Watershed Monitoring Programs

Snow Course Readings

Snow Course Readings

The MRCA partners with several provincial and federal agencies in a watershed-wide water monitoring network. The network collects data on the quantity and quality of our groundwater and surface water resources, streamflows and water levels, weather and snow conditions.

Flood Forecast Monitoring

A network of streamflow and water level gauges throughout the watershed forms a key component of the Authority’s Flood Forecasting and Warning System. Many of these gauges are accessed by satellite and provide important real time information. The data is also used in a variety of water management studies. The Conservation Authority also uses manual staff gauges on many of the smaller streams. Ontario Power Generation, the Ministry of Natural Resources and Water Surveys of Canada are key partners in the operation of the system.

Information on snow depth and water content is collected at six monitoring stations located throughout the watershed. This data is especially useful during the spring melt when streamflows and water levels are at their highest. The information is also very useful for wildlife management purposes and tracking climate change.
