FLOOD WATCH: ST. LAWRENCE RIVER – UPDATE #4

May 23, 2017

This statement is an update to South Nation Conservation’s (SNC) Flood Watch: St. Lawrence River issued on May 16, 2017. 

Environment and Climate Change Canada is forecasting 10 to 15 mm of precipitation for this week, which is not expected to have any significant effect on water levels.

According to the International Lake Ontario – St. Lawrence River Board, “Lake Ontario’s water level remains the highest since 1918 and the outflow is now at its highest since 1998.” The Moses-Saunders Dam in Cornwall and Long Sault Dam are being operated to account for the outflow from Lake Ontario.  Lake St. Lawrence water levels are expected to peak today, and will begin to slowly drop tomorrow. 

SNC continues to caution residents along low-lying areas of the St. Lawrence River in the Township of Augusta, Township of Edwardsburgh/Cardinal, and the Township of South Dundas. 

Residents are also advised that wind may cause higher waves, further aggravating water levels which may affect structures closer to the shore.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable.  Parents are encouraged to explain these dangers to their children.

Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change.

The public is encouraged to visit www.nation.on.ca and to also report changes in water-related conditions, soil stress fractures (i.e. cracks in soil), abrupt changes in streambanks, or sudden leaning of trees in their local areas. All feedback and photos can be sent to waterwatch@nation.on.ca, posted on our Facebook page (/SouthNationConservation), or Tweeted to us (@SouthNationCA).

FLOOD OUTLOOK STATEMENT: OTTAWA RIVER - UPDATE

May 23, 2017; Time: 11:00 a.m.

This statement is an update to South Nation Conservation’s (SNC) Flood Outlook Statement: Ottawa River issued on May 16, 2017. 

Ottawa River Regulation Planning Board has stated “Current weather forecasts predict significant rainfall over the coming week, particularly in northern sectors of the basin. With northern reservoirs now full, the risk of large flow releases from northern reservoirs exists and will be determined by the amount of rainfall received. Upstream locations from Mattawa down to the Lac Coulonge area may see a rapid increase in levels. Depending on precipitation amounts received, downstream locations from Chats Lake down to the Grenville/Hawkesbury area may see levels stop decreasing next week. Residents in low lying areas are encouraged to continue to closely watch for updates in forecasts”.

Environment and Climate Change Canada forecasts 15 to 25 mm of rain this week.  Therefore, water levels between Gatineau and Hawkesbury are expected to recede slowly.  Severe flooding is not a concern at this time; however, nuisance flooding in low-lying areas may be observed.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable.  Parents are encouraged to explain these dangers to their children.

Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change.

The public is encouraged to visit www.nation.on.ca and to also report changes in water-related conditions, soil stress fractures (i.e. cracks in soil), abrupt changes in streambanks, or sudden leaning of trees in their local areas.

OTTAWA RIVER FLOOD WARNING DOWNGRADED

May 16, 2017; Time: 4:00 p.m.

South Nation Conservation’s (SNC) is downgrading the “Flood Warning: Ottawa River” statement issued on May 12, 2017 to “Flood Outlook: Ottawa River”. 

Ottawa River Regulation Planning Board stated “Most heavily flooded areas, between Lac Coulonge and the Hawkesbury/Grenville area, are now free of high waters. Water level decline is expected to continue throughout the coming week. Snowmelt from the north has been retained by northern reservoirs. As long as waters remain on the flood plain there continues to be a risk of returning to flooding levels in response to possible widespread heavy rainfall events. Residents in low lying areas are encouraged to continue to closely watch for updates in forecasts”.

Environment and Climate Change Canada forecasts only 5 to 10 mm rain this week.  Therefore, water levels between Gatineau and Hawkesbury are expected to recede slowly.  Severe flooding is not a concern at this time; however, nuisance flooding in low-lying areas may be observed.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable.  Parents are encouraged to explain these dangers to their children.

Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change.

FLOOD WATCH: ST. LAWRENCE RIVER – UPDATE #3

May 16, 2017

This statement is an update to South Nation Conservation’s (SNC) Flood Watch: St. Lawrence River issued on May 12, 2017.

According to the International Lake Ontario – St. Lawrence River Board: “Water levels on the St. Lawrence River may fluctuate; rising and falling as seen in recent weeks. Ontario Power Generation and the International Lake Ontario – St. Lawrence River Board are operating water control structures to keep the water levels steady”.

Environment and Climate Change Canada forecasts no significant precipitation for this week. However, Lake Ontario’s water level is the highest it has been since 1918; the International Lake Ontario – St. Lawrence River Board increased the outflow again yesterday afternoon. Water levels may fluctuate along the low-lying areas of the St. Lawrence River.

South Nation Conservation (SNC) continues to caution residents along low-lying areas of the St. Lawrence River in the Township of Augusta, Township of Edwardsburgh/Cardinal, and the Township of South Dundas.

Residents are also advised that wind may cause higher waves, further aggravating water levels which may affect structures closer to the shore.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain these dangers to their children.

WATERSHED CONDITIONS STATEMENT – FLOOD OUTLOOK

May 1, 2017                                                                                       

South Nation Conservation (SNC) cautions residents that water levels are expected to rise this week due to heavy rainfall.

Environment and Climate Change Canada is forecasting approximately 30-60 mm rain for this week. The forecasted weather will cause fast runoff to watercourses, which will increase river levels and flows throughout the South Nation watershed.  

Severe flooding is not a concern at this time; however, nuisance flooding in low-lying areas may be observed. Furthermore, potential for blocked storm drains, catch basins and culverts are very high which may also cause localized flooding. 

Residents are advised to stay away from rivers as the forecasted weather may rapidly increase river flows and banks might be unstable and slippery. Parents are encouraged to explain these dangers to their children.

Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change. 

The public is encouraged to visit www.nation.on.ca and to also provide feedback with respect to changes in water related conditions in their local areas. All feedback can be sent to waterwatch@nation.on.ca, posted on our Facebook (/SouthNationConservation), or Tweet us your photos (@SouthNationCA). 

For more information, please contact Golam Sharif at 1-877-984-2948 ext. 373 or Jason Symington at 1-877-984-2948 ext. 230.

This statement is in effect until Monday, May 8, 2017.
