New Story Trail takes families under the snow
WESTPORT, Feb. 19, 2021 – A new story trail adventure at Foley Mountain Conservation Area is bringing new meaning to Ontario’s winter wonderland as families get outside this winter. “Over and Under the Snow” by Kate Messner with art by Christopher Silas Neal brings to life the magical world happening under the snow while teaching kids how different animals survive the winter. From hibernating bumblebees to “tough guy” chickadees, the book “evokes a lot of imagination,” said site supervisor Rebecca Whitman, who is also the lead outdoor educator at the park. “Kids can connect the words to what’s happening in…

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. (See watershed map and table).
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.
NOTE: These maps are for informational purposes only and are not as exact as those used for regulatory purposes.
Please note:
- The 1:2 year return period flood event has a 50% chance of occurring in any year.
- The 1:5 year return period flood event has a 20% chance of occurring in any year.
- The 1:10 year return period flood event has a 10% chance of occurring in any year.
- The 1:20 year return period flood event has a 5% chance of occurring in any year.
- The 1:50 year return period flood event has a 2% chance of occurring in any year.
- The 1:100 year return period flood event has a 1% chance of occurring in any year.
All Rideau River Additional Flood Maps are based on recorded flow at the Rideau at Ottawa [02LA004] gauge, located at Carleton University. The two Grandview Ottawa River Additional Flood Maps are based on recorded flow at the Ottawa River at Britannia [02KF005] gauge. The Boise Village/Morin Road Additional Flood Map is based on recorded water levels at the RVCA Cumberland gauge.
DISCLAIMER: Users of the RVCA flow data and water level data are cautioned to consider the unverified nature of the information before using it for decisions that concern personal or public safety or the conduct of business. The Rideau Valley Conservation Authority assumes no responsibility for the correctness of the information contained in this website nor liability to any user of such information, regardless of the purpose. River levels and flows can change rapidly.

One Tree Planted to support 40,000 new trees in rural Ottawa
OTTAWA, Feb. 8, 2021 – Rural Ottawa landowners can access an additional 40,000 trees thanks to a generous donation from One Tree Planted. RVCA’s tree planting program helps private landowners turn farm fields and other marginal land into thriving forests of the future. This is the second year of support from One Tree Planted, which will transform 20 hectares of idle land into functioning green infrastructure. Forests protect soil from erosion, improve nearby water quality, reduce flooding risks, capture carbon, improve wildlife habitat and increase biodiversity. Environment Canada recommends 30% forest cover in any community to sustain biodiversity and enjoy…

Cold Weather this weekend could cause localized frazil ice formation and flooding in Rideau Valley Watershed
WCS - R02/2021 January 29, 2021 – Environment Canada is forecasting very cold weather beginning today and continuing into Sunday before returning to normal range on Monday. This includes night-time wind chill temperatures in the range of -20 to -30 degrees Celsius. In areas where there is a lack of ice cover along with turbulent flow, these cold temperatures can trigger the formation of frazil ice which can accumulate quickly on bridge abutments, piers and riverbanks resulting in increased water levels and flooding in low-lying areas. The small rivers and streams with open water, such as the Tay River, are…

Lakeshore donation a welcome addition to protected lands
TAY VALLEY, Jan. 28, 2021 – A beautiful piece of Tay Valley shoreline will be preserved in perpetuity thanks to a generous land donation to the Rideau Valley Conservation Foundation (RVCF). The 12-acre swath of forest and wetland is part of a thriving ecosystem and home to countless creatures – some of them currently at risk in Ontario. It is classic grey ratsnake territory, supporting an important species at risk in the Frontenac Arch biosphere. The Eastern wood-pewee, a species of special concern in Ontario, has also been spotted nearby. The property is mostly mixed hardwood forest, with a small…
