Flood Watch – Watercourse Flooding
Posted on 07/15/2024
Watercourse

Effective until Wednesday, July 17, 2024 – The Hamilton Conservation Authority (HCA) is advising that water levels and flows in all area watercourses are expected to increase significantly, as a result of the rain and potential thunderstorms forecasted for today and tomorrow (July 15 and 16). Localized watercourse flooding of low-lying areas that typically flood during higher water levels is expected.

In addition, there is potential for significant watercourse flooding, as large amounts of runoff are expected to occur.
Over the remainder of today (July 15), the Hamilton area may receive between 1 and 42 mm of rain (this includes 1 to 32 mm of forecasted rain, with an additional 5 to 10 mm possible if thunderstorms occur). Tomorrow (July 16), the Hamilton area may receive between 3 and 29 mm of rain (this includes 3 to 19 mm of forecasted rain, with an additional 5 to 25 mm possible if thunderstorms occur).

HCA is asking all residents and children to keep a safe distance from all watercourses and structures such as bridges, culverts, and dams. Elevated water levels, fast flowing water, and slippery conditions along stream banks continue to make these locations extremely dangerous. Please alert children in your care of these imminent dangers.

Current water levels and flows in area watercourses are at elevated well above baseflows and near thresholds for significant water safety concerns. However, there are currently no significant watercourse flooding concerns.

This Flood Watch message is in effect until Wednesday, July 17, 2024, at which time it will either be updated or cancelled. HCA will issue updates prior to July 17 as needed.
