Watershed Conditions 

For Immediate Release
Contact: GRCA Duty Officer 
Phone: 519-621-2761 

Warmer weather with rain is moving into the watershed today. Rain started this morning and is forecast to continue until early Friday, with the heaviest rain from 5 p.m. to 7 p.m. today. Across the watershed, about 35 mm of rain is forecast, with totals reaching 50 mm in areas where thunderstorms occur.

Temperatures will rise through the day today and overnight when the temperature will reach 14C. Temperatures will fall rapidly Friday as the rain moves out of the area. Overnight temperatures Friday evening into Saturday morning are forecast to fall to 1C.

River and stream flows will rise with the size of the increase depending on the amount of rain. Major flooding is not anticipated, however flooding of low-lying areas that traditionally flood can be expected. It also expected the low-level bridge on Three Bridges Road near St. Jacobs on the Conestogo River may have to be closed.

The major reservoirs at Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shades have storage available to manage runoff and will be operated to reduce downstream flooding.

Residents are reminded to use extreme caution near all watercourses and water bodies. Stream banks are slippery, and the water is very cold. Parents are reminded to keep children and pets away from watercourses.

GRCA staff will be keeping a close eye on the situation and will issue updates as required.. This message is in effect until Monday April 13th.
