Monitoring the health of our rivers
A healthy river system is one with a rich diversity of species and habitats all co-existing in clean water. As well as being somewhere we like to spend time, a healthy river can provide us with clean drinking water, flood retention and many more services important in our day-to-day lives.
Why are rivers important?
The UK has come a long way since the 1970s, when many of our rivers were inhospitable places to both people and wildlife. We now have the cleanest rivers for decades; however, there are still many challenges we face before our rivers will be in a good ecological state again.
What are we doing?
The Trust launched RiverSearch in 2013 to monitor and improve river health on the Wey and Mole catchments. With the help of volunteers, we are assessing and restoring stretches of river across the county to help wildlife thrive in these important habitats.
How you can help
If you would like to take part in monitoring your local watercourse, then please register as a volunteer.
If you are already registered, please email firstname.lastname@example.org to request a Cartographer account. Once you are registered you will be able to submit data to the Cartographer website and see your survey on the map below!
Aquatic invertebrate sampling
Volunteers have the option to train in aquatic invertebrate sampling as part of the Riverfly Partnership. This sampling helps us to monitor water quality by looking at the fly larvae living on shallow river beds.
Once trained, volunteers can join one of the various monthly monitoring groups that have been set up at different points across the catchments or, alternatively, they can create their own group.
River restoration days
The Trust is involved in a large number of river restoration projects which all RiverSearch volunteers will be invited to get involved with. These optional days are a good opportunity to meet other volunteers as well as learn basic river restoration techniques and get hands on.
