Water Survey – join in now

Cymraeg

The best time to do this survey is from May to November.

How healthy is your local lake or pond?

By taking part in the survey, you’ll help scientists learn more about how polluted our lakes and ponds are – something we know surprisingly little about.

Good water quality is essential for the many animals and plants that live in and around our lakes, ponds and rivers. Unfortunately, water is easily affected by pollution from agriculture and industry, waste we throw away, and even pollutants in the air.

Look for clues in the water

Animals living in the water can tell us a great deal about how polluted the water may be. Some species struggle to survive in polluted waters, while others are more tolerant.

By telling us what you find in your local pond you’ll discover
more about the water's health and contribute to valuable
scientific research.
