I am advised that the Lough Beag stream forms part of the Corrib catchment drainage programme which is managed by the Office of Public Works (OPW). I understand that this channel is monitored by OPW and also that the lower section of the stream is scheduled for drainage maintenance in 2015. I am further advised, as regards the concerns now expressed, that water levels in the Corrib catchment reached exceptionally high levels over the Winter / Spring of 2013/14 – and remained at that level due to high rainfall well through Spring 2014.
The in-stream structure upgrades were carried out by Inland Fisheries Ireland (IFI) in partnership with OPW.
I understand that the Lough Beag stream was identified by IFI as a channel with potential for improvement works aimed at increasing its productivity for wild brown trout production. This was part of the ongoing development programme of the Corrib catchment in conjunction with the Corrib Angling Federation and local angling clubs. I am advised that the works commenced in 2012 and were completed in 2013. These works focussed on upgrading existing in-stream structures with a view to improving fish habitat together with the introduction of gravel for trout to spawn in.
I understand that the work included rock deflectors and pools with stones for trout habitat designed to retain water only during low flow periods and to flood out in higher water. I am advised that the structures have no impact when the stream is in flood as the water drowns out the structures. This channel is indexed in the OPW drainage programme as C25 and as the stream is at lake (Lough Corrib) level it will consequently be directly influenced by the water levels in the Lake. I am advised that In-stream structures in this case are incidental in terms of flooding in times of high lake level.
It is understood that the lands in question are in the ownership of an individual who had given consent for the works to take place. I am also advised that during the programme of works the landowner regularly visited the site and engaged with staff on the programme.
In July, 2014 IFI were made aware of certain concerns in relation to the works – and an on-site meeting of relevant parties was arranged. IFI are keen to ensure that the responsibilities of the state (OPW and IFI) and the concerns of all involved including local landowners are addressed. I have asked IFI to liaise with the OPW to ascertain if the concerns raised by the Deputy are manifest in any deterioration in the ability of the river to discharge as designed.
