May 7, 2019 – As thousands of Canadian students walked out of class to protest climate policies on May 3, a group of Nepean High School students were taking their protest back to basics.

Shovels in hand, the 14-person crew braved wet weather to plant 500 trees at MacSkimming Outdoor Education Centre in Cumberland. Rideau Valley Conservation Authority (RVCA) provided the seedlings and taught the students how and where to plant them.

“I like that we’re taking real action, we’re out here actually planting trees,” said Emily Drummond, a Grade 9 environment club member. The club had planned to join the #FridaysForFuture climate strike at Parliament Hill, but decided they could have a more immediate impact reforesting an abandoned field.

Most of the students were in Grade 11 or 12 and part of the school’s environmental Specialist High Skills Major (SHSM) program. They take courses in habitat ecology, resource management and environmental science as part of their core curriculum. Most said they would pursue careers in an environmental field.

SHSM director and environment club leader Chris Drummond said he has worked with the RVCA before, planting endangered butternut seedlings in another part of the outdoor education centre and installing several turtle habitat sites.

The trees were paid for by the RVCA’s charitable arm, the Rideau Valley Conservation Foundation.

The RVCA manages the Rideau River watershed. It monitors flood risks and other hazards, regulates development around waterways and supports stewardship activities like tree planting and shoreline naturalization to make the watershed more resilient. It also maintains 11 conservation areas and 42 kilometres of public trails.

You can support the RVCA’s work through a charitable donation to the foundation (www.rvcf.ca), purchasing a tree for a special occasion or donating private land for preservation.

May 7, 2019 – Your mother gave you the gift of life, and now you can return the favour.

Thanks to the Rideau Valley Conservation Foundation’s special occasions tree planting program, you can skip the grocery store bouquet and plant an environmental legacy in your mom’s honour, instead.

The trees are planted across the Rideau Valley watershed, from Frontenac to Smiths Falls to downtown Ottawa, helping to fight erosion, manage floods and keep contaminants out of our rivers and lakes. Staff tend to the new trees, helping them grow into maturity so they can thrive for decades – much like your mother did for you.

A single tree costs $25, while a small grove of five is only $100. Ten trees costs $150 and a family grove of 25 trees costs $250 – just $10 a tree.

Online ordering makes it easy and fast. Under the RVCF’s Special Occasion Trees program, simply enter your donation amount and your information, and you’ll receive a charitable tax receipt to your inbox right away. You can even send your mom an e-card right from the foundation site.

The foundation is a registered charity that supports the work of the Rideau Valley Conservation Authority, which monitors more than 4,000 km² of waterways across 18 municipalities in Eastern Ontario.

The authority is responsible for monitoring water quality, flood risks and other hazards to keep people, property and the environment safe. Planting trees is an important part of the authority’s efforts to promote biodiversity, protect our drinking water and reduce the risk of flooding.

The RVCF plants a combination of white cedar, white pine, red oak and sugar maple.

May 6, 2019 —A FLOOD WATCH is being maintained for properties around Bobs Lake and Christie Lake.

Water levels on both lakes continue to decline slowly but both 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 between 20 mm and 35 mm of rain could fall later this week. 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 Monday May 13, 2019 at 5 PM and will be updated at that time unless the forecast or conditions change.

May 3, 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 model outputs from the Ottawa River Regulation Committee (ORRC) indicate that water levels have peaked on Lac Coulonge and are expected to begin rising again over the next few days. Along the Ottawa River below Lac Coulonge, levels are expected to remain stable or slowly decline over the next few days in all locations. 

All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk as snowmelt from the upper Ottawa River basin begins to move through the system.

Levels will remain high for at least the next week but are expected to decline slowly based on the current weather forecasts.  Risk is highly dependent on the amount of precipitation received over the next two to three weeks.  Residents are strongly urged to keep sandbags in place for at least the next two weeks.

MVCA areas of concern: 

Water levels in the Constance Bay area have peaked and have begun to recede.

RVCA areas of concern:

Water levels in Britannia area (Grandview Road, Britannia Village, and the Belltown Community) and the area east of Cumberland Village (Boise Village, Morin Road, Leo Lane) have peaked and begun to recede.

SNC areas of concern:

Water levels in Clarence-Rockland and Alfred-Plantagenet have peaked on Wednesday, May 1, 2019 and have dropped over the last 48 hours.

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 Tuesday, May 7, 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.

May 1, 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 model outputs from the Ottawa River Regulation Committee (ORRC) indicate that water levels have peaked on Lac Coulonge.  From Chats Lake down to Hawkesbury/Grenville, levels have stabilized but are expected to increase due to forecasted rain of 15 to 35 mm on a large part of the basin starting today.

All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk.

Peak water levels across many areas of the Ottawa River will exceed those experienced in May 2017 over the next couple of days. Levels will remain high and are forecasted to peak between Thursday and Friday. Risk is highly dependent on the amount of precipitation received.

MVCA areas of concern: 

Water levels in the Constance Bay area have exceeded those levels reached in May 2017. The ORRC currently forecasts water levels to rise an additional 0.30 m to 0.50 m above the 2017 levels. Updates to this projection will be provided as they become available.

RVCA areas of concern:

Water levels in the Britannia area (Grandview Road, Britannia Village, and the Belltown Community) have exceeded those levels reached in May 2017. The ORRC currently forecasts water levels to rise an additional 0.30 m to 0.50 m above the 2017 levels. Updates to this projection will be provided as they become available.

Water levels east of Cumberland Village (Boise Village, Morin Road, Leo Lane) are equal to those levels reached in May 2017. The ORRC currently forecasts water levels to rise an additional 0.20 m to 0.40 m above the 2017 levels. Updates to this projection will be provided as they become available.

SNC areas of concern:

Water levels in Clarence-Rockland and Alfred-Plantagenet have risen 0.03 m over the last 48 hours. Levels are forecasted to rise an additional 0.2 m and peak tomorrow, Thursday, May 2. Water levels are expected to be 0.2 m higher than the May 2017 flood.

Due to the forecast uncertainty it is difficult to accurately predict how quickly water levels will rise and when river conditions may peak.

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.

The most recent model outputs from the Ottawa River Regulation Committee (ORRC) indicate that runoff from snowmelt and precipitation is decreasing from Mattawa to Lac Coulonge with levels stabilizing in Mattawa and Pembroke.

The Lower Ottawa River water levels are increasing due to upstream spring runoff caused by rainfall, saturated soil and snowmelt over the central part of the basin. Runoff from ongoing snowmelt and recent rainfall has swollen most of its tributaries.

Rainfall amounts of 20 – 40 mm are forecast for Wednesday and into Thursday. An additional 10 – 20 mm of rain is possible Friday.

All flood-prone areas along the Ottawa River from Lac Coulonge down to the Montreal Archipelago are at risk.

Peak water levels across many areas of the Ottawa River will exceed those experienced in May 2017 over the next couple of days.
