Thames WaterBlitz: 25th- 28th September 2020

Registration is now open for the next Thames WaterBlitz between 25th - 28th September

The Thames WaterBlitz is an event held in spring and autumn where volunteers in the Thames Valley collect as many water quality samples as possible. The purpose is to get an overview of the water quality in lakes, ponds and streams throughout the Thames Valley.

Along with data collected by CEH and data held by the Environment Agency continued Thames WaterBlitz efforts complement monitoring by providing information from areas and water body types that would otherwise not be monitored. WaterBlitzes are also a fun learning experience for any volunteer that is interested in their local environment, and would like to learn more about water quality.

Making the 10th WaterBlitz count

This year, the WaterBlitz is co-ordinated with the Riverfly Partnership. Their trained network of anglers will collect data on the invertebrates that live in our waterways at exactly the same time as this survey is conducted. This will allow  for more detail the impacts that pollution, drought, and land use change might be having on our wildlife. If you work with trained Riverfly volunteers, please get in touch!

Please email if you have any questions. We hope that you’ll be able to join us for the WaterBlitz again and help us to make it another successful event!
