Collecting Inventories and Environmental Data
We collect environmental data to:
The data are used to determine the overall health of the watershed’s natural systems and identify trends of concern.
The data are used to reinforce an understanding of local biodiversity richness and inform protection actions.
The data are used to determine if we meet project goals, and to inform future restoration projects.
Our monitoring and inventory initiatives are a collaboration between CVC and our member municipalities, particularly the Region of Peel.
Real-time Environmental Monitoring
We operate a network of 57 real-time environmental monitoring stations throughout the Credit River Watershed. Stations send information in real-time on current environmental conditions. This allows us to better understand, predict and warn about flooding, threats to water quality and low water levels. We share data with our municipal partners to support flood forecasting and decision making.
We monitor a number of key environmental variables, including:
- Water level
- Wind gusts
- Humidity and relative humidex
- Barometric pressure
- Air temperature
- Water temperature
- Dissolved oxygen
- Conductivity and chloride
Our real-time environmental monitoring stations are located throughout the Credit River Watershed.

Integrated Watershed Monitoring Program
The Integrated Watershed Monitoring Program (IWMP) is a long-term monitoring program that reports on the health of ecosystems in the Credit River Watershed.
Long-term monitoring allows us to understand how healthy our watershed is, and whether conditions in our ecosystems are improving, deteriorating or stable. This information informs water and land management decisions. This helps us and our partners develop longer-term strategies to protect and enhance the watershed’s natural resources. We follow rigorous protocols established by federal and provincial agencies based on the best available science.
We monitor living and non-living attributes in:
- Groundwater levels
- Groundwater chemistry
- Water quantity
- Surface water temperature
- Water chemistry
- Stream stability
- Aquatic invertebrates
- Soil conditions
- Tree health and dead wood
- Tree health and dead wood
- Frogs and toads
We also monitor drivers that shape ecosystems:
Data are collected at regular intervals to provide current snapshots of conditions and trends over time.
Our monitoring stations are located throughout the Credit River Watershed.
We publish reports and studies and factsheets about our Integrated Watershed Monitoring Program.

Natural Heritage Inventory
We identify significant natural heritage features and functions in the Credit River Watershed. We collect data on what species and plant communities are present, and how they are distributed.
Our efforts to protect and restore watershed ecosystems rely on inventory data. These data inform:
- Land management
- Natural Heritage System development
We inventory natural areas, from lush old forests and swamps to open meadows, marshes and shallow aquatic areas. We inventory and map:
- Vegetation communities
- Plant species
- Breeding bird species
- Breeding frog species
- Bat species
Our work is done all over the watershed. We inventory in new places every year. We work on both public and private properties, where we have permission from the landowners.

Infrastructure Performance and Risk Assessment Program
We work to understand the long-term performance and life-cycle management of low impact development and stormwater technologies. We monitor stormwater designs and configurations in various land use types and climate conditions.
This program supports municipal partners to ensure compliance with requirements. We share knowledge and expertise by collaborating with the Sustainable Technologies Evaluation Program (STEP). We coordinate our research activities and facilitate knowledge transfer and training.
We monitor a number of key items, including:
- Flow and water balance
- Complex water quality
- Infiltration, soil and groundwater
- Site conditions (through inspections and surveys)
Through this program, we provide support for life-cycle and asset management to our partners.
