Just turn over a stone to see how your waterways are doing.
Find a stone about the size of your hand and turn it over to see what bugs are lurking.
Compare what you find against the images below – scroll across to see them all.
- If you find bugs from all sections or at least one from the green ‘Very Good Water’ cards – fantastic – the water is very clean.
- If you find none from the green section but at least one from the orange ‘Good Water’ cards then the water is doing OK – but could be better.
- If you only find invertebrates from the red section – there is a pollution problem. Have a look at our page on what to do next.
Never wade more than ankle deep. Never go in during a flood. Children should be supervised. Always wash your hands afterwards.
