We had a 100mm from Friday morning to 6 Saturday night!!Here have measured 200 mm including the 20mm yesterday in period 23 September to November 3rd. And in those 40 days only had 9 days without some rain falling. Those 40 days coinciding with the exact period for sowing autumn cereals. Local long term annual average rainfall is 580mm. So a third of the annual average rainfall in 40 days bang when want to sow winter wheat and barley.
While some river drainage maintenance possibly due any amount of dredging would not have prevented soil saturation on clay soils with the exceptional amounts and periodicity of rainfall in South Lincolnshire in the past 40 days.
