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 could…

Water levels that were already high from rain on Sunday and Monday are expected to increase again if rain forecast for Thursday and Friday falls on the Rideau River watershed.   About 12 millimetres (mm) of rain fell overnight and as much as 40 mm more is expected. This could cause flows in the Rideau below Mooneys Bay to increase to about 320 cubic metres per second. While not an issue in the lower sections of the system, such flows typically mean flooding of low-lying areas on the Long Reach, the section of the river between Manotick and Burritts Rapids,…
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…

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…
OTTAWA, October 26, 2017 — After years of community consultation and long-standing safety concerns, the RVCA is decommissioning the Hearts Desire Weir and beginning work on a new rocky ramp. Work will begin on the project starting October 30 — weather permitting. Located on the lower Jock River near Prince of Wales Drive, the Hearts Desire weir was built in 1975. The goal at the time was to provide higher summer flows, improve habitat for fish, ensure water for livestock and provide community ponds for fire protection and beautification. Since that time, conventional thinking regarding the environmental benefits of weirs…
EASTERN ONTARIO, October 12, 2017 — The Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Kings Creek — a tributary of the Jock River — from the Brunton Side Road to the Jock River. Members of the public are invited to an upcoming open house to review regulations and hazard maps. This study provides new mapping that show areas that are prone to natural hazards such as flooding and erosion and have natural environmental features such as wetlands. The mapping will be used by the City of Ottawa and the Townships of Beckwith and Montague when…

The September-October Issue is now available.  Find it in the Publications section of the website.
MISSISSIPPI-RIDEAU REGION, September 11, 2017 — Staff from the Mississippi-Rideau Source Protection Region (MRSPR) successfully met with 61 business owners in the communities of Westport, Montague, North Grenville and Mississippi Mills this summer to discuss chemical products that could pose a risk to four municipal drinking water systems. Business owners were welcoming and helpful — allowing staff to better understand the chemicals that are being used in wellhead protection areas. MRSPR staff completed this work on behalf of the local municipalities who are striving to meet the requirements of the Ontario Clean Water Act. These outreach projects promote the long-term…
CITY OF OTTAWA AND MUNICIPALITY OF NORTH GRENVILLE, August 21, 2017 — Members of the public are invited to an upcoming open house to review hazard maps. The Rideau Valley Conservation Authority (RVCA) has completed two hazard mapping studies for the Rideau River: Hogs Back to Kars and Kars to Burritts Rapids. These studies update existing mapping in some areas and new mapping in others. Both Rideau River studies look at identifying two main types of hazards along these stretches of the watercourse: flooding and slope stability.  The mapping will be used by the City of Ottawa and the Municipality…
Money is available to landowners interested in planting trees. The Rideau Valley Conservation Authority offers private landowners tree planting programs that help them get technical advice, planting plans and funding for trees.  “We have numerous community-minded partners providing funding to projects to help reduce landowner costs,” says Scott Danford, RVCA Forestry Program Manager. “We offer planting programs that make it easy and affordable for landowners.” To be eligible, landowners need at least one acre of land and are willing to plant a minimum of 500 trees. If you have the space, RVCA can help get trees growing on your land…
On January 17, 2017 the Rideau Valley Conservation Authority downgraded the Drought status in the watershed from “Moderate,” which had been carried over from a dry year in 2016, to “Minor.” The “Minor” status was kept in place because of uncertainty about groundwater conditions that couldn’t be checked until spring. The “Minor” status was removed on April 19 after three months of above normal precipitation that went a long way to recharging groundwater aquifers. Since February, rainfall totals each month have been an average of 1.65 times normal. It is not unusual for there to be above normal amounts of…
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.…
Ottawa South residents and guests can enjoy the soothing sights and sounds of nature along the newly upgraded Chapman Mills Conservation Area trails and boardwalk. Dignitaries and special guests gathered at the site today to celebrate and help with the installation of the final pieces of wooden boardwalk. Owned by the Rideau Valley Conservation Authority (RVCA), Chapman Mills is an exceptional example of conservation parkland with river shoreline, wetland and flood plain areas that are unique and vital to our local community. “Chapman Mills is one of Ottawa’s most ecologically significant natural areas,” said Rideau Valley Conservation Authority (RVCA) Chair…
