FLOOD MONITORING

Man Checking and Monitoring Water Info

The Long Point Region Conservation Authority monitors precipitation (rain and snow), creek flows, weather forecasts and computer models to determine the potential for flooding on a daily basis. LPRCA staff provides this service to the watershed 24 hours a day, 7 days a week and 365 days a year.

During the winter, snowpack is measured at stations located throughout the watershed to determine the snow water equivalent. Snowpack is the accumulated snow cover on the ground. Snow water equivalent is a measurement of the amount of water contained in the snowpack. It can be considered as the depth of water that would theoretically result if the whole snow pack instantaneously melted.

Snowmelt is a major factor contributing to spring freshet flooding. The quantity of snow is usually expressed in terms of its water equivalent in millimetres (mm). This information is used in flood forecasting and flood risk assessments.

The LPRCA, in partnership with Water Survey of Canada, maintains streamflow recording stations located throughout the watershed. The information from the stream gauge recorders allows staff to monitor the progress of runoff events throughout the watershed to assist with both its flood forecasting and warning and low water response programs.
