 In common with most of the rivers of Suffolk and Norfolk, the Waveney is relatively flat, falling around on the section between Hoxne Mill, near to its junction with the River Dove, and Beccles Bridge, where the river is tidal.These points are apart, giving an average fall of 1 in 1,970.Despite these factors, the river has powered at least 15 mills, evidence for some of which indicates that the river has been used for this purpose for over 900 years.
