader/craig.html|publisher=Powys Digital History Project|accessdate=17 March 2011}} In 1997, a 480 kW hydroelectric generator began operation at the dam.{{cite web|title=Dams & Reservoirs|url=http://www.elanvalley.org.uk/dams-reservoirs/|publisher=Elan Valley|accessdate=19 March 2011|url-status=dead|archiveurl=https://web.archive.org/web/20110324231554/http://www.elanvalley.org.uk/dams-reservoirs/|archivedate=24 March 2011}}{{cite web|title=Elan Valley Hydro Scheme|url=http://www.esru.strath.ac.uk/EandE/Web_sites/01-02/RE_info/hydrocase.htm#The%20four%20dams%20involved|publisher=University of Strathclyde|accessdate=19 March 2011|archive-date=23 March 2018|archive-url=https://web.archive.org/web/20180323180702/http://www.esru.strath.ac.uk/EandE/Web_sites/01-02/RE_info/hydrocase.htm#The%20four%20dams%20involved|url-status=dead}}

Potential river transfer scheme

The Craig Goch reservoir had been identified in the 1970s and in the 1990s as a potential source of water for the south-east of England.{{cite web|url=https://www.newscientist.com/article/mg15120410-600-thames-scheme-threatens-river-life/|title=Thames scheme threatens river life|date=3 August 1996|access-date=3 September 2020|publisher=New Scientist}} The latest project envisaged raising the existing dam, adding a secondary dam at the head of the River Ystwyth valley and piping water from the high head generated into the River Severn and subsequently transferring it by pipeline aqueduct to the head-waters of the River Thames in the Cotswolds.

Media appearances

Craig Goch Dam was featured prominently in Episode 3 Series 3 of BBC Wales drama series Hinterland, broadcast 2017.
