One of the primary functions of the Niagara Peninsula Conservation Authority is to administer and operate a Flood Warning System to reduce the risk to life and property due to riverine and shoreline flooding.

Numerous areas within the watershed of the Authority are naturally flood-prone and will be inundated on a periodic basis. Other locations of the watershed may experience flooding at infrequent times, due to various causes, including heavy spring runoff/snow melt events, extreme precipitation events, ice jams and high lake level events generate by strong winds.

These are three types of flood messages that the NPCA typically issue. They are:

Bulletin - A Flood Safety Bulletin is defined as a general notice that potential conditions exist that pose a risk to personal safety and will be issued to schools and media sources. Flood Safety Bulletins may be posted when streams are flowing at near bankfull levels, when ice conditions are unsafe, or when stream banks are icy, soft, and/or slippery.

Advisory - A Flood Advisory is defined as a notice of the potential for flooding to occur in the near future. The Flood Advisory is based upon information received by the Conservation Authority's weather monitoring systems, and is intended to provide notice to municipalities and emergency services that measures should be taken to prepare for a possible emergency. Flood Advisories may be updated depending upon weather and runoff conditions, and will be followed by a notice of cancellation once the potential for flooding has passed.

Warning - A Flood Warning is defined as a notice that flooding is imminent or occurring. The Flood Warning is based upon information received by the Conservation Authority's weather monitoring systems, and is intended to provide notice to municipalities and emergency services that action is required on their part. Flood Warnings may be updated depending upon weather and runoff conditions, and will be followed by a notice of cancellation once the potential for flooding has passed.

Weather conditions are monitored daily, as are riverine and shoreline conditions in the watershed. In the event that watershed conditions deteriorate, or if a severe weather forecast is predicted, the Authority will issue advisories and warnings to affected jurisdictions so they may prepare for a possible flood event.
