OPAL Water research data

How healthy are our lakes and ponds?

OPAL monitored the health of nine lakes and ponds across England, looking at water quality, how it's changing, and how the plants and animals are being affected.

We collected physical, biological and chemical data at three-month intervals to explore how things changed over time, research which is being used to help the conservation of ponds and lakes.
