Watershed Monitoring

The LSRCA is continually involved in various kinds of monitoring activities: water quality testing, animal population surveys, groundwater and stream flow monitoring, and lake and river level monitoring.

The information collected from these activities is used to track trends and predict future changes in the environment, like climate change. The information also alerts us to identify and locate the origins of problems.

The LSRCA operates:

  • Twelve ambient water quality monitoring sites detecting nutrient levels, metals, and general water quality, in partnership with the Ministry of the Environment.
  • Six water quantity stations, and another seven in partnership with the Ministry of Natural Resources.
  • Fourteen groundwater monitoring wells, in partnership with the Ministry of the Environment.
  • Six year-round precipitation gauges.
  • One evaporation pan, in partnership with Natural Resources Canada.
  • Twenty fish population monitoring locations.
  • Twenty Benthic Invertebrate monitoring locations.
