- Contact Tyler Bauman, Water Resources Engineer (Flood Management)
In cooperation with local municipalities and the province, the RVCA identifies, studies and maps natural hazard areas along local rivers, lakes, streams and wetlands. Natural hazard areas include floodplains, unstable slopes. Natural features such as wetlands are also mapped. In the past, these maps were called flood risk maps.
If not understood or dealt with effectively, these hazards can pose risks and problems to society, especially when considering development activities.
Hazard mapping is used by watershed municipalities when updating Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. The RVCA uses the mapping for the administration and enforcement of regulations made under the Conservation Authorities Act (Section 28).

Streamflow and water level data are used to monitor flood and drought events. They are also used to monitor water supply for lake operation and navigation. This information is used to determine flood risk, support land use planning, assess fish habitat and for water quality analyses of contaminant loading.
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.
The RVCA has gathered information on surface water quality since the early 1970s. Today, the RVCA collects data four water quality monitoring programs:
- Provincial Water Quality Monitoring Network (Water Chemistry)
- RVCA Baseline Monitoring Program (Water Chemistry)
- Watershed Watch (Water Chemistry)
- Benthic Invertebrate Sampling (Water Biology)
Results from these monitoring programs are reviewed and reported on through our catchment and subwatershed reports.
Current Water Conditions Statements
(flooding or drought conditions)
Water plays a central role in all activities within a watershed. The rain that falls on the ground flows to the river and sustains all forms of life. All physical and biological activities within a watershed are intimately connected to water. Therefore, the knowledge of its occurrence, distribution, movement and functions is indispensable in understanding a watershed and all the living beings therein.
Within the Rideau Valley, water levels and stream flow, precipitation and snowpack have been systematically recorded for many years.This information can be analyzed to understand various aspects of the water cycle (or hydrologic cycle) and their impacts on the watershed. Monitoring streamflow and precipitation allows water managers to identify risk-prone areas and better respond to drought or flood conditions.
