My posting of a few days ago (see link below) regarding the consequences of heavy rain locally was picked up by our local Champion newspaper and in turn a resident contacted me with regard for the potential of flooding in the future associated with Whinney Brook/Dovers Brook.
To explain I’ve taken a few photos of where 3 brooks/streams combine yards away from the Cheshire Lines Path/Trans Pennine Trail on the western edge of the Town:-

Footbridge across Dovers Brook where it is joined by Whinney Brook at the far corner of the Maghull High School site.
The confluence of Whinney Brook and Dovers Brook as seen from the blue bridge in the 2nd photo. Whinney Brook crosses Maghull east to west.
Another confluence just few yards further back up Dovers Brook – the stream on the left has come down from behind Fouracres.
The photos above were taken after the recent floodwaters had subsided on 29th February. There are of course other tributary streams joining Dovers Brook and eventually about two thirds of a mile north of the 1st photo Dovers Brook spills into the River Alt.

Having said that the problem, faced at times of heavy rain, is the long-standing one of the Alt being too high for Dovers Brook to empty into it, which in turn backs up Dovers Brook to flood. As I’ve said previously, there’s nothing new about this problem it’s just that we see it happening more often these days. The next photo shows what happens when things get really bad:-

The purpose of this posting has been to try to illustrate the problems on the western side of Maghull due to its low lying land and the drainage system that, other than in flood conditions, keeps in drained. The worry of the resident who contacted me most recently is that with future rainfall expected to more regular and even heavier will the Maghull area suffer bigger flooding events especially as more agricultural land is built upon (as part of Sefton Council’s Local Plan) which presently soaks up much of the rainwater.
Of course I’m no drainage engineer or climatologist but you won’t be surprised that I share such worries……..
