Fed by the River Ant, Barton Broad is the second largest of the broads, after Hickling Broad. It is said that Horatio Nelson used to sail on the broad.
It has been recently cleaned up to remove harmful algae and those fish which eat the good algae. It was formed by digging for peat in medieval times which was used for heating. Once dug, the holes became flooded. The fens around this broad is the largest fenland expanse in the UK and contains rare vegetation. It is home to species isuch as bittern, marsh harrier, otter, fen orchid and Desmoulin's whorl snail.
