The Mississippi Valley and Rideau Valley Conservation Authorities administer Part 8 (Sewage systems approvals) of the Ontario Building Code on behalf of watershed municipalities (listed below). This means your local conservation authority is responsible for reviewing septic designs and plans, issuing Building Permits for new and replacement sewage systems, and inspecting installations to ensure compliance with provincial regulations. 

Learn more on how to submit your application by choosing the municipality where you are installing or replacing a Part 8 sewage system. Not listed below? Check with municipality to learn about their septic approvals agent.

RIDEAU VALLEY, June 10, 2022 – A new network of industrial weather stations will advance the Rideau Valley Conservation Authority’s capacity to track local weather, model future floods and track local climate change impacts into the future. 

The RVCA has installed 11 new all-season weather stations across the watershed. These will fill gaps in the current data network, expand RVCA’s list of tracked weather parameters and provide real-time weather data online for use by residents, municipalities, farmers, researchers and even local forecasters. 

“Our goal is to develop a watershed-wide model so we understand what’s happening in each part of the watershed,” said Brian Stratton, RVCA’s manager of engineering. “The new weather stations are a key piece in the development of a long-term model that can be used for hazard mapping, flood forecasting and tracking climate change trends.”

The industrial-strength stations – designed to withstand our coldest winters and hottest summers – will collect information on air temperature, dew point, relative humidity, air pressure, solar radiation, average wind speed and precipitation. The data is available through a new public portal on

The addition of these stations will also improve Environment Canada’s ability to provide accurate weather forecasting for the region, as data from RVCA’s new stations will help corroborate what Environment Canada’s radar is predicting. 

“It’s a nice relationship,” said RVCA’s hydrometric co-ordinator Justin Robert. “We’ve programmed these stations for our own purposes, but everyone in the watershed will benefit.”

Climate researchers will also rejoice – in 30 years, anyway.

“By recording the real time climate, it’s going to set us up for some extensive knowledge down the road,” Robert said. “These weather stations are going to give us this footprint of our weather into our future, and it will be invaluable information to really understand our watershed and what’s going on.”

New weather stations are located in: Andrewsville, Bobs Lake, Frankville, Kars, Mansfield, Marlborough, Montague, Motts Mills, Rainbow Lake, Snowdons Corners and Westport. For more information contact Brian Stratton at


OTTAWA, June 7, 2022 — The Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Mosquito Creek from Mitch Owens Road to the Rideau River, in and around the community of Riverside South. Members of the public are invited to an upcoming open house to review regulation and hazard maps. 

Much of the area has been regulated since 2017 when hazard mapping was completed for the Rideau River from Hogs Back to Kars (Rideau River Flood Risk Mapping Report from Hogs Back to Kars, July 2017). This 2017 mapping captured Mosquito Creek from the Rideau River to Limebank Road. This new study reviews past mapping and extends upstream from Limebank Road to Mitch Owens. 

The new mapping shows areas that are subject to natural hazards such as flooding and unstable slopes and have natural environmental features such as wetlands. The mapping will be used by the City of Ottawa when updating Official Plans and Zoning Schedules and in the review of development applications under the Planning Act. RVCA will also use the mapping to guide the review of development applications submitted under the RVCA’s Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.

The goal of this mapping is to help ensure that sound planning decisions are made — keeping people and property safe. Accurate engineered hazard mapping is the foundation of effective floodplain and resource management.

Members of the public are encouraged to attend the open house and/or provide comments on the mapping. The RVCA also welcomes every bit of information that we can obtain about the historical behaviour of local watercourses. Residents and landowners living along these features may have anecdotal or documented information such as photographs or journal entries of their observations during past high-water events or slope failures. 

Mosquito Creek Hazard Land and Regulations Mapping Public Open House
Rideauview Community Centre
4310 Shoreline Drive, Ottawa
Tuesday, June 28, 2022
4:30 to 8:00 p.m.

For those unable to attend the open house, mapping can also be seen online at Individual or small group meetings (on-line or in-person) can also be booked by contacting an RVCA Resource Specialist at  or by completing an online property inquiry form at 

The public consultation period will run until July 29, 2022.

This study is being done through a collaboration involving the City of Ottawa and the Rideau Valley, Mississippi Valley and South Nation Conservation Authorities. The City recognized a need to update its zoning schedules based on up-to-date hazard mapping and has provided contributions enabling the Conservation Authorities to move ahead with these studies sooner than would otherwise be possible. The RVCA is currently working on several studies in the Ottawa area. For a complete list of ongoing work, please visit

OpenHouseMapMosquitoThe Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Mosquito Creek from Mitch Owens Road to the Rideau River in the City of Ottawa.

Much of the area has been regulated since 2017 with the completion of the report entitled: Rideau River Flood Risk Mapping from Hogs Back to Kars, July 2017. This 2017 mapping captured Mosquito Creek from the Rideau River to Limebank Road. This new study extends to Mitch Owens and will update previous mapping. 

These maps have been traditionally known as “floodplain mapping” or “regulation mapping” and they show areas that are prone to natural hazards such as flooding, erosion and natural environment features such as wetlands. 

When completed, the mapping will be used by the City of Ottawa when updating their Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. RVCA will also use the mapping to guide the review of development applications submitted under the Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.

Members of the public are invited to share information and review the draft regulation and hazard maps (available below) during the public consultation period which will run until July 29, 2022. We also welcome you to see the draft hazard and regulations maps at the public open house.

    LANARK COUNTY, May 13, 2022 – Lanark farmers can access even more stewardship grant options thanks to a new partnership with agricultural stewardship organization, ALUS.

    The new ALUS community, called ALUS Lanark, will facilitate new grassroots, farmer-led natural infrastructure projects in Lanark County, and will be administered by staff at the Rideau Valley Conservation Authority (RVCA) and the Mississippi Valley Conservation Authority (MVCA). 

    While the RVCA currently offers a rural clean water stewardship program on behalf of both conservation authorities, this new partnership will expand the number of opportunities available in Lanark, specifically for agricultural properties. 

    “We’re thrilled to partner with ALUS to expand our stewardship programs for farmers in Lanark County,” says Sommer Casgrain-Robertson, General Manager, RVCA. “We know many Lanark farmers want to enhance their operations for the health of their lands, livestock and the watershed, and this partnership will support them in those efforts and give them even more opportunities to do that.” 

    Home to approximately 60,000 people, the county is a picturesque rural landscape of forests, lakes, wetlands, agriculture, cottages and small towns. The county also has the Rideau River and the Mississippi River passing through it and contains parts of the Canadian shield and the Great Lakes basin, important and unique natural features.

    "Our county is focused on local climate change solutions," says John Fenik, Lanark County Warden. "Supporting farmers in their efforts to improve biodiversity and water quality on their lands is an important part of this strategy and is why we are so excited to partner with our local conservation authorities to bring the ALUS program to Lanark."

    The new program will support farmers in the creation of an array of ecosystem projects, including reforestation, windbreaks, riparian buffers, wetland projects, tallgrass prairie, pollinator habitat and more.

    “Our partnership with the County, ALUS and RVCA is a win for Lanark farmers, the community and the Mississippi watershed,” says Sally McIntyre, General Manager, Mississippi Valley Conservation Authority. “Farmers are frontline stewards of the land, and this program will help them to adapt to changing economic and climatic conditions.”

    These projects will contribute to the health of the farmers’ privately-owned landscape, while also benefitting the broader environment by providing support for biodiversity; reducing downstream flooding in neighbouring communities and ecosystems; and mitigating the impacts of climate change through carbon sequestration and other natural mechanisms.

    “ALUS is so happy to be adding another community in Ontario,” says Alyssa Cousineau, Eastern Hub Manager, ALUS. “It’s clearer each passing year how important a healthy environment is for communities to thrive, which is why we are thrilled to see new communities adopt the ALUS model to help enrich the natural world that we all depend on.”

    ALUS Lanark will be guided in its decision making by a Partnership Advisory Committee (PAC). The PAC ensures that local priorities are addressed by ALUS projects. Fifty per cent of the committee members are local farmers who, in partnership with the other committee members (local elected officials, environmental experts, etc.), will determine which projects are prioritized for the ALUS program.

    About ALUS 
    ALUS (originally an acronym for Alternative Land Use Services) is a charitable organization that sustains agriculture and biodiversity for the benefit of communities and future generations. ALUS provides direct financial and technical support to a network of more than a thousand farmers and ranchers who deliver ecosystem services in more than 30 communities across Canada, such as cleaner air, cleaner water, carbon sequestration, erosion control, flood mitigation, pollinator support and wildlife habitat.
