Forecast Rain will keep Streams and Rivers High (flood bulletin, February 28 – March 3, 2017)

Watershed Conditions Statement – Water Safety (Issued February 28, 2017 at 12:30 pm; Valid until March 3, 2017)

Current forecasts call for between 30 and 40 mm of rain, starting Tuesday, and continuing into Wednesday. There is a risk of thunderstorms tonight.

Recent rain has kept streams and rivers in the Upper Thames River watershed elevated. At this point there is little to no snow left in the watershed.

With saturated, spring-like ground conditions, forecast rainfall will produce runoff into watercourses. Expect streams to remain elevated throughout the week, with the most likely timing of flow peaks beginning on Wednesday, and into the early hours of Thursday morning, as the crest moves downstream into London.

With the current forecasts, stream flow rates are generally expected to be similar to the flows observed in recent runoff events, with some minor flooding of low lying areas. Localized higher flows could be observed as a result of thunderstorm activity. The UTRCA’s flood control reservoirs at Fanshawe, Wildwood and Pittock Conservation Areas will be operated to assist in managing runoff.

Municipal staff should monitor local drainage problem areas.

Residents are reminded to use extreme caution near all watercourses, and keep children and pets away. Streambanks are slippery, the water is very cold, and any remaining ice is unstable and thin.

UTRCA officials are monitoring the situation, and will report on any changing conditions if necessary.
