Rideau Canal - Water Level Management Update – April 8, 2024
Parks Canada's water management team continues to actively monitor water levels, flows, and weather forecasts across the Rideau Canal National Historic Site of Canada. These factors are used to determine dam operations on a daily basis for the Rideau Canal National Historic Site of Canada.
Parks Canada maintains the Ontario Waterways Water Management InfoNet on the Rideau Canal website at https://parks.canada.ca/lhn-nhs/on/rideau/info/infonet
The InfoNet contains background information on water management practices, water management updates, frequently asked questions about water management, various reports on water management, and the most recent water levels of lakes along both the Rideau Canal and the Trent-Severn Waterway. The information comes from hydrometric gauges located at key points along both waterways and is vetted by trained and experienced Parks Canada water management staff.
This information is intended as supplemental information only. Your respective Conservation Authority continues to serve as the primary source for relevant flood forecasting information specific to your area. These are the Rideau Valley Conservation Authority and the Cataraqui Conservation Authority.
Weather
Last week, the passage of a Colorado Low resulted in a significant amount of precipitation amounting to 15-46 mm across all watersheds. The 5-day forecast suggests an estimated 30 mm of rainfall this week. Air temperatures are forecasted to rise this week where the daily high will be in the double digits.
Outlook
The current conditions indicate that water levels will increase due already saturated conditions across the watersheds. The current forecast indicates that water levels and outflows will increase at most locations.
The Rideau Water Management team will be actively monitoring the changing conditions. Any watershed conditions updates will be released by your Conservation Authority.
Cataraqui River
All lakes are above the average water levels for this time of year. The outflows are increasing.
Tay River
Bobs Lake level is above the average due to earlier than normal snowmelt. Christie Lake levels are below average but increasing due to recent precipitation event and increased outflows from Bobs Lake.
Rideau River
Upper Rideau and Big Rideau Lakes are near average for this time of year. Wolfe Lake levels are above average. The river reaches between Smiths Falls and Long Island are currently subject to operations in anticipation for the increased flows generated by rain runoff. The flows on the River are below average and expected to increase.
