Chalfont St Peter: Vic Wotton Bridge

Image: © Nigel Cox Taken: 25 Apr 2010

This footbridge over the River Misbourne is dedicated to the memory of Vic Wotton (1916-2000), a vice-president of the Chiltern Society, who campaigned from the 1970s for the restoration of the River Misbourne from the low flow conditions from which it had suffered in the 20th century. The Misbourne is a classic chalk stream rising in the Chilterns and even without any human activity would be prone to drying up occasionally as ground water levels dropped and rose with rainfall amounts. The problems initially arose when a mill leat upstream was allowed to deteriorate in the 19th century once the mill was converted to steam power, causing a loss of river water through the leat banks. Then, with the growth of the population of places such as Chalfont St Peter in the 20th century and consequent greater demands for water, abstraction from the ground aquifers was made with a series of boreholes, thus generally reducing the groundwater level. Finally a sewage treatment works was built, but the unreliability of the water supply meant that there was an inadequate supply of it to dilute the treated sewage and the works was closed. Large holding tanks were then built to contain the sewage until it could be transported for treatment elsewhere. Eventually this operation was by-passed and the tanks demolished. In so doing it would appear that further damage to the river banks occurred and there was a further loss of water through them. For a comprehensive history of the situation and for the remedial plans please see the Chiltern Society's pamphlet here http://www.chilternsociety.org.uk/dloads/SavingTheMisbourneProposal.pdf I am pleased to say that on the day the photograph was taken the River Misbourne was flowing with just the right amount of flow that Vic Wotton would have envisaged.
