Community Watershed Monitoring
What is the Community Watershed Monitoring Network?
It's a partnership between the RDN's Drinking Water and Watershed Protection (DWWP) program, the Ministry of Environment and Climate Change Strategy (ENV), Island Timberlands LP (managed by Mosaic Forest Management), and many amazing community watershed stewardship groups in our region. The RDN provides the equipment and works with ENV to complete annual training and data analysis. ENV contributes expertise in water quality testing, deciphering gathered data and guidance in program direction. Island Timberlands sponsors the lab analysis costs for Quality Assurance and Quality Control, loans volunteers' safety gear and provides access to the upper watersheds. Dedicated community groups donate their time, attending annual training sessions, calibrating equipment and getting out on their local streams to collect and monitor water quality data.

- Why?
-
To expand on the provincial database, collect enough data to see watershed trends and raise watershed health awareness in local communities. The long term objective is to use multiple years of data to determine which watersheds require more detailed monitoring and/or improved watershed management and to assist in land use planning. Data is collected for turbidity, dissolved oxygen, temperature and conductivity for 67 sites in 26 watersheds across our Region. Additional lab analysis has and continues to be completed to further investigate what potential contaminants are associated with water quality exceedances observed in the data collection. In 2014 eleven sites in northern RDN waterways were sampled for E.coli and Phosphorus, in 2015 eleven sites in southern RDN waterways were sampled for E.coli, Phosphorous and metals, and in 2019 with nine sites sampled for Chloride (as a proxy for road run-off) and twelve sites sampled for Phosphorus (as a proxy for agricultural run-off). Further sampling for nutrients is being completed in 2021 in-partnership with ENV in areas with upstream agricultural land-use.
- When?
-
Monitoring occurs once a week for 5 weeks in the summer low flow period (August - September) and once a week for 5 weeks in the fall flush period (October - November).

- Where?
-
There are 41 streams currently monitored by trained volunteers, these include:
- Rosewall Creek
- Cook Creek
- Deep Bay Creek
- Thames Creek
- Nile Creek

After three years of sampling, each site's results are reviewed and testing at sites with consistently good water quality is suspended for three to five years. This allows resources to be used to expand the network, adding sampling at new sites where needed.
