May 14, 2019 – As homeowners and municipalities look to clean up after another record flood on the Ottawa River, the need to prevent such damage from happening again and again is clear.

We don’t yet know how much the 2019 flood will cost, but we know it will be much more than prevention. Hundreds of homes were damaged, millions of sandbags were filled, residents were evacuated, public infrastructure was compromised, and military and government staff logged significant overtime. And don’t forget the incalculable loss of photo albums and family keepsakes floating in soggy basements, and the exhaustion of homeowners and volunteers fighting the rising water.

But it could have been worse. Without current regulations, more homes and businesses would have been built in the floodplain, meaning more buildings damaged and more people affected.

The good news is, prevention is possible and infinitely cheaper than recovery – all we have to do is invest in it.

Ottawa’s conservation authorities are a key part of preventing flood damage, as they’re responsible for mapping flood-prone areas, monitoring flood conditions, giving municipalities and residents advance warning, keeping infrastructure like berms, dikes and dams in good working order, and prohibiting new development in flood zones. They also require homeowners in the floodplain to floodproof their homes and septic systems when they rebuild, to prevent future damage.

They do all this on a pretty tight budget (even tighter now due to recent provincial cuts), with the support of their partner municipalities.

Conservation authorities also prevent floods by planting hundreds of thousands of trees each year and protecting critical wetlands to build natural flood resilience right into our communities. Forests and wetlands act like sponges, catching and storing runoff so it percolates slowly into waterways. Without forests and wetlands, rain and snowmelt would have nowhere to go but directly into rivers and lakes, swelling them faster and higher.

Flooding is a natural function, and it will happen more often as extreme weather intensifies. And when today’s flood waters recede and the memories of sandbag walls begin to fade, conservation authorities will need continued public and political support when we are directing development away from floodplains, requiring existing structures to be floodproofed and taking steps to protect forests and wetlands.

We need financial support from all levels of government to continue updating floodplain mapping, operating and maintaining water control structures and monitoring flood conditions. It’s also time for the three levels of government to have serious conversations about buy-out and relocation programs for homeowners in the path of floods.

Cancelling the provincial 50 Million Trees program, reducing conservation authority funding and any weakening of regulations aimed at protecting wetlands or floodplains will only lead to more flooding and millions or billions in damages down the road.

Taxpayers foot the bill when major floods damage communities. Supporting the work of conservation authorities and municipalities to protect people and property from flooding in the first place is much better bang for our buck.

May 14, 2019 — Rideau Valley Conservation Authority (RVCA), in conjunction with the Mississippi Valley Conservation Authority (MVCA) and South Nation Conservation (SNC) is maintaining the FLOOD WARNING issued on April 19, 2019 for the areas under our jurisdiction along the Ottawa River.

The most recent analysis from the Ottawa River Regulation Committee (ORRC) indicate that water levels along the lower Ottawa River from Chats Lake to the Grenville/ Hawkebury area have stabilized and will slowly recede in the coming weeks.

All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk as snowmelt continues along the upper Ottawa River. Levels are expected to remain high for the next two to three weeks. Risk is highly dependent on the amount of precipitation that is received. Residents are strongly urged to keep sandbags in place for now. Updates to all projections will be provided as they become available.

Residents in flood-prone areas are encouraged to closely follow evolving conditions and to take necessary measures. Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.

This FLOOD WARNING is in effect until Friday, May 17, 2019 at 5:00 PM.

RVCA and its Ottawa partners, MVCA and SNC monitor the water levels and weather forecasts with the Ministry of Natural Resources and Forestry as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.

The Ottawa River Regulation Planning Board will be reassessing forecast conditions and providing hydrological condition updates on its website daily at www.ottawariver.ca/forecast.php.

May 13, 2019 —A FLOOD WATCH is being maintained for properties around Bobs Lake and Christie Lake.

The water levels on both lakes continue to decline slowly and remain above average for this time of year.  The current water level on Bobs Lake is above the ‘Full Supply’ threshold at which flood damage can occur.  The current water level on Christie Lake is such that some flood damage can also occur. The current forecast indicates up to 30 mm of rain could fall between today and Wednesday. This rainfall will likely increase water levels again on Bobs Lake and Christie Lake. Parks Canada staff are closely monitoring the water levels in these lakes.  Operations at the Bolingbroke Dam will take place as required to balance the levels in Bobs Lake and Christie Lake.

Water levels are now near seasonal in the rest of the Rideau Valley Watershed.

Everyone needs to be cautious around lakes and streams with the fluctuating water levels. Children need to be educated about the hazards and kept away from all watercourses.

This watershed conditions statement is in effect until Tuesday May 21, 2019 at 5 PM and will be updated at that time unless the forecast or conditions change.

May 13, 2019 — Do you love being outside, getting your hands dirty and doing some good for the planet? Are you interested in science or biology, but want to skip the degree? We’ve got just the job for you.

The RVCA’s City Stream Watch program needs volunteer ‘citizen scientists’ to help monitor, protect and clean up the city of Ottawa’s many urban and rural streams. From invasive species removal to assisting with aquatic wildlife surveys, citizen scientists are the backbone of the program that monitors the health of urban and rural tributaries flowing into the Rideau and Ottawa rivers.

This is the best time to get involved, since a volunteer training session will be held May 25 to welcome new recruits and introduce them to the basics of stream sampling and environmental data collection. 

Long-time volunteer Larry Hum encouraged residents to “give it a whirl” – especially if they’ve got an interest in biology or the environment.

“It’s an opportunity to work in bioscience without going into the heavy, heavy science,” he said.

Acting program co-ordinator Rosario Castanon-Escobar said it’s volunteers like Mr. Hum that make this program such a resounding success, year after year.

“The result of our work together is that our streams continue to be valued, respected and cared for to ensure these streams remain a point of pride within our communities,” said Castanon-Escobar.

This year’s volunteer training session is scheduled for Saturday, May 25 from 10 a.m. to noon along the shores of Sawmill Creek near Billings Bridge. All necessary equipment is provided and there is no cost to volunteers. Interested participants must pre-register for the event by contacting Castanon-Escobar at .

The 2019 program will collect data on Cranberry Creek in Kars, Hunt Club Creek in Hunt Club, Ramsey Creek in Gloucester/Mer Bleue and Borthwick Creek in Gloucester/Mer Bleue. Sampling activities will focus on assessing the habitat, water and shoreline conditions of the streams. The team will also organize several cleanups, shoreline planting events and invasive species removals throughout the season.

In the 17 years since its inception, City Stream Watch has enlisted the help of more than 3,100 volunteers, contributing more than 15,000 hours toward conservation projects and monitoring. All are welcome to participate. Results from our 2018 efforts are available online at www.rvca.ca.

The program is a community-based partnership, which includes the City of Ottawa, the Canadian Forces Fish & Game Club, the Ottawa Flyfishers Society, the Rideau Roundtable, the Ottawa Stewardship Council, National Capital Commission and Rideau Valley Conservation Authority.

For more information about the program, including the reports of streams previously studied, please visit www.rvca.ca/volunteer/city-stream-watch.
