Following a competitive tender process O’Connor Sutton Cronin (OCSC) were appointed as the consulting engineers to undertake a range of technical assessments and prepare an options report for fish passage improvement works at Annacotty Weir in Limerick. This options report will consider all environmental and engineering circumstances that are present at the site. OCSC have undertaken a number of assessments over the last few months, with a view to preparing an options report in early 2024. The options report will be based on several environmental and technical surveys, using a recognised decision matrix, together with a stakeholder decision matrix. The options report will be presented to the public for consideration by all stakeholders with a view to bringing a proposal forward for planning permission.
In advance of any permanent works taking place, Inland Fisheries Ireland (IFI) had planned to carry out temporary works during the summer with the aim of improving passage for eels and lampreys. However, high water levels hampered attempts to install these measures – water levels remained too high since IFI received the materials. The proposed temporary works follows advice from specialists within IFI’s research division which suggests the installation of bristle mats and lamprey tiles will help facilitate eel and lamprey passage. IFI plans to install these measures when water levels are at a suitably low level to allow safe access to the weir to install the materials.
