You’ve probably all noticed that we’re closing down our Lake Vyrnwy and Ynys Hir facebook pages and we have set up a new ‘RSPB Mid Wales’ page.
We understand that some of you will be disappointed to see these pages go.
Unfortunately Facebook doesn’t allow us to change the name of the page unless you have less than 200 fans. Therefore, we’ve set up some new pages
Please feel free to add your photos to our new pages – we’d love to see them on there! Unfortunately, once this page is closed, there will be no way to access photos on this page again.
Our new structure will allow you to continue to receive all the latest news from Ynys-hir and Lake Vyrnwy. It will also allow us to share news of other interesting stuff happening in your wider area.
We don’t want you to miss out on news from your favourite places, so this new page will enable us to keep you fully up-to-date without you having to follow lots of different RSPB pages.
The RSPB Lake Vyrnwy and RSPB Ynys Hir pages will be closed within two months – please become a fan of RSPB Mid Wales before then.
Thanks again for all your support and for following us for this long, please continue to follow us on our new page, we look forward to seeing you there!

Efallai y byddwch yn siomedig efo’r newidiadau yma, felly dyma rhai cwestiynau (wedi eu hateb) a bydd yn medru esbonio beth sy’n digwydd.
Yn anffodus, dydy Facebook ddim yn caniatáu i ni newid enw’r dudalen os nad oes gennych lai na 200 o ddilynwyr. Felly, rydym wedi sefydlu tudalennau newydd.
Mae croeso i chi ychwanegu eich ffotograffau at ein tudalennau newydd – byddem yn falch iawn o’u gweld yno! Yn anffodus, unwaith y bydd y dudalen hon wedi ei chau, ni fydd ffordd o gael gafael ar y ffotograffau ar y dudalen hon eto.
Bydd ein strwythur newydd yn eich galluogi i barhau i dderbyn y newyddion diweddaraf am eich hoff warchodfa. Bydd hefyd yn caniatáu i ni rannu newyddion am bethau cyffrous eraill sy’n digwydd yn eich ardal chi.
Dydyn ni ddim yn dymuno i chi golli’r newyddion am eich hoff leoliadau. Bydd y strwythur hwn yn ein galluogi i anfon y newyddion diweddaraf i chi heb i chi orfod dilyn llawer o wahanol dudalennau’r RSPB.
Bydd RSPB Ynys-hir a RSPB Lake Vyrnwy yn cael eu cau o fewn dau fis -dilynwch ein tudalen newydd RSPB Mid Wales cyn hynny.

Autumn is a stunning season and Lake Vyrnwy has been looking spectacular over the past few weeks. The deep chestnut colour of the beech leaves reflecting on the still waters of the lake, combined with beautiful light has made it a photographer’s dream. A lot of our time recently has been taken up with nestboxes, 500 of them in fact- cleaning them, maintaining them, updating the maps and using a GPS to get a grid reference for each box. All of the work we have been doing is designed to reduce the amount of time spent doing the same job next year and to help with bird ringing in the spring and summer.
Gethin and I have successfully passed our chainsaw tests. Gethin had a refresher for medium and large trees and I now have a license for small trees. It was a great week of training and our instructor Alun Jones was fantastic. I had previously never picked up a chainsaw and Alun was extremely patient and clear. We undertook this training so we can begin clearing a few of the self-seeded conifers from the upland areas of the reserve. We also have a patch of land in some local forestry, which we manage specifically for Black Grouse and this means clearing away some of the conifers in the area to create a more mixed habitat with areas to feed that has adequate cover close by. We have lots planned for the coming weeks including doing maintenance on parts of the hides and gathering and processing heather seed.
The Vyrnwy dam is an impressive structure, said to have been the largest civil engineering project in the world at the time of its construction - though I've never known how we know that. From the foundation at bedrock level to the overflow lip, it measures 144 feet in height. You can get an idea of the scale by comparing it with the (much earlier - 1815) Pontcysyllte aqueduct, Telford's "stream in the sky". Our dam is 20 feet higher, not even allowing for the arches and the towers. 127 feet thick at the base, holding back 13,000 million gallons of water, it was designed with a life expectancy of 100 years - making it now 25 years past its sell-by date!
The arrival of clean fresh water made a huge difference to Liverpool in the early 1890s. The expanding city depended at the time on the inadequate Rivington Water Works, opened in 1857, and a leaky system of outdated water mains. Chiefly responsible for bringing in the Vyrnwy water was one remarkable man, employed by Liverpool Corporation from 1871 to 1890 and now largely forgotten. He died in 1909, nine months before the Prince of Wales came to declare the Vyrnwy works completed, and is buried at Addington, near Croydon. At Llanwddyn, he is commemorated by two windows and a brass monument in the church, and by his name, George Frederick Deacon, listed in the smallest letters at the very bottom of the bronze plate put up at the opening ceremony. You can see it at the north end of the dam.
The Lake Vyrnwy waterworks project was far from being George Frederick Deacon's only claim to fame. As a young man, he played a significant part in the laying of the second transatlantic cable, beginning a life-long friendship with Lord Kelvin, whose student at Glasgow he had been. Later, in Liverpool, he made himself an expert on the Mersey estuary, and then, working for the Corporation of Liverpool, he constructed about 70 miles of new and refurbished sewers. He was responsible for the introduction of solid street paving in Liverpool, for the laying of the tramway rails in 1877, and for a system of refuse disposal using "destructors" and hopper barges to carry refuse out to sea. In 1873, having designed a successful metering system to monitor water wastage through leaky mains, he was asked to recommend a scheme for a new water supply for the city, and this resulted in the Vyrnwy works, to which he devoted himself as designer, engineer, and project manager until its completion.
Rewards and recognition were plentiful - the George Stephenson Medal, Telford medals, an honorary doctorate of Glasgow University, among others - and later, working for himself as a Consulting Engineer, George Frederick Deacon advised the Canadian authorities on water management at Niagara Falls. In Western Australia he advised on water supply at Coolgardie, in the gold fields. At the time of his death, aged 66, he was involved in the planning and construction of the Alwen dam on Hiraethog for the Birkenhead corporation, where his name can be seen today on another bronze tablet.
It seems a shame to have forgotten him. Next time you cross the dam, look out for his name. Better still, go up to the church and admire the windows. George Frederick Deacon made a big difference to many people's lives.
