flood here often?


 Here's a treat for homeowners living on or near the Rideau River floodplain, or indeed for anyone who enjoys a good natural calamity.

The map comes from the Rideau Valley Conservation Authority and shows projected flooding in the Brantwood Park and Hurdman Woods areas for a once-in-a-hundred-year high-water event. The image combines historical flood-level records with modern topologic and built landscape data. The map, and many more like it, can be accessed on the RVCA website at https://www.rvca.ca/watershed-conditions/neighbourhood-flood-maps.

As described by the RVCA...

"Within the RVCA’s regulated floodplain, staff have identified a number of Flood Vulnerable Areas throughout the watershed where flood events may have an impact on nearby properties... A series of new Neighbourhood Flood Maps for 20 vulnerable City of Ottawa communities along the Ottawa and Rideau Rivers shows the potential extent of flooding for 1:2, 1:5, 1:10, 1:20, 1:50 and 1:100 year return period floods for these neighbourhoods."

Ottawa residents will be especially interested in the maps for areas downstream from Hog's Back Falls — Brewer Park (who remembers Nordic Circle?), Windsor Avenue, Rideau Gardens, Brantwood Park, Kingsview Park, and New Edinburgh.

Yes, New Edinburgh.

This would be Creighton Street, perhaps during the great flood of March, 1898 (there were quite a few.) I can't find the photographer's name, but Messers Jarvis and Pittaway took pictures of the event and displayed them at their studios. I'm sure Topley would have swung by as well.
