There have been some delays in the work to clear the scour valve. This was originally scheduled for July, was then postponed until August, and we now understand will take place sometime in September. We will keep everyone informed when the work is due to start. In the meantime, the reservoir continues to refill, and it is quite encouraging to see how quickly this has happened.
Over the summer, members of the RAG Committee have been visiting other sites that run sailing and fishing operations such as Llandegfedd reservoir near Pontypool, where Dwr Cymru / Welsh Water have built a new visitor and sailing centre; and Lliw reservoir, just north of Swansea, where local residents have set up a Community Trust to run the recreational facilities there.
We are hoping to send round a newsletter to RAG members in September, with further details of these schemes and other developments.

|Rising water level in Llanishen Reservoir|
Many local residents have noticed that the water level in Llanishen reservoir is gradually rising and have been asking how this can happen if the scour valve that drains the reservoir is still open. We recently contacted Dwr Cymru Welsh Water for an explanation, as they now have an agreement with Celsa to undertake monitoring and the day-to-day maintenance of the reservoir.
We have been told that the scour valve has been closed for the past 12 months and this is why water levels in the reservoir have increased. Welsh Water have asked for the scour valve to remain closed as the company needs to carry out particular maintenance work which includes removing some silt which has built up around the scour. This will be done sometime in the summer of 2015. It is anticipated that the scour valve will then be re-opened again.
