Conservation Halton issued the following Watershed Conditions Statement – Flood Outlook at 12:10 p.m. on Monday, April 7, 2014.
The forecast for this afternoon and evening includes high intensity rainfall and above zero temperatures. The forecasted rainfall is approximately 20mm coming into our area later this evening and into tomorrow morning. This is a trailing system and may be long lasting and continuous in certain areas across the Conservation Halton watershed.
The rainfall and mild temperatures last week increased the flows and water levels in the rivers and creeks but did not exhibit any major flooding concerns. The creeks have receded since Friday and are running at near normal levels.
There are still snow covered forested areas in the upper reaches of the watershed which will also contribute to the runoff from this forecasted system. Blockages at bridges and culverts may produce localized flooding concerns due to remnant debris at bridges and culverts from the ice storm in December. Localized flooding in low-lying and flood prone areas may be expected.
Conservation Halton’s 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 the end of Tuesday, April 8, 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.
