Conservation Halton issued the following Watershed Conditions Statement – Flood Outlook at 2:45 p.m. on Thursday, April 3, 2014.
The forecast for the coming 24 hours includes above zero temperatures along with the proposed rainfall of 10 to 15mm for our region. In addition, the beginning of next week brings the potential for additional rain and continued spring like temperatures around 7 degrees or greater.
The warmer weather experienced earlier this week has steadily increased snowmelt and contributed to runoff throughout our watershed. This removed a lot, if not all of the ice cover from the creeks in Halton. The forested areas in our upper watersheds (north of Highway 401) still have substantial snow cover and will continue to feed our creeks with additional runoff with the proposed mild temperatures and rainfall.
It is expected we will experience an increase in flows and water levels in our creeks throughout Halton. Blockages at bridges and culverts may produce localized flooding concerns due to remnant debris at bridges and culverts from the ice storm in December however; widespread flooding is not currently anticipated.
Our reservoirs are taking on additional water and rising as part of the nature of our seasonal operations.
Conservation Halton is asking all residents and children to stay away 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.
Conservation Halton will continue to monitor stream and weather conditions and will issue further messages as necessary. This Watershed Condition Statement will be in effect through to Monday, April 7, 2014.
Note: A Watershed Safety Statement – Flood Outlook is an early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.
