Members of the Charts Special Interest Group (CSIG) are working together to deliver charts for the rivers, lakes and canals of Ireland with the aim of making the waterways safer and more enjoyable for everyone.  Achieving this goal involves carrying out depth surveys, analysing data, adding location knowledge and then producing electronic charts from the resulting information.

The CSIG is a cooperative of members from all branches of the Inland Waterways Association of Ireland (IWAI).  The CSIG also collaborates with others in Ireland who are interested in what we are doing, including archaeologists, historians, rescue services, sub-aqua groups, leisure users and communities along the waterways.

Work began with one small team in 2011 and has since expanded to include several teams surveying different waterways or gathering information. The diverse skills required are passed on to new members at training and one-to-one practical sessions. Finance to underwrite this endeavour comes from our members and from several branches of the IWAI.

This year, 2024, we commence our 13th year of what we envisioned back at the start, as a ten-year programme.   Over the past few years, we have released Beta versions of the charts to our IWAI Test Group.  The charts now cover the Shannon, the Ernes, Lough Neagh, the Newry Ship Canal, the Rivers Barrow, Nore and Suir and the Grand Canal and Royal Canal.
