Increasing life chances – addendum

Simon Hirst – River Esk Project Officer

A redundant weir on the River Dove at Low Mill in Farndale has recently been removed by the Estate in partnership with the National Park Authority, the Environment Agency, Natural England, and the East Yorkshire Rivers Trust. The weir was in a poor state of repair, and erosion was occurring around the side of the structure. Its removal will allow natural river processes like the movement of river substrates to occur , and also allow migratory fish to move up and down the river to spawn.

The River Dove is a tributary of the Yorkshire Derwent. Part of the River Derwent catchment is designated as a Special Area of Conservation for a very rare fish species called the River Lamprey. These fish would also spawn (lay their eggs) in the upper catchment (in areas like the River Dove), but they cannot access these sections of river due to a large number of barriers, such as weirs, in the catchment. Removing these barriers will also allow other species such as Atlantic salmon to access these important spawning areas too.
