Note of Data Sources:
1. The river discharge and water level data are provided by the Water Survey of Canada (Environment Canada), and represent the most current reading between midnight and 8AM on the current date.
2. Return Periods are expressed in years and reflect the expected discharge rate associated with the statistical probability of a given discharge occurring in any year based on the historical record for a given station. More information on Return Periods. Data shown on the map indicate the expected range of discharge conditions at a site for the day.

Disclaimer:
Users should use the information on this map with caution and do so at their own risk. The data are collected in near-real-time by automated monitors at numerous remote locations and are unverified. The data are preliminary, and may be changed upon subsequent review. Some data may be wrong. It is not uncommon for individual water level recorders to give false readings, due to local conditions. The return period estimates presented on this map are preliminary and are often based on limited data. They should be considered as reference values only, by which to evaluate the current readings. They should not be used for design or other purposes. Users of this data must accept all responsibility for the use and interpretation.
