Map of Current Streamflow Conditions for All Real-time Stations in BC
This map includes the following 4 layers: (1) Discharge/Water Level Return Period - All Stations (current view); (2) Discharge/Water Level Return Period =2Y and Up; (3) % of Mean Annual Discharge - All Stations; and, (4) % of Mean Annual Discharge below 50%.
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 current reading, the return period, or % of mean annual discharge (MAD). 3. Click "More info" on the pop-up information window to view the WSC's real-time hydrometric data or B.C. Real-time Water Data for the station.

Note of Data Sources:
Users should use the information on this map with caution and do so at their own risk.
The data used on the map are from the Water Survey of Canada (WSC) real-time hydrometric data, B.C. Real-time Water Data, and USGS Real-time Water Data as they are. The data are collected by automated monitors at numerous remote locations and are unverified. The data are provisional or 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 periods for flows (discharges and/or water levels) presented on this map are preliminary and are often based on limited data. They should be considered as reference values only, which are used to show the relative magnitudes of the current readings. They should not be used for design or other purposes under any circumstances. Users of this data must accept all responsibility for the use and interpretation.
