The James Bay River Monitoring Network

This website is designed primarily to allow the community to visualize river water discharge and temperature data that are generated by the James Bay River Monitoring Network. In addition to the 9 stations that were deployed by Niskamoon in 2018, the site shows data from 5 existing hydrometric stations located in the Eastern James Bay that have been operated by Hydro Québec. The data is not real time since they are updated weekly.

Click here to learn how to visualize the data!
  1. Check the location of all the hydrometric stations available using the map displayed on the left. Zoom in and out to explore their location across the region and click on the colored dots to check the name of the river in which they are located.

  2. To visualize the data of each station, click on the river name displayed in the top horizontal bar.

  3. Two plots will be displayed, the top plot shows average discharge per day (measured as water volume flowing per second), the bottom shows the average water temperature (in degrees Celsius) per day.

  4. Below each plot there is a window where you can choose the time interval for which the data are displayed. Here you can click and move the two white vertical bars on the right and on the left to select a particular interval of time that you wish to observe.

  5. Pass the mouse cursor over the graph lines to visualize the discharge value and its corresponding date, which will be displayed in a label box colored with the same colour as graph lines.
