WATERSHED CONDITIONS STATEMENT – Flood Outlook
Date: March 1, 2017
This notice is intended to advise the public and local municipalities of the status of the watercourse conditions within the Niagara Peninsula and the eastern portions of the City of Hamilton and Haldimand County.
The Niagara Peninsula and portions of Hamilton and Haldimand have received between 5 to 30mm of rain throughout the overnight hours. The headwaters of the Welland River and Twenty Mile Creek, in Hamilton and West Lincoln, received the highest amount of precipitation. The precipitation combined with saturated ground has resulted in higher than normal water levels and flows within these systems. At present, the upper reaches of the Welland River, Twenty Mile Creek, and the tributaries of these systems are elevated but appear to be cresting and should remain below critical thresholds. The Niagara Peninsula Conservation Authority does not expect any major flooding at this time. However, localized flooding typical of low lying areas may be experienced. The NPCA will continue to monitor stream and weather conditions closely and will issue further messages as required.
Portions of southeastern Niagara are presently under a wind warning issued by Environment Canada. Very strong west to southwest winds of 70 km/h gusting to 90 km/h are expected tonight and are anticipated to diminish on Thursday. Residents along the Lake Erie shoreline may experience elevated lake levels, severe wave action, and possible back shore flooding.
Residents are urged to keep themselves, children and pets well away from streams, creeks and Lake Erie as these waterbodies will be hazardous. Drivers are reminded there is an increased risk of water over roads and should not drive through any flooded roadway, being particularly careful at night. Local municipalities are advised to check for debris clogging culverts, catch basins, and other storm infrastructure.
Information on the Flood Status in the watershed and water levels within the streams can be found on the NPCA’s website at https://npca.ca/flood-status.
This notice is in effect until noon Thursday, March 2nd, 2017 and will be updated as required.
What if a Flood Message is Issued for Your Area?
- Take heed of the message issued.
- Be prepared to follow the advice and instructions of emergency response officials.
Monitoring weather and flood conditions is a shared responsibility of Conservation Authorities, OMNR, and Environment Canada. The OMNR Surface Water Monitoring Centre in Peterborough monitors weather forecasts and water levels across the province, providing the information to Conservation Authorities. Other information is also available from Environment Canada. Conservation Authorities and the Ontario Ministry of Natural Resources are responsible for forecasting where and when flooding is likely to occur and issuing appropriate messages. Advance warning of an impending flood allows municipalities and other government agencies to put emergency response plans into operation, and if necessary, evacuate communities. When flooding is possible or about to occur, Conservation Authorities (or the Ministry of Natural Resources in areas where there is no Conservation Authority) issue flood messages to municipal emergency management officials and the media. The municipal officials then take action to warn local residents. Flood messages are posted on Conservation Authorities’ websites. In some watersheds, members of the public can receive flood messages directly through e-mail and/or Twitter.
