One hundred years ago the first sod was cut at the Silent Valley in County Down, to create the huge reservoir that eventually suppled water to the city of Belfast. It was a mammoth undertaking, which stretched the technology of the time. Gary Presho, NI Water’s water supply manager, and Anna Killen, the education officer explained how it all happened. Anna told Anne Marie McAleese why they were keen that schoolchildren were involved in the celebrations. And in County Derry a very special book, described as the bible for anglers in the north west, has been republished by local anglers. Fly Fishing for Trout and Salmon on the River Faughan is so rare that first editions can change hands for more than a thousand pounds. It was written by E.C or "Clarkie" Heaney, also known as Black Spider. Helen Mark met keen fisherman, Gerry Quinn, on the banks of the river to hear more about this angling magnum opus. Presented by Anne Marie McAleese.
