Chew Stoke Flood was a heavy rain event and severe flash flood which occurred on 10 July 1968, affecting Somerset and Southwest England in particular the Chew Valley and some areas of Bristol, notably Bedminster.

[1] The River Chew suffered a major flood in 1968 with serious damage to towns and villages along its route, including sweeping away the bridge at Pensford.

[2] On 10 July 1968, torrential rainfall, with 175 millimetres (6.9 in) falling in 18 hours on Chew Stoke, double the area's average rainfall for the whole of July,[3] led to widespread flooding in the Chew Valley, and water reached the first floor of many buildings.

[3] Fears that the Chew Valley Lake dam would be breached caused considerable anxiety.

[2][5] On the southern side of the Mendip Hills at Cheddar the flow of water swept large boulders down the gorge and damaged the cafe and entrance to Gough's Cave,[6] washing away cars.
