Notices to Skippers contain dynamic information on current and future changes in the traffic status on inland waterways. The messages are divided into four categories: fairway and traffic related messages (FTM), water level related messages (WRM), weather related messages (WERM) and ice messages (ICEM). The datasets on the EuRIS API also contain international datasets from partner countries that implement selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. This dataset includes data from the dataset "Other physical limitations on waterways, Temporary obstructions in the fairway, Restrictions caused by floods and ice" and "Short term changes of lock and bridge operating times" according to Annex No. 6 of Commission Implementing Regulation (EU) 2023/138 establishing a list of specific high-value datasets and measures for their publication and re-use.
