April 11, 2018 – A weather system out of the mid-west U.S. has the potential to bring several forms of precipitation in significant amounts in to eastern Canada over the next week.

Snow, rain and freezing rain may fall beginning tonight with showers or flurries. Tomorrow, rain is forecast to fall through the afternoon. Rain is expected to begin again late on Friday morning and continue into Saturday, changing to snow in the early morning finishing with as much as 20 centimetres. Rain is presently expected to resume on Sunday and continue into Monday.

If the full amount of forecast precipitation falls, there is the potential for minor flooding to occur in the Long Reach of the Rideau near Kemptville. The lower lying communities in that area may have access issues.

Water levels throughout the watershed are below average for the time of year so there is capacity to accommodate some of the runoff with little impact. Cooler than normal temperatures are forecast which could mean that the runoff process will be slowed to an extent with freezing temperatures overnight. Temperatures closer to spring-like are not expected until the end of next week.

This weather system has the potential to develop into a more significant event over the next five days. RVCA staff will continue to monitor and further statements will be issued if conditions warrant.

Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Streambanks are slippery and any remaining ice cover on streams, ponds and lakes will be hazardous. Parents are advised to keep their children and pets away from all watercourses as levels fluctuate with the spring weather.

April 3, 2018 – Rain in the order of 20 millimetres is forecast for today and into the night that will cause water levels throughout the Rideau valley to increase beyond levels reached after rain on Saturday.

How much levels increase will be limited by dropping temperatures and the changeover from rain to freezing rain or snow overnight and tomorrow. Peak flows from this weather are still expected to be less than average for the spring freshet. These may not be the actual freshet maximum flows.

The Long Reach of the Rideau River, between Manotick and Kemptville, could have levels over the banks as a result of the rain but access is not expected to become a problem in the small river side communities such as Hilly Lane and Cedar Beach.

Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which have been weakened as a result of the warming conditions.

 RVCA will continue to monitor conditions and will issue further statements when or if there is an indication that the situation can be expected to change significantly.

March 29, 2018 –  Barring a rain event not presently in weather forecasts, it is appearing that the spring freshet of 2018 in the Rideau valley may have already occurred on March 2 as a result of the above normal temperatures in the latter half of February that removed all of the snow.

The snow that fell after the early March thaw, has gradually declined over the month with several sunny days and above freezing daily temperatures. With little snow and minor rainfall forecast, there is not expected to be enough runoff to cause significant increases in water levels in the Rideau valley. A flow in the order of 115 +/- cubic metres per second (cms) is possible at the monitoring station Rideau River at Ottawa if the weather that is forecast for the next four days arrives. That would be less than 50% of the long-term average spring flow.

Such a flow would cause flooding of only the lowest lying shoreline in the watershed but no residential flooding. Still, waterfront residents are advised to secure any of their possessions that could float away and ensure that sump pumps are operating properly.

Colder temperatures and snow are forecast for next week which will prolong the passing of the freshet but there is nothing indicated that would raise levels significantly.

March 27, 2017, EASTERN ONTARIO — The Rideau Valley Conservation Authority (RVCA) Board of Directors celebrated World Water Day with release of their 2017 Annual Report. The report highlights the many achievements and on-the-ground projects that happened throughout the over 4,000 square kilometres of the Rideau watershed — activities that focus attention on the importance of water and supports World Water Day values.

“RVCA is committed to supporting watershed health and the principles promoted through World Water Day,” said Sommer Casgrain-Robertson, RVCA General Manager. “It is fitting that we release our 2017 Annual Report on this special day and share how RVCA and its many partners are working to support human health and well-being through sound management and protection of the natural systems around us.”

World Water Day 2017 looks to nature-based solutions to help solve many of our water challenges. The challenge is to do more with ‘green’ infrastructure wherever possible. Planting new forests, reconnecting rivers to floodplains, and restoring wetlands will rebalance the water cycle and improve human health and livelihoods. These globally endorsed concepts and principles are fully supported by the RVCA and guide its local conservation work.

RVCA and its many partners (municipalities, farmers, property owners, conservation groups, businesses and academia) recognize the value of water and the benefits of nature. RVCA looks to protect the health of the Rideau watershed and the people who live in it through environmental monitoring and reporting, on-the-ground restoration and stewardship, conservation lands and education, development review and approval and flood forecasting and warning.

“Without natural features like forests and wetlands, we wouldn’t have clear air to breathe, clean water to drink, rivers to boat, swim and fish in, water and soil to support agriculture and industry and green spaces to explore and relax in,” said Ms. Casgrain-Robertson. “Simply put, nature sustains life.”

Highlights for 2017 include:

• $752,192+ in grants distributed to landowners who undertook stewardship projects
• 274,550 trees planted (5.97 million planted since 1984)
• 200,000 visitors to conservation areas annually
• 10,200+ students experienced RVCA Outdoor Education Programs
• 9,700 trees and shrubs planted along shorelines through RVCA’s Shoreline Naturalization Program
• 3,000 hectares of conservation land protected and managed
• 1,191 hours from 262 volunteers invested in Ottawa’s City Stream Watch program to research and clean up city streams
• 1,187 Planning Act applications received (minor variances, site plan control, subdivision applications, etc.)
• 628 applications for new or replacement septic systems received
• 380 hours donated by 25+ volunteers to help monitor and sample Watershed Watch lakes
• 348 septic re-inspections completed in participating municipalities
• 300 applications received for work along wetlands, shorelines and waterways (Section 28, Conservation Authorities Act)
• 42 kilometres of trails maintained for public use at local conservation areas
• 40 flood forecasting and warnings messages issued in 2017
• 39 lakes and 58 river and stream sides monitored for nutrients, E.coli and other parameters
• 16 wells monitored for ground water quantity and quality
• 6 invasive species removals and 5 stream clean ups on tributary streams in Ottawa
• release of the Jock River Subwatershed Report and 12 Jock catchment reports
• posting of 6 subwatershed reports and 66 catchment reports online at watersheds.rvca.ca

“Today’s investment in local water and watershed health will ensure a sustainable future — one that supports local communities, economies, tourism and recreation,” said Ms. Casgrain-Robertson. “Thanks to everyone who helped us achieve our 2017 goals and we look forward to continued support and success in 2018.”
