Save the River Mole

The River Mole is much loved and well used by the communities it passes through on its 80 kilometre (50 mile) journey from Sussex to the Thames.  It is a beautiful amenity for leisure and nature, but sadly the river is polluted from a variety of sources, and fighting for its life. As awareness of the deterioration of our rivers has grown, so has outrage and a determination to take action.  


River Mole River Watch is a coming together of individuals and groups who care about the river, including established groups such as Friends of the River Mole Leatherhead (FoRML), Friends of the River Mole Molesey (FORMM), and new groups springing up in Reigate, Horley, and Dorking.


By working together, we believe that we will be better able to collect and distribute information and data, and campaign for action to improve the situation. River Mole River Watch aims to work with others to return the River Mole to a good ecological state for wildlife, plants and people. We could not operate without the ongoing generous support we receive from, environmental and conservation organisations, water companies, commercial services, local community groups, a parish council, individuals and local, district and county councillors.


Please join us.

In 2022 only 14% of rivers in England achieved 'good' ecological status.
The ecological status of the River Mole is ‘poor’ .
What We Do

Many citizens wish to take action because of the conspicuous failure of government and The Environment Agency to defend our rivers from pollution. Our aim is to co-ordinate the efforts of concerned local citizens to:

  • Regularly test the water quality in the river and its tributaries, and make results known to the community and responsible agencies.

  • Monitor the state of the river, spotting and reporting pollution events and areas of concern.

  • Raise awareness of the state of the river through delivering talks, distributing information, and social media.

  • Work with everyone who can improve the situation, including householders, farmers, manufacturers, business operators, water treatment companies.

  • Hold to account those who have responsibility, in particular the local water treatment company, Thames Water, and the Environment Agency.

  • Campaign to press for action to improve the situation by lobbying politicians, companies and organisations.
