The Health Board inspected Lake Harku. There are blue-green algae in the water. Do not swim there.
Warm weather makes the water warm. Blue-green algae grow quickly. Be careful. Pay attention to the signs. Wash your hands and body after swimming.
Water with blue-green algae can make you sick. Young children and animals are at risk. If a child or animal drinks this water, it can be bad. If you feel unwell, call a doctor.
Check the water before swimming. If the water is green and slimy, do not swim. If the water is clear, then swimming may be safe.
