THE RIVER Itchen has turned red.

Over the weekend the water at the Ocean Village Marina turned a deep shade of reddish-brown.

It is believed the sudden change in colour is due to “red tide”.

This is when aquatic plant life becomes highly concentrated and causes the colour of coastal waters to change - also known as algal blooms.

High temperatures are thought to trigger an increase in algae.

The Daily Echo has contacted Southampton City Council and Environmental Health for comment.
