My travels around the UK by car for three weeks with my son. June/July 2019 Wales.
Day eight .. Stopping at the Elan Valley Reservoirs before making our way to Aberystwyth for the night.
Radnorshire map in the form of standing stones near the Elan Valley Visitor Centre
An explanatory board at the far end shows that each stone represents a population centre of the former county of Radnorshire, now part of Powys. The stones are set at the correct scale distances apart, and the perimeter, part of which can be seen here as a lighter colour in the grass, is in the shape of Radnorshire.
This was a Millennium Project. The 2000 Radnorshire population of 24,917 shown on the board is little different from its population of 24,651 recorded at the 1831 Census. The largest population centre is Llandrindod Wells (5,024 at the 2001 census).
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.
Water from the reservoirs is carried by gravity to Frankley Reservoir in Birmingham via the Elan aqueduct. Pumping is not required because the network drops 52 metres (171 ft) along its 73 miles (117 km) length from its source to Frankley. A gradient of 1:2300 maintains a flow of less than 2 miles per hour (3.2 km/h); water takes two and a half to three days to reach Birmingham. The aqueduct, which was started in 1896 and opened in 1906, crosses several valleys and features numerous brick tunnels, pipelines, and valve houses.
Work to build the Elan Valley reservoirs was undertaken because the rapid growth of the industrial city of Birmingham in the late 19th century had led to a lack of available clean water. Numerous outbreaks of disease prompted Birmingham City Council to petition the British government which passed the Birmingham Corporation Water Act in 1892. It allowed the Corporation to acquire by compulsory purchase all the land within the water catchment area of the Elan Valleys. Thousands of navvies and their families lived in the purpose-built Elan Village during the construction of the first four dams at the turn of the 20th century. In 1952, the Claerwen dam was opened by Elizabeth II in one of her first official engagements as monarch.
Drinking water from the Elan Valley is noted for being exceptionally soft, contrasting with water from local supplies in the West Midlands, not served by the Elan aqueduct, which are noted for hardness.

Usinsk is the center for the production of oil and gas in the Komi Republic. Three quarters of all the oil produced in the republic comes from the fields in the territory around Usinsk. In 1994, Russia’s largest oil spill occurred in the Usinsk region when an estimated 100,000 tons flowed from an aging pipeline.
