Spring Freshet Update (flood bulletin, March 10-15, 2021)

FLOOD WATCH
Issued March 10, 2021 at 3 pm; Valid until March 15, 2021

Snowmelt has been slower in the north part of the Upper Thames River watershed than in the south. As a result the Upper Thames River Conservation Authority (UTRCA) now expects peak flows in the main branches of the Thames River and downstream through London to occur Thursday night and into Friday. The South Thames in London may peak earlier than the North Thames River. The forecast for Thursday now calls for 10 mm of light rain, which will have a minor impact on peak flows.

Serious flooding is not expected at this time, but some low lying areas and parklands will likely be inundated, such as the St. Marys Flats, and Harris and Gibbons Parks in London. Watercourses are expected to remain elevated into early next week.

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.

The public is reminded to exercise extreme caution and stay away from all water bodies. Any ice cover is weakened and unstable. Flood control reservoirs are especially hazardous due to fluctuating water levels. Banks adjacent to rivers and creeks are very slippery and, when combined with cold, fast-moving water, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off of frozen water bodies.
