Monitoring

Here you can find the results of monitoring by volunteer citizen scientists for fly life and water quality.

The map shows where the different types of monitoring take place.

Where do we monitor on the Upper Itchen ?

With our interactive map, you can see where we monitor river health, you can check where the Environment Agency monitors, and you can see pollution sources such as waste water treatment works with the last storm overflows and off-mains drainage such as septic tanks, as well as protected (designated) areas on the Itchen.  Just use the Layers icon to see the locations.
