Where are the healthiest lakes? Does water clarity affect what invertebrates you might find? Which pollutants have the biggest impact on aquatic life?

You can now explore these and many more questions with the new interactive maps and graphs in our water survey results section.

We have already received results for more than 2,000 water surveys. Thank you to everyone who has contributed so far.

Please keep taking part and sending in your results - the more surveys submitted, the more valuable our research becomes.
 

Create your own graph to explore how factors such as the pH and pollutants recorded at a site affect the numbers of invertebrates living in the water.
 

Where have the clearest waters been found?
 

The water survey gave every pond or lake an instant health score. Where are the ponds with the best scores?
 

Are some invertebrates more common in certain areas?
