Warming Weather Melting Remaining Snow – Be Cautious near Watercourses (media release, March 8, 2021)

March 8, 2021 – The spring snowmelt is here and the Upper Thames River Conservation Authority (UTRCA) reminds watershed residents to be extremely cautious near watercourses and to stay off of all frozen water bodies.

The UTRCA expects this week’s warmer temperatures to melt most of the snowpack by Wednesday, causing water levels to rise in local streams, rivers, ponds and ditches. The UTRCA expects flows in the main branches of the Thames River and downstream through London to peak on Wednesday during the day and into the early evening.  There is also 15 mm of light rain in the forecast for Thursday, which will extend the period of higher than normal water into the weekend.

While the UTRCA does not anticipate any serious flooding at this time, low lying areas and parklands may be inundated in some areas, such as Harris and Gibbons Parks in London.

“We remind everyone that rivers, streams, ditches, and ponds will be hazardous,” said Teresa Hollingsworth, UTRCA Manager of Community & Corporate Services. “Parents are encouraged to keep children and pets away from all watercourses and off of frozen water bodies.

Banks adjacent to rivers and creeks are very slippery and, when combined with cold, fast-moving water, pose a serious hazard. Any remaining ice cover is weakened and unstable. Flood control reservoirs are especially hazardous due to fluctuating water levels.

The UTRCA’s flood control reservoirs at Fanshawe, Wildwood, and Pittock Conservation Areas are at seasonal levels and are being operated to reduce any downstream flooding. UTRCA officials are monitoring the situation, and will report on any changing conditions as necessary.
