Following up on a talk by Michael Sarich of the Ottawa River Regulation Secretariat at our AGM, here are his slides about why flooding happens, what can be done, and the history of flooding on the Ottawa river.
He’s also provided a frequently asked questions document from the Ottawa River Regulation Planning Board (see https://ottawariver.ca/ for general information and bulletins).
As mentioned in a post on Facebook by our city councillor Jeff Leiper, sewer overload warnings have been delivered to the appropriate houses (a flyer or fire department visit); if you didn’t get one then there’s no worry about keeping usage down.
The Pontiac and Keyworth sandbag wall should be okay; the water won’t be rising too much and should mostly affect low driveways there.
Also the Patricia sewer overflow seems to be mostly ground water coming from upstream (higher water pressure). I assume it’s better to let it flow out there than filling the pipes.

Jeff Leiper’s office has suggested that reducing household discharge to the sanitary sewer system for the next few days could help reduce the risk of over-taxing the water system. Which means reducing usage by following cottage rules and cutting down on deep baths/long showers/etc:
If its yellow, let it mellow. If its brown, flush it down.
This is because river water is getting into the system. One of our residents writes:
Our concern was heightened this morning when a manhole cover at the corner of Pontiac and Patricia blew off from increased water pressure caused by the city blocking the sewer pipe yesterday on Pontiac behind the school. It’s still spouting a column of water and flooding the forest on the west side of Patricia and creeping towards Clearview. All they accomplished was pushing the problem 200m west.

By the way, Dovercourt is making their showers available if you need them.
Our neighbours to the west in Westboro could use some help with reinforcing the sandbagging at the north part of Churchill Avenue. If you have an hour to spare (or a wheelbarrow or other sandbag mover), head over to there (about a 20 minute walk). Details in their Facebook post.
Thanks everyone for helping out, the sandbagging is complete in our neighbourhood, for now. If you want to join the roving bands of sandbaggers (a bunch of them showed up in an OC Transpo shuttle bus), check out the city web site or ask around (councillor Jeff Leiper’s staff would know).

Sandbagging Complete – Site all cleaned up too!
The City has dropped off sand bags and now we need a few more volunteers to help place them. Pontiac Street between Keyworth and Cowley. Also, a few wheelbarrows would be welcome!
Here are a few photos of flooding around the neighbourhood this morning. Pontiac Street has flooded near the St. Georges school. And of course the Remic Beach (apparently that’s what it is officially called) at the end of Carleton Avenue is mostly under water.
