Llyn Clywedog was the Tallest in the British Isle built purposely to control the level of water to help prevent any future flooding from the source of the River Seven. By Building this absolutely incredible huge 6 mile long dam, one that was the tallest in the British isles, which is amazingly huge in actual size all around! This mammoth body of water is solely to take the huge pressure off the constant mass of floods which would fill up and submerge the surrounding valleys! At the foot of the dam there is a remains of a old lead mine! All structures you can see standing still today. HIGHLY RECOMMEND

December 8, 2022, Bryn y Fan Summit

Bryn y Fan is a prominent summit in mid Wales standing at 482m above the Llyn Clywedog reservoir. There is a nice trig point and great views. It's a bit of an outlier and you're unlikely to see many people on your walk.

Llyn Clywedog is a man made reservoir built between 1965 and 1967 to help regulate the flow of water in the Severn. It's also used to reduce the risk of flooding up and downstream. Amusing comparison but the lake holds the equivalent of 264 billion glasses of water or 550 million baths. The area around the lake is a well kept habitat for many birds and animals including recent visits from ospreys. The lake is well stocked with trout and a popular fishing destination.
