This Thames flood alert is going to get worse for Hertford.
If the Thames breaches (which it has) it will only go one way - The Lea.
I am not talking about the most amount of water we have seen in 300 years, dredging rivers etc; Mummy Nature will flow up to the Lea Navigation very quickly, possibly within 2 weeks.
Excessive water and sewer drainage impact from The Thames into the finest of rivers = major problems if the Lea may burst in the near future.
Several examples are being seen today of Mother Nature on TV which we cannot control, yet take responsible action.http://www.thameswater.co.uk/about-us/10092.htm
