Map of 7-Day Average Streamflow


This map includes the following 4 layers: (1) 7-Day Average Streamflow - All (current view); (2) 7-Day Average Streamflow - 80% and Lower; (3) Drought Level indicators - All; and, (4) Drought Level indicators - Dry. (This page is updated on a weekly basis.)

Instruction: 1. To select a different layer or show the legend, click the layer or legend icon in the top-left corner. 2. Click on a station to show station information and % of historical median 7-day average streamflow and drought level indicator. 3. Click "More info" on the pop-up information window to view the hydrograph of 7-day average streamflow for the station.

Note of Data Sources:

  1. The river discharges and water levels are from Water Survey of Canada (WSC) (Disclaimer for Hydrometric Information and Terms and conditions) and provisonal and represent the readings at the update time displayed on the map and data layers.
  2. The percent of median flows and the drought levels are calculated based on the historical records and the provisional data from WSC for a given station. Data shown on the map and data layers indicate the current range of discharges or water level at a station for the update 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 percent of median flows and the drought levels presented on this map are preliminary and based on limited data and subject to change. They should be considered as reference values only. They should not be used for design or other purposes. Users of this data must accept all responsibility for the use and interpretation.
