Grand Canal: The heart of Dublin City

For those of you who don't know about the Grand Canal and how much a part of Dublin it is, here are two great videos showing just how much a part of the City it is.

Swan mortalities on the Grand Canal

Seventeen dead swans were recovered from the Grand Canal in Dublin  between the 9th and 10th of March and a further ten seriously ill swans removed from between Portobello Harbour and the Suir Road Bridge. Initially it was thought this was due to Avian flu but this has subsequently been ruled out with experts now believing the cause to be a bacterial disease, most likely botulism. However, what is of concern is that this is close to the area currently being dredged and that dead fish have also been reported. The dead animals are undergoing tests at the State Laboratory although confirmation of the cause of death is not expected until the end of the month. Swans are particularly vulnerable to sudden changes in water quality and contaminated food resources, especially in urban locations on canals where they do not find it easy to move from one enclosed stretch to another. In my opinion a possible link to the dredging activity does need to be positively ruled out so that this important maintenance work can continue in future years with any necessary safeguards in place.

Dredging continues along the Grand Canal in Dublin

Waterways Ireland is continuing to dredge sections of the Grand Canal in the City Centre to keep it navigable for large boats. For those of you who travel on the Luas you will notice that sections are currently devoid of water as sediment and rubbish are cleared. This means the section between Lock C4 (Baggot Street) and Lock 1 (Suir Road) will not be navigatable. This work will be completed by April. Although the National Parks and Wildlife Service are advising the company on how to minimize damage to the wildlife of the canal, much of the freshwater flora and fauna will simply be removed or destroyed by the work. The Canal is a unique reservoir for Irish freshwater biodiversity but the periodic dredging work is unavoidable to prevent the canal from completely silting up. Further details.
