About this water

Brown trout
OS Grid Ref: SH 66389 47092
Latitude: 53.00443199987
Longitude: -3.99261586279

Any method is permitted.
The lake is at around 1,720 feet above sea level and 1 and a half hours walk from Tanygrisiau.

At 7 acres, Cwm Corsiog is an excellent early season lake until the weed grows in mid summer making some of it unfishable. It can still be fished successfully after then by changing to floating lines and dry flies, casting over the weed into clear patches.

The trout are numerous and very free rising, they run up to 3/4lb.
