Shoreline Flood Watch [ Flood Message #1 ]
March 24, 2023Long Point Region Conservation Authority is issuing a Flood Watch for the Haldimand County shoreline and a Shoreline Conditions Statement: Flood Outlook for the remaining areas along the shoreline within the LPRCA watershed.
A significant weather system is forecast to bring high winds to the Lower Great Lakes Region tomorrow Saturday, March 25, 2023. Areas along Lake Erie will see winds from the east and southeast at 44 km/hour up until early afternoon on Saturday before changing directions to the southwest early evening. Winds from the southwest are expected to reach 62 km/hr with gusts up to 92 km/hr before slowly diminishing into Sunday morning. Forecast winds across Lake Erie will result in increased water levels due to storm surge and wave heights, with the potential to reach local flood thresholds in Haldimand County. This may result in minor shoreline flooding, wave uprush and increased erosion across the area.
For the eastern end of Lake Erie, a moderate storm surge is forecasted, with water levels at Port Colborne expected to peak around 2.1 m above chart datum over the next 24 hours. Water levels in Long Point are expected to peak around 1.67m above chart datum over the next 24 hours. The Lake Erie shoreline wave height is predicted to be slightly over 1.5 m for the eastern watershed while the central watershed will have waves ranging from 2.5 to 3.5 m during this event.
Residents are urged to use caution and stay away from Lake Erie shoreline areas experiencing strong wave action and elevated water levels. Parents are reminded to keep children and pets away from these areas. A close watch on local weather conditions is recommended.
The Haldimand County Flood Coordinator should be prepared to warn affected residents and businesses in Lake Erie Flood Zone 1, along the lakeshore and to monitor roads along the lakeshore and implement closures as necessary. The public is advised to familiarize themselves with flood warning zone mapping available on Haldimand County’s website.
Community flood coordinators in other jurisdictions are asked to monitor road conditions along the lakeshore. LPRCA staff will continue to monitor Lake Erie conditions and will update this message as necessary.
This Flood Watch is in effect until 8:00 am Sunday, March 26, 2023. LPRCA staff will continue to monitor conditions throughout the watershed and will update this message as necessary.

Watershed Conditions Statement – Riverine Flood Outlook [ Flood Message #1 ]
March 22, 2023The Long Point Region Conservation Authority is issuing a Watershed Conditions Statement – Riverine Flood Outlook for all areas within its watershed.
A strong low-pressure system is expected to move into the province this evening. Precipitation across southern Ontario is forecast to reach 15 – 20 mm today with an additional 15 – 25 mm on Saturday. Additionally, above-freezing daytime air temperatures, as high as +10°C, are forecast for southern Ontario over the next four days. A moderate snowpack, ranging from 0 – 6.9 cm has been recorded throughout the watershed.
The above-freezing temperatures with added rain will result in the snowpack becoming saturated with water. It is expected that the entire snowpack will melt and release water which will create a potential for flooding in flood prone areas through the week into the weekend.
Members of the public are reminded to stay away from ditches, streams, rivers and ponds as the combination of slippery banks and cold, fast-flowing water is dangerous. Parents are reminded to keep children and pets away from these areas.
Landowners are also advised to make sure dams, culverts, and catch basins are free from debris and functioning properly – if it is safe to do so.
Water levels are expected to remain high for several days. Therefore, this Flood Outlook is in effect until Tuesday, March 28, 2023. LPRCA staff will continue to monitor conditions throughout the watershed and will update this message as necessary.

Shoreline Conditions Statement – Water Safety Message [ Lake Flood Message #1 ]
March 17, 2023Long Point Region Conservation Authority is issuing a Water Safety Statement for the Lake Erie Shoreline.
A strong low-pressure system has begun to move into the LPRCA watershed. This system is expected to bring strong
southwesterly winds which are expected to affect Lake Erie starting this afternoon. Wind speed is forecasted to reach
45 km/hr with potential gusts up to 70 km/hr, peaking this evening. As the system moves eastward on Saturday the
winds will begin to dissipate.
Shorelines across Lake Erie will result in increased water levels due to storm surge and wave heights. Due to the
forecast of strong southwesterly winds, the Long Point Region Conservation Authority is issuing a Shoreline
Conditions Statement –Water Safety Statement. This may result in minor shoreline flooding, wave uprush, and
increased erosion along the Lake Erie shoreline. LPRCA does not anticipate that the combined water level and wave
height will exceed local flood thresholds.
The public is asked to stay away from the Lake Erie shoreline due to strong wave action and elevated water levels.
Parents are reminded to keep children and pets away from these areas.
Water levels are expected to remain high until Saturday morning therefore, this Shoreline Conditions Statement –
Water Safety Statement is in effect until 8:00 am, Saturday, March 18th, 2023.
LPRCA staff will continue to monitor forecasted conditions and will update this message as necessary.
Contact David Proracki, Water Resource Analyst at lprca.floodmessage@lprca.on.ca or 519-842-4242 ext. 264 should
further information be required.
Watershed Conditions Statement – Water Safety Message [ Flood Message #1 ]
March 16, 2023Long Point Region Conservation Authority is issuing a Water Safety Statement for all areas within its watershed.
On March 16th at approximately 8:00 pm, a strong low-pressure system is forecasted to enter the LPRCA watershed
and slowly cross the watershed for the next two days. The system carries warm air and a significant amount of
precipitation. Air temperatures in the LPRCA watershed are expected to stay above freezing temperatures overnight
and reach 7 – 10 degree Celsius on Friday. Total precipitation accumulation amounts for the duration of the two-day
event are forecasted to reach 15-25mm.
A snowpack, of approximately 7 – 20 cm and frozen ground conditions are expected to affect the LPRCA watershed
during this event. Under the forecast of mild temperatures, the snowpack will start to melt. Melting snow, rain, and
frozen ground conditions will produce substantial runoff. Due to the forecast of rain and warm temperatures and
considerable snowpack, the Long Point Region Conservation Authority is issuing a Watershed Conditions
Statement –Water Safety Statement. Under the forecasted conditions, riverine water levels and flows will increase.
No major flooding is expected to occur based on this forecast however; some watercourses may reach or exceed their
banks creating localized flooding in floodplains, low-lying areas and regions with poor drainage.
People are warned to stay away from ditches, frozen water bodies, streams, rivers and ponds as the combination of
slippery banks and cold, fast-flowing water is dangerous.
Landowners are also advised to make sure dams, culverts, and catch basins are free from debris and functioning
properly; if the work can be done safely.
Water levels are expected to remain high for the weekend. LPRCA staff will continue to monitor watershed conditions
and will update this message as necessary.
Therefore, this Watershed Conditions Statement – Water Safety Statement is in effect until noon, Monday,
March 20th, 2023.
LPRCA staff will continue to monitor forecasted conditions and will update this message as necessary.
Contact David Proracki, Water Resource Analyst at lprca.floodmessage@lprca.on.ca or 519-842-4242 ext. 264 should
