A melt is coming, but don’t panic about flooding, says conservation authority

Mild temperatures and a rainy forecast have many people in the Ottawa region on edge with fears that the melt will lead to flooding.

The Rideau Conservation Authority says the snow pack has more water in it this year than in any previous year in their 30-year record. However, Terry Davidson, director of engineering and regulations with the conservation authority, says it’s not as bad as it seems.

“We don’t actually expect over the next couple days to see much movement in the main water courses, some of the smaller drains and creeks may open up but we don’t expect to see the Rideau River open up just because the snow pack has the ability to absorb all that rain,” he explained.

Sarah MacLeod-Neilson is one of the conservation authority’s scientists taking core samples of the snow pack in order to predict the melt.

“We want a measure of the snow depth and then the total weight of our cores to have an idea of the water equivalency of our snow pack,” MacLeod-Neilson said.

Orléans Coun. Mathew Luloff said he spent Thursday addressing flooding concerns across his ward.

“Residents are incredibly worried about what’s going to happen on their streets. That’s why we have our roads crew really really concentrating on the catch basins right now to make sure those catch basins are clear. If residents have the opportunity and the strength to get out there and help us to chip away at those storm drains that’s going to make all the difference,”  says Luloff who is working in the ward full time with rain expected overnight Thursday.

Luloff says the areas of highest concern for him are Convent Glen, Orléans Wood, Queenswood Heights and, especially, Fallingbrook.

The worries about clearing storm drains are keeping Bryden Denyes, area manager of core roads for the City of Ottawa, busy as well. 

He says crews are working as hard as they can to hit known trouble spots and fill potholes.

“Spring is definitely starting to come out now. We’re doing active drainage operations for localized flooding on roadways and sidewalks. We’re also ensuring we have a complete inventory of sandbags and sand for residents so we’re monitoring conditions. We work very closely with Rideau Valley Conservation Authority, Ottawa river keepers and Mississippi Valley Conservation Authority to get flood predictions,” Denyes said.
