Water clarity map
How does water clarity vary across the country?
Clear water means more sunlight is getting through - which is important for the survival of many plants and animals. If the water is murky or not so clear, then some plants or animals may not be able to live there.
The Opalometer provides a good measure of water clarity. The higher the score, the clearer the water. See Activity 1 in the water survey field guide to learn more about the Opalometer - water survey field guide (PDF, 1.8MB).
