Flood Warning Extent Reduced
Water levels have continued to recede over the weekend and are not expected to be affected significantly by rain forecast for later this week. This has led to a reduction of the coverage of the Flood Warning. The Flood Warning is now limited to the upper Tay River where outflow from Bobs Lake has continued but there has yet to be a significant drop of the water level. Several properties around Christie Lake are still flooded. Sections of the Christie Lake North Shore Road has been under water for several days. Flow of the Tay through Perth is declining slowly…

Flood Watch Terminated For Rideau Watershed
Rain forecast for Sunday and Monday can be expected to cause levels throughout the watershed to turn upward; however, no flooding is expected. Rain, possibly 20 to 25 millimetres, can be expected to raise levels in watershed rivers and lakes but not to flood stage similar to what occurred last weekend. Level and flow increases are expected to last for two or three days before returning to gradual declines toward long term averages. With water levels declining and no flooding expected, the Flood Watch, maintained over the last week for the Tay River, is terminated. Conservation Authority staff will continue…

Rain Causing High Flows on Tributary Streams
Heavy rain that has fallen on the Rideau River watershed over the last week has caused some smaller streams to overtop their banks.Rainfall on July 1 was varied over the watershed with 42 millimetres measured at the Ottawa Airport, 31 mm at Franktown in the upper Jock River watershed but less than 10 mm in Kemptville and Westport.Flooding is not expected on the Rideau or the major tributaries, Tay and Jock Rivers and Kemptville Creek. However, safety is an issue around smaller streams that have fast flows with wet and muddy banks, for example, Stevens and Sawmill Creek. Parents need…

Flood Warning Withdrawn for Lakes on Tay River
Water levels are finally receding on Christie and Bobs Lakes both of which have had high water since the two bouts of heavy rain three weeks ago.Bobs Lake levels were high from the spring runoff in April. The rain recorded at Bolingbroke, about 90 millimetres over the four days from May 4 through 7, was similar to what fell over much of the eastern parts of Ontario. The increase of Bobs lake levels made it necessary for Parks Canada staff to release water through the Bolingbroke Dam. Christie Lake has been the unfortunate recipient of the excess water from…

Above normal rain has received plenty of attention over recent weeks with close to a normal month worth of rain having fallen at several monitoring locations in the Rideau watershed in half the month of July. Most extreme is at the Ottawa Airport where 109 millimetres (mm) has fallen to date where 92 mm is the 30 year historical average. Normal precipitation on the watershed to mid-July is about 504 mm. This year, an average of 729 mm has been recorded. After relatively high spring levels in April on Rideau watershed streams and lakes, rainfall has continued to keep levels…

Heavy Rains Forecast in Rideau River Watershed
Heavy rains forecast for Monday into Tuesday could cause rapid increases in water levels in small streams and raise rivers and lakes to above normal levels. The Meteorological Service of Canada (MSC) has issued a Rainfall Warning that says “A slow moving upper disturbance over Lake Huron is expected to generate significant rainfall amounts over much of Eastern Ontario”. As much as 100 millimetres (mm) of rain is possible over a wide area. A few days without rain provided some capacity for infiltration of the rain into the soil but that storage has been filled with water levels already on…

Flooding has occurred in areas of the Rideau Watershed as a result of rains that were closer to monthly totals than daily amounts. The community of North Gower has had floodwaters in some homes and in the streets near Stevens Creek. Low-lying areas along the Rideau and its tributaries have also been flooded but no residential flooding has been reported or is expected in those areas at this time. A weather system moving into eastern Ontario Wednesday night may bring more rain in thunder storms. What impact these storms will have will depend on timing, intensity and size. The decline…

Floodwaters Receding Slowly
As Stevens Creek levels slowly decline, residents of North Gower continue to deal with water in basements and on streets as a result of record setting rainfall. On the Rideau, minor flooding of low-lying areas on the Long Reach have access issues similar to what often occurs in the spring. Parks Canada staff are doing strategic dam operations to get water levels down throughout the Canal system with as little impact as possible. With high flows passing through the dams, boaters are advised to stay well away. Also with high waters, boat wake becomes a problem causing damage to shorelines.…

With relatively minor rain forecast for the coming week and the flood waters in decline, the RVCA is withdrawing the Flood Watch that has been in effect for the last week. Water levels are still above normal but continuing to decline. The 3-day rainfall of 35 millimetres presently forecast for Wednesday through Friday in eastern Ontario is expected to cause a pause in the decline. Periods of heavier, localized rain may fall in thunderstorms but no significant impact is expected at this time. Waters have receded from the North Gower area where serious flooding along Stevens Creek occurred last week.…

Water Levels to Rise with Fall Rains
Heavy rain forecast for today and overnight are expected to cause elevated water levels throughout the Rideau River watershed. With very little rain through September and October, flows on the Rideau system had fallen below the long term average for the time of year. As much as 100 millimetres of rain have been forecast for the next 24 hours. This amount of rain can be expected to raise water levels throughout the system. With the Rideau Lakes at winter levels, it is anticipated that there is capacity to accommodate the rain in the upper watershed with little impact. In the…

More Rain Forecast for Sunday
November 3, 2017 – Rain forecast for Sunday could raise water levels again. In the order of 25 to 30 millimetres of rain fell on the Rideau watershed yesterday and this morning, less than was forecast. The rain was not enough to raise water levels significantly. Rain now forecast for Sunday has the potential to be enough to raise the already elevated flows. Ministry of Natural Resources and Forestry meteorologists have forecast 10 to 25 mm of rain on Sunday which could increase to a total of 40 to 75 mm if thunderstorms occur on Sunday night. The result…

Minor Flooding of Low-Lying Areas the Result of Heavy Rains
Rainfall over the last three days from 70 to 100 millimetres has caused water levels typically seen in the spring in the Rideau watershed. Flows rose dramatically from what they were going into the weekend after very little rain through September and most of October. Operation of the Long Island Dam by Parks Canada staff slowed the increase of levels on the Long Reach. However, access roads to communities on the Rideau near Kemptville may still be threatened as the water from upstream passes through the system. In Perth in the Tay Subwatershed, flooding has so far been limited to…

The RVCA is pleased to offer resources to teachers interested in promoting spring water awareness.
As the warmer spring weather approaches, snow and ice begin to melt and waterways begin to fill up with cold, fast moving water. Children are often interested in exploring rushing streams and thawing ponds during the warm days of spring. However, these areas can be unsafe and it is important to teach students the dangers of these areas.
Resources include:
- Background information about spring flooding
- “Safety Says” video with teacher notes
- Activity ideas, resources, and sheets for use by classroom teachers
- General curriculum information
- Announcement information for use during the spring season
- Information for students to take home during flood season
- Posters
- Dam safety resource materials from Ontario Power Generation
