Bio-manipulation to restore clear waters of Norfolk Broads

Conservationists plan for removal of excess algae in two of the region's lakes

It was once famed for its gin-clear waters but today the waterways of the Norfolk and Suffolk Broads are more typically a murky greeny-brown.

Now a new "bio-manipulation" project aims to restore clear waters to Ranworth Broad and Barton Broad, paving the way for the return of osprey, common terns and rare aquatic plants currently thwarted by the murky depths.
