The River Stour at Bear Mead (made up of the five green fields on the South bank 2 miles West of Wimborne). The East neighbour is Eyemead, owned by The National Trust.
Face on Pipe Scale
River height is measured using a 4.0 metre pipe-scale. The scale gets corroded by deposits from water plants and creatures, particularly in warmer months when the river is low and stable. The corroded pipescale is replaced regularly by a newly painted pipescale. Care and the correct equipment is needed as the scale is surrounded by deep mud on the bottom. Dates when a replacement was performed are shown by a green triangle on the graphs below. The river needs to be 160 or lower. For high river states, when the wet fields prevent approach to the pipe-scale, the river height is estimated by extrapolation from the Environment Agency heights at Blandford
