Water Conditions Statement - Water Safety

Apr 25, 2018 -

The snow melt trend that started early this week will continue due to above-zero daytimes temperatures, prompting the North Bay-Mattawa Conservation Authority (NBMCA) to issue a water safety statement.

"A low pressure system is moving through the province Wednesday (today) and Thursday, bringing rainfall and continuous warmer weather to the North Bay-Mattawa region.  This system is forecast to bring rainfall of 20-35mm total.  The North Bay-Mattawa region has already received around 15mm since last night.  Temperatures today will climb into the high single digits, continuing to melt the existing snow pack," said Katelyn Lynch, NBMCA's duty officer.

The rainfall forecasted over the next 24 hours will cause increased runoff to watercourses and water bodies.  Warm weather is forecast for the next 5 days which will continue to cause snow melt and runoff.  This runoff will lead to higher than normal water levels throughout the North Bay-Mattawa region.  Flooding is not anticipated at this time.

NBMCA conducted a snow survey on Monday, April 23.  Snow depths range between 22 and 39 cm in the NBMCA watersheds.  Average water equivalence of the snow pack ranges between 79mm in the La Vase River subwatershed, 99mm in the Kaibuskong River subwatershed, and 123mm in the Chippewa Creek subwatershed.  Much of the snow pack has started to melt with the warmer temperatures and rain received this week.

Banks adjacent to rivers and creeks are very slippery at this time and when combined with cold open water, pose a serious hazard. Parents are encouraged to keep their children and pets away from watercourses and off water bodies that have thinning, unsafe ice.

Staff at the North Bay-Mattawa Conservation Authority will continue to monitor weather and watershed conditions and provide updates if conditions change.

The general public is advised of these messages through the www.nbmca.on.ca website with the flood status icon and a link to information about current conditions. NBMCA also issues these messages to local media.

This message will be ineffect until (or updated before) Monday April 30, 4:00pm.
