Project summary

Edit project overview to modify the project summary.


The Environment Agency's Fisheries & Biodiversity and Operation team along with Milton Keynes Park's Trust repaired a section of eroded bank on the Great Ouse at Stony Stratford.
We used soft engineering in the form of willow bundle revetments to reinforce and protect a section of bank that had become eroded as a result of livestock poaching and flow pressures from Stony Sluice.
