Flooding – Getting More Information
- Who should be doing what for you and the wider community
- Where to get the best weather information
- Where to check the water levels in the River Hart
Who (should) do what
This is a House of Commons Briefing Note on sewer flooding which is relevant to our local situation.
Hart have their own emergency planning pages,with a wide range of useful information and contacts.
The following sources of weather information are well regarded:-
- The MetOffice provides one of the best forecasts (make sure you set it to the most local weather station – usually “Odiham”)
- Accuweather has a real-time radar (include the past 30 minutes so you can gauge how fast rain is approaching), it works just like a Google Map
- Crondall Weather (run by our own Neil Docker) provides a “nowcast” and historic data . Neil’s system is so good it provides data to the MetOffice as part of their small observations scheme and he includes a whole host of additional and fascinating information!
Water Levels in the Hart
The water levels in the river Hart are monitored by the Environment Agency at 2 locations:-
- Well Road Pond, this is 84m AoD (Above Ordnance Datum)
- Redlands Lane Bridge, this shows the river height with a base line that is claimed to be: 81m AoD, but comparison with the physical depth marker suggests the baseline (ie. height = zero) is more like 80.97m – it may be important as every centimetre counts!
The data from these 2 sensors is normally collected every day (by remote access), but at times of high risk it’s collected more often. It seems their solar-cell/battery based power systems limit such collections!
If you know of more useful sources of information that you’d like us to add, please let us know.
