Reading it

• Bathing waters are coloured by today's verdict: red don't swim, amber take care, green no warnings, hollow means something could not be checked.
• Waterfalls are blue, darker for more flow after recent rain. They carry no water quality information at all — nobody tests them.
• Storm overflows shows the monitored outfalls within 2km of a bathing water, red where one is discharging right now.
