SNC flood outlook acknowledges possibility of localized flooding

FINCH — There’s no prospect of severe flooding, but South Nation Conservation (SNC) cautions that heavy forecasted rain is expected to raise levels in local watercourses and increase runoff within the watershed this week.

Residents in low-lying areas may observe minor to nuisance flooding, according to the local watershed authority, which issued a statement on the situation today (July 24). It says there’s “very high” potential for blocked storm drains, catch basins, and culverts, which may lead to localized flooding.

SNC notes that Environment Canada forecasts 40 to 60 mm of precipitation over the next 24 hours, with potential for over 100 mm of precipitation in the St. Lawrence Valley area.

Water levels this year are already slightly above normal, according to SNC, which advises residents to avoid watercourses where flows are high and banks may be unstable. Parents are encouraged to explain these dangers to their children.

SNC says its 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 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, posted on our Facebook page (/SouthNationConservation), or Tweeted to us (@SouthNationCA).

Today’s flood outlook statement by SNC remains in effect until Monday, July 31.
