River Blackwater

Flood Alert

Water levels in the River Blackwater are high and rising. Last night (Saturday 14/12/2019), 15mm of rain fell in under 2 hours at Romsey. Whilst only a modest total amount of rain, it follows a prolonged wet period (over 170% of the long term average rainfall between September and mid December). Consequently river levels are rising again. By 07:30 this morning (15/12/2019), water levels will be high around the Mill building at Wellow. Some minor ponding of water will also affect low lying land from Landford to Wade Bridge. For the next 5 days showers are forecast. This additional rainfall will keep the river above the seasonal high level, so please ensure that any pumps used to protect property from flooding are operating. We’ll ensure the River Blackwater is free of blockages. This Flood Alert will be updated by 11:00 on Monday 16th December 2019.

This information last updated 7:16am, Sunday 15th December.
