Flood Watch – Lake Ontario Shoreline

Flood Watch – Lake Ontario Shoreline

The Hamilton Conservation Authority (HCA) is advising of strong shore-bound winds expected on Saturday and Sunday (October 27 and 28).  There is an increased risk of shoreline erosion and localized flooding along Hamilton’s shoreline, due to storm surge and wave action. 

Forecasts anticipate strong sustained winds from the north-east and east of up to 35 km/hr, with maximum wind gusts of up to 65 km/hr.  Resulting wave heights of up to 2.2 m are expected.

HCA wishes to remind residents to exercise caution near lakefront areas during this time, as high winds, high water levels and wave action may pose significant erosion, flooding and public safety hazards. 

A close watch on shoreline and weather conditions is recommended.  HCA staff continue to monitor Lake Ontario wind conditions and lake levels closely.

Currently, the Lake Ontario water level is approximately 74.6 m IGLD85, which is average for this time of year.  For reference, the HCA shoreline flooding hazard level used for planning and development review is 78.5 m (which includes a lake level of 76.00 m and 2.5 m of wave action).

This Flood Watch message is in effect until Monday, October 29, 2018, at which time it will either be updated or cancelled.   HCA will issue updates prior to October 29 as warranted.
