River Ant  The River Ant is a tributary river of the River Bure in the county of Norfolk, England. It is long (of which 8.75 miles are now navigable), and has an overall drop of 27 metres from source to mouth. It is said that the Ant was formerly known as the River Smale and that this is the origin of the name of the village of Smallburgh. The river's source is just east of the village of Antingham in North Norfolk at Antingham Ponds. Just below the pools the river's route has been used as a canal in the past, starting at what was Antingham bone mill. An Act of Parliament established the North Walsham & Dilham Canal in 1812, as a wide gauge canal able to take a Norfolk wherry. It was built at a cost of £30,000 and opened on 25 July 1826, making the river navigable as far as Dilham, where the river widens and deepens. It carried manure, offal, flour, coal, and farm produce. In 1885, the canal was sold for £600, but the canal company's solicitor disappeared with the money. The flood of 1912 washed away several staithes. The wherry "Ella" made the final trading journey on the canal from Bacton staithe in 1934. The canal was never nationalised and still belongs to the North Walsham Canal Company. The river, now in its canal form, curves around the north east of the town of North Walsham passing Bacton Wood Mill. Below Bacton Mill the canal reaches a lock at Ebridge mill. The lock is in poor condition but it is hoped that this section of canal will one day be restored and made navigable again. Further on at Briggate Bridge there is another mill and another disused lock. The Ant Broads & Marshes NNR is a national nature reserve. At Honing Bridge the course enters The Broads, administered by The Broads Authority. Here the canal cuts through a marshy wooded area called Dilham Broad and again curves north east around the village of Dilham, passing under Tonnage Bridge. Below Tonnage Bridge are the last limits of the Navigation through Broad Fen before reverting to the river. Just before Wayford Bridge, a branch of the canal called Tyler’s Cut runs off to the west. This branch links the villages of Dilham and Smallburgh to the river and the rest of the broads although it is at the moment only navigable by very small boats.
