This small body of fresh water at the location to which the Deputy refers periodically silts up. Approximately every seven to eight years the navigation channel needs to be dredged and deepened to original levels. This maintains access at low water levels. As with any proposed works that are within the National Park in question, they are also with a European site of nature conservation (SAC) and are subject to screening for appropriate assessment in relation to their potential impact on any of the qualifying interests of the site.
I understand that NPWS regional staff have completed the screening process as well as a tendering process to secure a suitably qualified contractor to carry out these works. They are currently considering all the requirements of the screening process prior to starting any works. A licence from the Irish Fisheries Board is also a requirement, and an application is pending.
It is likely that these works will be completed as planned in the coming weeks.
