Our rivers are shaped by cycles of extremes. At the headwaters of the Thames (which we call the Infant Thames), we are familiar with the impacts of both heavy winter rainfall and dry summer periods, from flooded fields and swollen streams to low flows, warmer water temperatures and likely stressed wildlife.

This summer has already been a reminder of how quickly conditions can change. After a dry spring, rainfall has remained limited, leaving many streams running low and increasing pressure on both wildlife and water resources. With the possibility of water restrictions, including a hosepipe ban, in the coming weeks, it is a timely reminder of the importance of protecting our rivers.
While a dry summer can bring opportunities to enjoy and explore our rivers, it can also place pressure on the freshwater ecosystems that depend on healthy flows. Small headwater streams are particularly vulnerable, with reduced water levels, higher temperatures and less capacity to dilute pollutants. During periods like these, we are reminded just how vital fresh, clean and cool water is, not only for wildlife, but for the resilience of our rivers and the communities which depend on them.
These challenges highlight why understanding and protecting our rivers throughout the year is so important. The work of the Infant Thames Programme is helping build a clearer picture of the health of our local waterways through community monitoring of water quality, river flows, biodiversity and pollution pressures. By gathering regular observations, volunteers are providing valuable information that helps identify problems and guide future action.

We are delighted that this work is growing thanks to recent funding successes. Support from the National Lottery Community Fund and the King Charles III Charitable Fund will help us expand the Infant Thames Programme, bringing together more communities, volunteers and partners to better understand and improve the health of the river.
However, this work depends on people getting involved. Whether you are interested in water quality testing, spotting wildlife, measuring river flows, helping at events, or simply learning more about your local stream, there is a place for you. We are always looking for new volunteers to join the growing community of people caring for the Infant Thames.
