The extent of turbidity monitoring and methods used on a given construction project should be based on erosion risk, receiving water flows, presence of species at risk, and type and location of discharge points.
The extent of turbidity [[monitoring]] and methods used on a given construction project should be based on [[Erosion#Erosion_potential|erosion risk]], receiving water flows, presence of species at risk, and type and location of discharge points.
{{textbox|The monitoring program for sites applying the receiving water target should include the following components:
{{textbox|The monitoring program for sites applying the receiving water target should include the following components:

*One continuous online turbidity monitoring station 5 to 15 m downstream of the last site discharge point.
*At least one continuous online turbidity monitoring station immediately upstream of the site.}}
*At least one continuous online turbidity monitoring station immediately upstream of the site.}}
Each turbidity monitoring station should be equipped with a turbidity sonde, data logger, power supply, protective enclosure, and, where Species at Risk (SAR) are present, telemetry capabilities. Continuous turbidity monitoring should be maintained until the site has reached at least 80% effective permanent stabilization. Where continuous monitoring is not feasible, grab samples should be collected. To support interpretation of turbidity exceedances, precipitation data should be obtained from a rain gauge located within 5 km of the site. Clear protocols for responding to and reporting turbidity exceedances should be established for all sites with continuous monitoring.
