River Restoration Manager/Officer Thames21 – Full Time

We are looking for a committed, self-motivated and technically capable River Restoration Officer or Manager. This position is crucial to delivering the Thames21 River Restoration Mission. In recent years Thames21 has significantly up-scaled our planning and delivery of river restoration works and in 2020/21 we restored 5km of rivers. In the next 5 years we intend to continue to expand this work so that the rivers we work on become dynamic, re-naturalised, rich in ecology and championed by the local community.

Your responsibilities will include: Working with Thames21’s Head of Improving Rivers and local stakeholders such as catchment partnerships, councils, friends of groups etc. to develop and deliver river and wetland restoration projects throughout the areas we work.

Develop detailed plans for the river and wetland restoration in consultation with local and expert stakeholders, meeting local needs and ecological objectives. Ensuring the necessary requirements for Construction, Design and Management (CDM) are covered as part of that process.

Obtain all necessary permissions to deliver the projects, potentially including flood defence consent and planning permission. Ensure that the development and implementation of the works are well integrated into wider programmes such as catchment partnerships, evidencing and community engagement.

Work with project partners to develop and manage tender processes for works which require the use of contractors, the tender processes will need to meet relevant requirements for project partners and funders (including CDM).

Manage contractors to implement projects so they achieve the maximise benefits.

Oxford Rivers Project: Citizen scientist water quality monitor

You can only manage what you monitor. Amazingly, bacteria harmful to human health have not been tested for in the rivers in and around Oxford for decades, either by the Environment Agency or Thames Water. As a consequence, we just don’t know how safe it is to swim in the rivers, when bacteria peaks, or where the major sources of bacteria are coming from.

Thames Water have committed funding and lab space to analyse water samples from 18 locations across the river catchment every month in 2021. However, we need to provide volunteer ‘citizen scientists’ to go and collect these samples – can you help?

There will be four broad ‘zones’ covered by the survey:
1. Stanton Harcourt
2. Farmoor & Eynsham
3. Oxford North & Kidlington
4. Oxford South & Sandford  

Job role:

  • Along with another volunteer, taking river water samples from your ‘zone’ (4-6 sample sites) once a month;
  • Ensuring sterile scientific procedures are followed to collect these water samples;
  • Collecting equipment and delivering samples to Farmoor Reservoir;
  • Reporting to the volunteer coordinator and the volunteer group, via text or whatsapp, to ensure all samples are collected in the correct time frame.


  • Access to your own vehicle;
  • Willingness to follow scientific procedures exactly;
  • Interest in river water quality issues.


  • Visiting some beautiful river locations around Oxfordshire;
  • Being part of vital, groundbreaking research to protect rivers – we are one of the first groups in the country to trial this citizen science method; 
  • Become part of a network of like-minded people who care about rivers, including campaigners, scientists and other academics;
  • Gain experience of environmental science and fieldwork.


One day a month for 6 months.

Full training and support will be provided. The initial training day will be held at Port Meadow, Oxford on Friday 23rd April 2021 – eventbrite sign up here. If you are interested, please email with which zone you could cover and why you would like to take part. 

Oxford Rivers Project: River use surveyors

This role would suit volunteers who cannot give a regular commitment.

To apply for ‘designated bathing water status’, (which, if granted, would mean the river water would be tested every week by the Environment Agency during the summer months), we need to provide data to Defra to show that the rivers in Oxford are very well-used by swimmers. 

To do this, we need to provide numbers of adult and child river users over the bathing season (15th May – 30th September) and the school holidays at popular swimming locations in Oxford (e.g. Port Meadow, Longbridges, Tumbling Bay, Kennington Meadows).

We will be surveying river-users over 20 days in May – September, with the majority of dates in July and August. You could sign up for one day or multiple days. The survey itself should take a maximum 2 hours.

Job role:

  • Alone or with another volunteer, count the river users at a popular bathing location on a designated day;
  • Follow a set procedure and record results accurately;
  • Report results promptly;
  • Communicate with the volunteer group and co-ordinator.


  • Vital contribution to safeguarding Oxford’s rivers for future generations;
  • Become part of a network of people who care about the rivers, including campaigners, scientists and other academics;
  • Access to events, both online and in person;
  • Visiting beautiful Oxford river locations in the warmest months of the year!

Full training and support will be provided. The initial training date is TBC. If you are interested, please email with why you would like to take part.
