Description: Canadian tides and water level data. Station information, digital data inventory of observed water level data available for download. As Canada's national data center, the historical tide and water level data archive presently holds over 500 million records with the earliest dating back before the turn of the century. Over 2 million new observations, reported from the CHS permanent gauging network, are added on a daily and monthly basis. Data are also exchanged annually with Environment Canada. The predictions web service offers water level predictions for over 800 coastal locations all over Canada. The observations web service gives access to real-time water level observations made by the network of permanent water level recorders on the St. Lawrence between Montreal and the Magdalen Islands. Other network stations across the country will be added over time. When available, recorded observation data for the past 12 months can be accessed. The forecasting and interpolation web service (commonly called SPINE) is a system used to forecast water levels at a specific time and position up to 30 days in advance for the St. Lawrence ship channel between the Port of Montreal and Saint-Joseph-de-la-Rive. This system is based, in part, on water level forecasts derived from a hydrodynamic model that takes various weather conditions into account and, in part, on real-time observations made by the network of permanent water level recorders. To increase their accuracy, digital model forecasts are adjusted according to water level observations for the entire area. A precision matrix is also provided for forecast data.
