This Flood Alert remains in force. Flooding is possible this afternoon and overnight into Thursday 30th December. Last night’s rain has caused river levels to rise and we expect these to remain high throughout the rest of today and into tomorrow morning. This may result in flooding to low lying land and roads close to rivers this afternoon and overnight into Thursday morning 30th December. However, flooding to properties is not currently expected. Take care near the areas of concern and monitor your local weather conditions. We are monitoring river levels and have staff in the area checking for and clearing blockages. This message will be updated on Thursday morning or earlier if the situation changes.
For some strange reason the BBC never sent us a press release beforehand, but it has recently come to our attention that the Top Gear team have been filming in Davidstow Woods and on Davidstow Airfield. The first intimation of this surreptitious activity came via Twitter:
More recently the three Top Gear presenters have been seen debating amongst other things whether a cream tea should be constructed jam first. Or not! There is of course no debate whatsoever:
To add insult to injury Paddy McGuinness then had the temerity to tweet this:
Confirmed Covid-19 cases across Cornwall have been slowly decreasing recently, but that is about to change. Here is the current national case rate graph:
Here too is some recent news from London:
Of course we don’t have many towns here in North Cornwall, but a few miles up the A39 from Davidstow the (5 days delayed) rolling weekly case rate in the Bude MSOA has just crept above 800 again:

After a break in reporting over the Christmas holiday the UK Government is issuing Covid-19 data again. There has been a big jump in UK wide cases today, no doubt partly due to some catching up after Xmas:
Today’s strong onshore winds mean that flood warnings are still in place for this evening’s high tide. Meanwhile winter has officially arrived. There have been several showers of hail here in Davidstow this morning. Here’s one of the heavy showers on the radar rainfall (and hail!) map:
The Magic Seaweed surf forecast for today promised the arrival of a new long period swell:
Plan A for today involved getting in the water and out back before said swell arrived.
When that failed to materialise plan B involved heading for spot M with video recorder and tripod in rucsack.
When that failed to materialise plan C involved heading for high tide Crackington Haven. When that did materialise here are the sights that met our sore eyes:
We also recorded some moving pictures, including sound effects:
Finally, for the moment at least, the almost imperceptible damage to my left arm after the almost undetectable injection of what ultimately turned out to be a dose of the Moderna mRNA Covid-19 vaccine for my booster jab:
The facts are that we have a combined sewer system in this country, meaning rainwater and sewage both flow into it. This means that heavy rain and storms can lead to additional pressure on the system that needs to be released”. lt is not a coincidence that discharges happen most often during or after a storm. lf this pressure is not discharged the wastewater – including sewage – will back up into the streets and into people’s homes. This is not hyperbolic; it is a fact. The age of this Victorian sewerage system means that the complete elimination of storm overflows would be extremely challenging. Unfortunately, they have always been a part of our wastewater infrastructure and until now little action has been taken by any government or party.
One of the recent amendments in the Lords would have required work to be done to eliminate sewage discharges, and I was one of several hundred MPs who opposed it. Initial estimates of the work necessary to achieve this are in the region of £150 billion and upwards. To put that in perspective, this is more than the entire budget of the NHS. These costs would inevitably be passed onto taxpayers or water bill payers. No sensible legislator could have backed this. I am of the view that the water companies should foot the bill for improvements over time and not the taxpayer, so these improvements must be manageable.
That rather begs the question about where we would be now if the necessary improvements had been started a decade or two ago? And indeed what the actual cost would be in today’s day and age!

This tweet from Professor Dieter Helm seems apposite at this juncture?

After almost continuous heavy rain, hopefully the end is in sight for the current series of pollution incidents on the beaches of North Cornwall. Several beaches are not being monitored at this time of year, but currently Widemouth Bay and Trevone are the only ones still marked in red on the Surfers Against Sewage water quality map:
Hopefully those two will get the all clear tomorrow

In answer to my question above about “the actual cost of the necessary improvements to the UK’s ageing sewage infrastructure”, the Government has just announced:
An independent research project that considers options, costs and benefits for reducing storm sewage discharges in England.
Reducing sewage discharges from storm overflows is an important priority to protect the environment.
This research, the first assessment of its kind, was commissioned by the Storm Overflows Taskforce – made up of Defra, the Environment Agency, Ofwat, CCW, Blueprint for Water and Water UK – and funded by Water UK.
The independent research, carried out by Stantec, presents a detailed overview of potential approaches that will act as an important evidence base for government action.
The Storm Overflows Taskforce will now consider the report and its recommendations to:
support the development of the best mix of policy solutions
inform the government plan on storm overflows to be published in September 2022.
The report itself evaluates the costs and benefits of a range of scenarios. The methodology used is summarised like this:
The policies tested consider the universal implementation of permits to control storm overflow spill frequency to an average of either 40, 20, 10, 5 or 0 (zero) times per year (named F40, F20, F10, F5 and F0, respectively).
Three scenarios are also considered, describing the engineering approach used to deliver policies. The first relies on a conventional approach to capture spills from storm overflows using network storage (W) which is sized sufficiently to capture spills and allow for these to slowly return to the sewer network for treatment.
The other two augment the conventional approach with partly or wholly nature-based technologies (retrofitted SuDS) at two levels: 10 percent of impermeable area controlled (S10) and 50 percent of impermeable area controlled (S50). In this context, controlled means that these flows do not enter the combined sewer system. The SuDS solutions are implemented in addition to sewer network storage; therefore creating mixed grey-green solutions. The S10 level of SuDS is at a modest level across the catchment, whilst the S50 level is at a high level. Controlling runoff from 50% of impermeable area (S50) is broadly equivalent to preventing all highway runoff entering combined sewers in a fully combined catchment.
The costs of the various approaches are summarised in the following infographic:
There seem to be a wide range of available options that cost considerably less than £150 billion, and that’s before accounting for the associated benefits.
Schools have gone back and the clocks change in a couple of weeks, but Covid-19 is still with us. In actual fact it’s on the increase again. Both nationally:
and here in the Camelford MSOA, where we now find ourselves in the top DHSC category with a case rate of 889.8 per 100,000 people per week:
Just down the A39 “Atlantic Highway” in Wadebridge the rate is now over 1,000.
Further west the top spot goes to Camborne West, with a case rate of 946.4:
As you can see from the maps there are several other area across Cornwall in the 800+ category, whilst across Cornwall as a whole the average case rate is 539.5, an increase of 15.6% compared to a week ago:

Further to the BBC report in the comments below, the The Royal Cornwall Hospitals Trust is “tweeting” much the same story:
They are also providing their current Covid-19 statistics:
A big swell was forecast to arrive on the coast of North Cornwall last weekend:
Discretion is the better part of valour, especially at our advanced age. Hence we merely admired it from afar on Friday evening:
The waves were significantly smaller on Saturday, so the Davidstow.info editor-in-chief and artist-in-residence packed our gear into Lisa, our Nissan Leaf electric vehicle, and headed for Widemouth Bay:
We even managed to record some moving pictures of the scene at the seaside, as did Dave at Watergate Bay!
P.S. We also managed to record some video footage whilst immersed in the Atlantic Ocean. In episode one your intrepid editor inadvertently found himself in the midst of a sizeable closeout, and managed to breathe in some seawater of hopefully unadulterated quality:
