OPAL Water Survey

Cymraeg

How healthy is your local lake or pond?

Pond dipping

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.

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 taking part in the OPAL Water Survey you’ll discover more about the health of ponds in your local area.  By submitting your data online, you can use the OPAL Data Explorer to compare your results to others submitted across the UK.

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