Note of Data Sources:
  1. The observed discharge and water level data are provided by the Water Survey of Canada (Disclaimer for Hydrometric Information and Terms and conditions), and represent the most current reading between midnight and 8AM on the current date.
  2. Return Periods are expressed in years and reflect the discharge rate associated with the statistical probability of the annual maximum discharge of the historical record for a given station. Data shown on the map indicate the forecast range of discharge at a site for this forecast period.

Users should use the information on this map with caution and do so at their own risk.

  Modeling Uncertainty and Disclaimer: This forecast is derived from the COFFEE Model, a hydrological model using third-party data as inputs. The model has two categories of uncertainty or forecast errors, systematic errors from the model’s intrinsic limitations and random errors inherited from the input data. Therefore, it can be expected that the model forecasts are different from the observations. It is also possible that the actual flow is higher than the forecast upper bound or lower than the forecast lower bound. Users of this forecast must accept all responsibility for their use and interpretation. Please follow the links below for more information:
